Soundcore Sleep A30 by Anker Sleep Earbuds, Smart Active Noise Cancelling Sleep Headphones, Adaptive Snore-Masking System, Ultra-Comfort for Side Sleepers, 45H Playtime

Good product. I had my doubts but Soundcore A30's are very nice. Setup was fairly easy, Soundcore connected to my iPhone bluetooth settings. I watched some Youtube videos as a precaution to get more information. All I can say is buy these Sleep Earbuds...I really like them. Now some folks might want to try various sleep inducing effects the Soundcore offers, like sounds of rain, waterfalls, soft music, violins playing low and sweet etc..go for it. Experiment with all the added features have fun. I got noisy 2nd floor person pounding on floor acting silly all night..but the Soundcore have allowed me to get decent night's sleep NOW. Very happy. People in apartments can piss you off with unruly juvenile behavior!! These Soundcore Earbuds saved the day. I usually charge earbuds in case 1x a day, ( charge can last all night ). The case can be recharged every 2-3 days. Never had to worry about reconnection or hurting in ear. I leave them in ears for 5 hours sometimes, or longer. You can delay some setup details till later, I took mine out the box..charged them, connected them to wifi and bluetooth--also you have many additional parts for tips for ears..no worry there!! Check your phone for Noise Cancellation, very easy, my buds stay charged at 100% and Noise Cancellation works great. I snore, I am sound sleeper, and the SoundCores keep me comfortable and finally I am getting good sleep.

I did not like these at first. I knew would take time to get the right fit, but had quite a few nights waking from ear pain. That was with the silicone buds, the memory foam that they list as "not as comfortable" is far more comfortable for me. Once I got the fit right, these have been life changing. And I do mean that, and will explain - I work on a ship, which is running 24/7, and full of inconsiderate @sssholes. Working night shift and sleeping during the day? People will slam door, yell in hallways, etc. Add in loud PA announcements on top of that. According to my Oura ring, I was getting woken an average of 10 times a night/day. 5.5-6 hours broken sleep a night. I was miserable, always tired, in a job where being tired and unaware is horribly dangerous. Try as I might, the inconsideration of others never got better. For awhile I managed with silicon earplugs and a manta sound mask, along with white noise. Still would get woken up. Brought these A30s out, figuring even some ear pain was worth it. After a few nights I got the fit right and getting 8 hours sleep a night. I don't wake with ear pain, sometimes a tiny bit of soreness. The battery life is good enough, be nice to be better. I find that once I get to my room I want to put these on, as I am then in my own world, with calming rain sounds. If I get 8 hours sleep, these have 10% battery left when I wake up. Id prefer longer so I could have a chill, quiet morning before the sounds of chaos wreck my mood. The ANC is actually really good. Those that complain did not give it time. Obviously if you do not have a good fit, you wont get as much noise cancelation, but the ANC starts minimal and increases over next few minutes. I think its learning the noises and slowly adjusting. I keep a fan running at night, and when I just put the buds in I can hear it, but after a few minutes, its cancelled out. Sound quality? I don't have the sound very high but sounds good to me. Very clear. These are meant for sleeping, not raging out to some metal while lifting weights. These do track your sleep, I don't know how accurately it does thought. I would compare with Oura Ring, but my sleep was so bad I got rid of my ring cause I only saw disappointment. The issue with the sleep tracking is you need to connect to the earbuds to open that part of the app. App isn't all that great in my opinion. I have not tried any of the sounds in the app, it uses Calm though. I can't speak for how it gets rid of snoring, or much of the options. There is an option to have the music turn off once you fall asleep, that one irritated me, as it got turned on somehow and I woke up 30 minutes after falling asleep and couldnt get music playing through the earbuds. Played out phone speakers instead. Trying to sort that out while half asleep not so fun. I learned to check the settings before sleep. I just use it to play continuously, then put on a 2 hour playlist of sleep sounds, and it keeps the ANC going after music stops. One other minor complaint is the foam buds they say are consumable, yet they only sell full set. Would be nice to sell a set of one size so you dont have to buy a set of all sizes just to get the size you want. Also, not sure how long the foam will last but been a month and still look new. I am a side sleeper, which probably helps some of you out. If you arent a side sleeper, these would be insanely comfortable. As a side sleeper expect to play around with sizes, and know that what seems comfortable testing may not be comfortable sleeping. Im stubborn and know I have big ear holes, but shockingly after plenty of sizing I found smaller ones worked better. I would give 4 stars, due to the app and some small annoyances, but these have been so life altering, I cannot give less than 5 stars. These have helped me so much, I'm tempted to get a second pair as a backup as I couldn't go a night onboard without these now.

These are non-functional for their intended purpose unless you require very little sleep. First, the volume level of these speakers seems very low by default. Compared to my other earbuds (an older set of Space A40s and a set of Bose QuietComfort 2024 earbuds that I tried), these required a much higher volume level across all types of listening scenarios. The volume issue is relevant because it affects the earbuds' noise masking/cancelling capabilities as well as how much battery life you can expect from one full charge. I wanted earbuds that I could use with ANC on for at least 6+ hours to block my partner's snoring. I also wanted to be able to stream ambient sounds/music/white noise over bluetooth the whole night as a sleep aid. (I tried the built-in noise masking options, including the option to customize your masking sound, and disliked how low-quality and harsh they all sounded.) These earbuds only last 6.5 hours max when brand new in my preferred mode of use. I need more sleep than 6.5 hours most nights, and because lithium ion batteries degrade, these buds would only be even partially functional as a sleep aid for me for a few months, if that. These buds thus seem like a poor value for the money for how I want to use them. The A30s also seem overpriced, even by Anker's standards, because they just announced an upgraded version of these buds (advertised to have a longer battery life than these regular A30s) that will be sold for $20 less than the launch price and advertised MSRP of the original A30s. I also strongly dislike the shoehorning of AI bloat in the updated soundcore app. The "brainwave audio" tracks are all quite annoying/distracting, imo, and it looks like Anker generated a bunch of non-cohesive AI slop images to accompany the sleep tips portion of the app. Sucks that Anker would rather generate cheap visual soup than hire designers or artists who could create cohesive and relevant art. The transition from bluetooth audio to the noise masking sound in local audio mode, which can be triggered when sleep is detected to preserve battery life, was abrupt enough (due to how much louder the the noise-masking sound with no ANC seemed compared to the volume of bluetooth audio + ANC) that it woke me from sleep several times, which was also pretty annoying. I don't care about or even really trust the accuracy of the sleep tracking features in the soundcore app/these earbuds, so I didn't test or even set up that part of the app. As far as positives go, the buds really are small and lightweight. I struggled to find a good combination of ear tips and wings that would lead to a secure, noise-blocking fit in each ear, but that's not unusual for me. The silicone material seemed nice enough, and I liked the sliding case lid. Overall, I cannot recommend the Sleep A30s as a sleep aid. The set I tried is being returned due to the short battery life when brand new and the lack of good app features or built-in noise masking sounds.

After three shipping attempts (these appear to be a high-theft item in transit), I got these (A30 "Special") and have been using them for a while. # Fit and Comfort These are comfortable, for the most part. There are a number of sizes for both the in-ear part (in plastic and in foam) and the outer-ear part (the part that presses against your ear folds to keep these in place). Honestly I couldn't see much of a difference in how the outer-ear part fit, but a bit of experimentation was able to get a good fit on the critical in-ear piece. I don't generally have any trouble keeping these in all night long. To insert these, you push the in-ear part in with the outer-ear part pointing "up", then rotate the top towards the back of your head so those outer-ear parts push against the ear folds. I did find if I "over-twist" then I wake up in the middle of the night with sore ear canals, because doing so causes the inner ear part to push against the side of the ear canal, and more of a twist isn't necessary to keep these in all night in the first place. # Noise Suppression and Cancellation Putting these in (I use the foam inner ear pieces, which it says offer better passive noise reduction) the noise suppression is noticeable and significant. I can't hold a conversation with them in, although I definitely can tell if the other person is sleeping. So noise suppression is strong, across the spectrum. Noise *cancellation*, however, is a different beast entirely. I have a hard time even seeing the difference between noise cancellation on and off. It just doesn't seem useful, especially coming from using my AirPods Pro during the daytime. Really makes me wish Apple made a version of AirPods for sleeping in. Being able to switch between "transparency" mode and a better-working "noise cancellation" mode would be very welcome here! # Battery life I find that if I run these on bluetooth all night long, they *might* make it through the night. If I have it switch to "local audio" (up to three "soundscape elements" like rain falling, thunder, waves lapping on a shore, etc) when it detects I am sleeping, they easily last through the night. I haven't had any issues with the switch to local mode; it has always accurately determined when I am asleep to make the change, so I fall asleep with a "brain wave" soundscape, and wake up with my chosen local audio running. # The App The SoundCore app is IMHO a bit of a mess. I went looking at a couple of well-reviewed alternatives (Calm and Better Sleep) and found that those apps are even *more* of a mess, and relatively expensive ($70-80/year after a 1 week free trial) to boot. Also, those other apps only work in "bluetooth" mode, so the ear buds would be prone to dying before the morning. So, I went back to using the SoundCore app. Unlike the expensive apps, you are very limited in how you construct soundscapes, only able to choose *three* components. And these soundscapes can get repetitive because of that. Another note on the app: you can't do anything in the app without the earbuds connected, and they will only connect when out of the case or in the case with the lid open. Many times it is very slow to register that the earbuds are connected (that is, I have the earbuds connected to my phone over bluetooth, even playing music on them, but the app says I need to connect them). Eventually, tapping on the "connect" button will pop up a warning saying that continuing will disconnect the current earbuds, and if you continue or cancel at that point it "sees" the earbuds. # Controls These operate on a "multi-tap" control scheme. I find this to be rather uncomfortable because each tap pushes in on my ear drum with pressure, and have also had it inadvertently register taps when I'm just adjusting in bed. You have double-tap and triple-tap settings, so between the two earbuds you can control four things. By default those are "bluetooth <-> local audio", "noise cancellation", "volume up", and "volume down". No play/pause. No next/previous track (which makes less sense in a sleep earbud anyway). I really miss the better-thought-out control schemes of Apple headphones here. # Technical Glitches While the earbuds snap confidently into place (magnets, how do they work?) in the holder, annoyingly often they either don't make good enough contact or just don't detect that they are in the holder. I have found that in the morning I need to put the buds in place then wait a few seconds to verify the light "slow pulse" on *both* earbuds. I didn't do this once, and when I went to use them the next night one of the earbuds' battery was dead so I needed to re-seat it and wait before putting them back in.

Full disclosure - I have smaller ears and canals, and I am a side sleeper and I have been using these for the last 7 days. I am moving to a new town and decided to rent an apartment for a year to help me decide where to buy a house. Well, the apartment walls and floors are not well insulated. I hear footsteps, creaking floors, snoring through the wall, and sometimes can hear the tv shows they watch. Needless to say, I was having serious trouble sleeping. I could fall asleep pretty well (go to bed early), but I would be awakened at some point, or several points, in the night by all these noises, banging, walking, creaking, and snoring and was not able to get back to sleep. I needed something to help. I tried Mack's foam ear plugs. They work pretty good for noise reduction, but my ears would hurt and throb making my sleep difficult in that way. I even had the small ears size. They were comfortable to side sleep with. I bought some fake Loop alternatives as just ear plugs. They were comfortable, did not throb like the Mack's in my ears, but did not block out enough sound. When I tried a bigger ear plug piece, I found the throbbing ear syndrome again. These were comfortable to side sleep with though. I then bought a cheap knock off brand of "sleep buds". They were the most comfortable thus far. They would bluetooth to my phone so I could play either music or some white noise from my phone. They claimed to have ANC. They were helpful to block out some sound because of the ear fit, and because they could bluetooth to my phone for music or white noise. However, with the ANC on or off, I did not detect any difference in sound reduction. These were kidney bean shaped sleep buds and did not stick out much from my ear. The ear plug piece was comfortable, but the harder plastic part would start to be annoying after a few hours when on my side. They were ok. Sound quality was decent. Maybe a C+ for an overall grade for these. However, they didn't stop all the sounds and I still woke up occasionally. I hesitantly tried the A30's. This is no small investment! With the rubbery ear plug piece and ear fin, these buds were comfortable. While on my side, they have been the most comfortable thus far. I can sleep well with them in actually. I still have a little bit of pressure while on my side, but some nifty pillow management helped relieve the pressure. I am using the attachments they came with out of the box. I really like the white noise sounds. I have Still Lake as my favorite. It is a sutble sound that helps my brain drift off. With the fit of the A30 alone, I can block out most of the noise for the night with these standard size pieces without using ANC. Last night, I had both my wife snoring and banging on the ceiling above. (To be honest, my wife's snoring is not super loud but enough to wake me up). Then I realized I didn't have the ANC on. Well, i turned the ANC on and WOW what a difference. It was almost like I had over the ear headphones with ANC on. All that noise disappeared. I was very impressed, at least I recall being impressed. I was asleep!! The sound quality is perfect for night time sleeping. In reading other reviews, I agree that these are not your everyday all day ear buds, they are really designed for sleeping only. The ANC works really well and I noted quite a difference between on and off. Last night I set them to use ANC until I was alseep and then go to local mode. After 8 hours, I still had 30% of the battery left in each ear bud. So far, the battery life has been great. I have yet to spend a whole night with bluetooth and ANC on, however. I haven't needed to. I know at $200 it seems like a lot to spend for ear buds that you only use for sleep and that aren't designed for super high quality audio sounds. However, this week has been the best sleep week I've had in two months since those neighbors upstairs moved in. You do need several nights to get used to the fit and feel. Not because they are uncomfortable, but because when something new is in your ear and you aren't used to it, it can feel funny and weird which may keep you awake instead of helping you sleep. But, give it a few nights, and if you are like me, they get more comfortable the more you wear them. I can sleep on my side with these but I need a soft pillow. A really firm pillow would hurt my ears after a few hours, as it would everyone else with anything in their ear. Everyone is a different size and shape, but I have found these A30's to be comfortable, and of high quality. The app is full of options to help customize the experience, and they do what they claim they will do. After this week, my wife (who is very thrifty) is asking if she can try these out and maybe get a pair because she notices such a difference in my morning wakefulness. Hope this helps those of you out there like me needed something to help get your sleep back. I would definitely buy again and am grateful for this product.

I've had these sleep earbuds for about 4 months, and originally bought them for the ANC and snore masking. They're a decent pair of earbuds that do a good enough job blocking out most noises comfortably. However there are some things that you should know before considering buying. The ANC function works as intended but consumes the battery life to the point of it dying in the middle of the night. The app even acknowledges this and recommends that you only keep the ANC function on until you've fallen asleep. Sometimes the earbuds don't connect to the charging case and won't charge even when it seems like they will. There has been quite a few times when I open the case at bedtime, and one earbud is 10% charged as to the other one which is fully charged. This has led me to staying up later and waiting for the earbud to charge enough to use. The charging case itself charges fairly quickly, and will be at full charge usually within a few hours. The feel of the earbud itself is very comfortable. It may take some getting used to for a week or two, but by then every time I wore these earbuds it barely felt like anything was there even when I slept on my side. The Soundcore app offered a decent variety of white noise, meditation music, and even some guided meditation tracks that you can download and load on Local mode, or the mode that isn't connected through Bluetooth. You can have up to three individual tracks playing at once and can edit the volume in which they are played at. Overall, these sleep earbuds are decent. When it comes to the ANC and snore-masking claims, it's very flawed, and I would not recommend getting these earbuds if you're looking for active noise cancellation that lasts the entire night. However, as someone who is a light sleeper, these earbuds did help block out a majority of noises that would otherwise wake me from my sleep when they worked as intended.

TLDR: Made my sleep worse because: Bluetooth disconnects easily and I'd have to mess with phone. Brainwave audio has pinging sounds that startled me repeatedly when almost asleep. Ear pain when side sleeping. I got far worse sleep using these than I did with my Loop ear plugs. I was using the Brainwave Audio over bluetooth to fall asleep and had the ear buds switch to local after I was asleep and auto switch to bluetooth when I would wake up. (I sometimes wake up in the middle of the night and have difficulties falling back to sleep.) This feature worked correctly maybe twice tops. One of the big problems is the bluetooth disconnects easily. You have to have your phone very close and at an optimal angle, or the Soundcore app will disconnect and then you have to open the app, connect, and hit play. I kept losing connection with my phone on low nightstand at a hotel, and at home I would lose connection if I used the bathroom a few yards away (I have wood walls with no insulation). I set one ear bud tap control to play bluetooth. It connected to the Soundcore app and played the Brainwave audio first time I tested it. After that, it would connect to and play my closed radio app instead of the audio from open SoundCore app. The Brainwave audio kept waking me up. At first, I really enjoyed the brainwave audio sounds. I liked how it went from ear to ear and helped me turn my brain off, and it worked well if I was super sleepy and drifted off quickly. BUT every single one of them have an alarm-type pinging type sound that eventually shows up and gets loud and repetitive at points - longer the audio was played, the worse it got. So those nights I was having a hard time going back to sleep at 3am, the brainwaves audio kept startling me awake with "PING, ping, PING, ping" just as I was drifting off to sleep. I'm a sometimes side sleeper with tiny ear canals. The earbuds were ok when I was on my back, but they dug into my ears when on my side. The rubber parts were fine - it's the hard body of the earbuds that was digging into me. The earbuds made me hard for me to get comfortable on my side and be able to fall asleep, and I woke up more than once with my ears tender to the touch where the earbuds dug into my ears. (I HAVE to sleep on my side sometimes due to leg twitches, so it's not just a simple "well don't sleep on your side.") My Loop earplugs don't cause this problem for me, and I rarely notice them when I'm on my side. These would work if you don't get out of bed, don't get startled easily (or don't use their brainwaves), and have different ear anatomy they I do.

I typically do not leave product reviews but I am compelled to do so as these headphones changed my life. I am a very light sleeper and my partner is a very heavy and aggressive snorer. So much so if I change rooms I still need to wear headphones to block out the snoring. I also have very tiny ear canals and am a side sleeper. All things considered, I have tried just about every headphone, earbud, headband you can think of. I came across a recommendation for these and was skeptical based on the reviews. But I was desperate and decided to try them out. I have waited a few weeks to review so I didn’t jump to any conclusions, but for two weeks straight I have not heard a second of snoring. I genuinely didn’t get any sleep the first night I wore them because I kept thinking something was wrong because I DIDN’T hear anything. They are also extremely comfortable, as much as they can be with sitting in your ear all night. A few things I will note. The app is terrible. The functionality is clunky, you can’t connect without having the earbuds activated, and really it doesn’t do much in terms of what a sleep app could. That being said, the noise canceling soundscapes work really well for my sleep style so that’s great for me. I run them on “local mode” and not thru my Bluetooth and I also run them continuously thru the night for about 7 hours and have yet to lose a charge. There is also a stark difference between regular mode and noise canceling mode. I’ve accidentally turned off the noise canceling mid-sleep and it honestly does less than those over the ear headbands. So keeping that on is important. I also appreciate the way that the noise canceling sound works so I don’t need to have the volume turned on high to mask the sound. I’ve always worried about in-in white noise and hearing loss but these I’m about to keep reasonable and still get the desired effect. I also wish they would come with XS memory foam ear tips. The small is too big with the firmness but the silicone ones are fine. But there are 4 sizes of silicone and 3 of memory foam to choose from so they are very adjustable. In terms of the value - my sleep is priceless. Yes these are expensive but for me, they were worth every penny. If it’s between getting mediocre sleep with cheaper headphones or getting uninterrupted sleep with expensive ones, I’ll spend the money any time. I think the one thing I wish would be better, especially for the name brand and price, is that app. It leaves much to be desired. Then again, I guess they put all their energy into the earbud itself so I can’t get that too bent out of shape. As far as I’m concerned these are the best sleeping earbuds on the market to cancel out snoring without damaging my hearing in the process.

I’ve been using it for a month now, and it’s the best purchase I’ve ever made! I’ve been sleeping so much better, the noise cancellation is absolutely amazing, it’s comfortable to sleep with, the app is super easy and super cool. I also use as normal earbuds to listen to music and specially for audiobooks, when I don’t want to be distracted by the outside noise. Absolutely amazing product!

The active noise cancelling is amazing

Tolle Kopfhörer für seitenschläfer! Ich bin begeistert. Sie passen sehr gut. Da ich kleine Ohren habe passen mir viele Kopfhörer nicht. Die Sleep A30 sind aber perfekt. Mit den vielen extra Aufsätzen kann man sie passgenau an die eigenen Ohren personalisieren. An muss darauf achten dass die gut abdichten und ich habe sie bisher noch nicht einmal verloren beim Schlafen. Sie halten wirklich gut. Außerdem sind sie auch beim seitlichen schlafen auf einem relativ "harten" Nackenkissen kaum zu spüren. Nach 2-3 Nächten hatte ich mich dran gewöhnt und sie stören überhaupt nicht. Zur Funktion: Man kann die Kopfhörer im Bluetooth Modus betreiben und dabei eigene Musik z.b. über Amazon music abspielen oder aber auch Schlafgeschichten über die soundcore App, sowie auch Gehirnwellen Audios oder Meditation. Alle diese Audios können mit ANC gespielt werden, das ANC der sleep A30 unterdrückt dabei tiefe Geräusche wie Schnarchen. Ein Fernseher mit höheren Geräuschen wird dabei aber noch gedämpft durchgelassen. Das ANC der Sleep A30 ist speziell auf das Schnarchen abgestimmt. Da funktioniert es wirklich total gut! Ich bin begeistert. Weiter kann man bei den Kopfhörern ein lokales Audio auf die Buds runter laden. Dieses Audio kann ein Weißes rauschen sein (welches man auch selbst konfigurieren kann) oder aber auch ein "schnarchmaskierendes" audio. Dieses maskierende audio kann in Verbindung mit der "dynamischen schnarchmaskierung" verwendet werden. Soll heißen: die Kopfhörer können das Schnarchen mit dem audio so übertönen dass das Schnarchen nicht mehr wahrgenommen wird. Und es funktioniert wirklich! Ich bin begeistert! Wichtig ist: bei der Schnarchmaskierung müssen die Kopfhörer im lokalen Modus sein und das ANC muss ausgestellt sein. Dann säuselt das Lokale Audio vor sich hin und wieder lauter und leiser sobald das Case der Kopfhörer ein Schnarchen wahrnimmt. Mich hat anfangs das einstellen dieser Funktionen etwas überfordert. Nach Recherche im Internet und Kontakt Aufnahme zum Support von Soundcore kann ich folgende Tipps abgeben: Wenn man die Kopfhörer im Bluetooth Modus mit einer Schlafgeschichte zum einschlafen betreibt, sollte man die Einstellungen " automatisch wechseln nach dem Einschlafen - lokalen Modus an, ANC aus" wählen, dann ist die schnarchmaskierung aktiv beim Schlafen. Die Kopfhörer erkennen das Einschlafen sehr genau. Man kann ebenfalls einen Wecker stellen der zuverlässig weckt. Bin begeistert. Der schlafbericht wird ebenfalls erstellt, egal ab man die Funktion "Schlaf beginnen" nützt oder nicht. Die Kopfhörer machen vieles automatisch. Was bei mir nun leider nicht so gut funktioniert hat, war der Wechsel in den lokalen Modus ohne ANC über die "Schlaf beginnen" Funktion. Da habe ich es leider beobachtet, dass ich das ANC selbst ausschalten musste und der lokale Modus war zwar laut App aktiv aber es spielete kein audio. Der Support konnte mir dabei nicht wirklich helfen. Ebenfalls hat der schlafbericht (ob über "Schlaf beginnen " oder automatisch) keine Daten zum schnarchen aufgezeichnet. Die schnarchmaskierung hat funktioniert aber es wurde nicht getrackt . Der Support meinte dazu dass die Kopfhörer einen defekt hätten und haben sie ausgetauscht, jedoch haben die Ersatz Kopfhörer ebenfalls keine Schnarchdaten erfasst. Ich denke dass da ein Problemchen mit der App oder der Firmware besteht, welches hoffentlich behoben werden kann. Na ja Da ich die Kopfhörer noch nicht all zu lange habe bin ich immer noch am ausprobieren. Übrigens, zum Akku Verbrauch: ich kann die Kopfhörer 3 Nächte ohne Probleme nutzen. Am Abend mit 100% ins Ohr, am Morgen haben sie noch zwischen 40% und 10%. Das Case ladet die Bus dann wieder auf 100%. Das Case hält bei mir bis zu 3 Tage bevor ich auch dieses dann laden muss. Somit also bei mir kein Akku Problem. Aber ein positives erster Fazit zeigt sich schon jetzt: ich kann neben einem lauten Schnarcher jetzt deutlich besser schlafen. Der Kauf hat sich also schon jetzt total gelohnt!

Bra ljud och ANC. Bekväma att använda. Bra programvara med rikligt med alternativ att välja på. Toppenprodukt helt enkelts.

Only had these for three days, but sofar my sleep quality has improved. Great if sleep next to a snorer
