Best earbuds ever.
Super comfortable, I forget I have them in sometimes. Really easy to click off annd talk to my coworkers without having to take them out. After over a year they will still play for 9 hours straight without a charge, they sound as good as an open ear headphone can. It definitely feels like I got away with something.

Nice pair
These are the first pair of clip-ons that doesn’t hurt my ears even after few hours of wearing them. Quick and easy Bluetooth connection. They stayed on ears and sound quality is good enough for during exercise. Good battery life and charging is fairly quick. Con: these don’t work very well when being on the phone. Very difficult to hear the other end (almost like the headphone considers the sound coming from the other end as noise and cancelled it). And when leaning my head to one side (either side), sound would disappear completely (sound does come back after both earpieces are back on same level) Keeping those since they work well around my ears and doesn’t hurt.

Best open ear I’ve tried!
Haven’t tried Bose because of the price. Don’t need to now. I can only use open ear buds for ear infection reasons. Tried bone conduction of all types and open buds of all types and these are legit. Great sound for music and calls. Fit comfortably. Great price for the quality. Charge quickly and has a charging indicator light. Function wise I’m uncertain. It’s hard for me to get used to tapping as I use them while delivering in a van. Also, wish they sat just a little closer to my ear canal because when I push them a millimeter closer they are much louder. My ears are probably considered medium or leaning towards large. Great product!

Trash
These are trash, the headphones rarely connect to the case. They are not charged when I need them, they stay connected to my phone when they are in the case and I have to turn my Bluetooth off to disconnect. It won’t let me leave zero stars.

Monster (China)
They are not made by the American company monster. Not sure if they're a subsidiary in China. They sound good but the battery doesn't last long not as they claim. It says it should last 8 hours. I have them on for less than 8 hours and I barely take any calls. And it's already almost dead within five.

Update final review with replacement: Battery issue after 2 months of use
The clip on earphones for a couple of months was awesome! And I really did love them at first. But after those couple of months of use, they slowly declined in battery life, leaving you to have to charge it more frequently. So not sure if i got a defect. But other than the battery issue they are good. You can hear great when listening to music, or talking to someone, and they can hear you back, and you can hear yor surroundings while wearing them. I would give 5 stars if it wasn't for the battery issue after a couple of months using them. UPDATE: The customer service of this seller, for the clip on earphones, has reached out to me, and their customer service is outstanding!! They said they wanted to make things right with me and let me choose on what I wanted to do. I asked if I could get a replacement pair of the clip on earphones and they said they would be shipping it out. As soon as I receive the replacement pair I'll do another update and hopefully will be able to give them the 5 stars. If any of you are having problems with any of their products please reach out. Their customer service is outstanding! Final update: I received the replacement clip on earbuds today. The packaging looked great, no damaged that I seen. I haven't tried them out except for today. If anything changes within 2 months (reason 2 months is bc that's when the original pair started having charging issues.) Of me using these headphones I'll definitely submit another review. But everything seems good so far. Thanks Monster company for the replacement and working with me.

Not all that
Been about a couple months since used quality not the best, for some reason volume sounds is very low even when you have it max, comfort is good you don’t even notice that ur wearing them, connection good battery life only last you 2 hrs at most and one side stop working after two months of use.

Great for office jobs
Not my favorite set for pure audio, but they do sound really good and I like being able to directly hear my surroundings.

Great pair of buds
My preference is traditional in ear buds. Though I would give these new style a try. Love them, barely feel they are on and sound is quite equal to Bose, which is what my wife prefers. Would recommend these to anyone who grew up with in ear buds and wants great sound and not sacrificing comfort.

Good product not so easy to operate.
The touch control is very sensitive and difficult to manage properly. Sound quality is very good. They stay in your ears well even when exercising.

Compact and solid build!!! Totally worth the money
Amazing! Bought on sale. Although it is not the authentic North American monster brand…. It is 100% worth the money. Like with all open ear earbuds, don’t expect the biggest base but the sounds nonetheless are great. I own studio Dr. Dre headphones and I’ll be using those for the gym but these will basically be used for everything else. The case and the earbuds are so compact. I love these. I’ve owned these for less than an hour and they got me so excited that they are worth writing a review for already. They are so light, they don’t joke around when they say you don’t even feel that they are there. Overall builds quality feels great and I’ll be updating this review if anything significant happens.
