FosPower 3.5mm Male to Female Auxiliary Stereo Audio Headphone Jack AUX Adapter, 4-Conductor TRRS for iPhone, Smartphones, Tablets, Speakers, Microphone & Card Readers (3 Pack)

these have worked great and provide what I need. I use them to make hooking up my motorcycle ear plugs to my comm unit, and they work great, and there is no additional distortion or static.

Just what I was looking for. I bought this 5 pack because I have numerous devices and cables that have thick cases and large cable connector heads. I'm very happy with this product. I've tried them and they work on everything I have. I've tried the FosPower adapters on my iPods (3 different types), Kindle Fires (3 different ones) and iPhones. All my devices have larger/thick cases on them and the FosPowers fit and work just fine. One reviewer mentioned they won't work on "ANY" Mophie Battery Pack/Case which isn't correct. Another reviewer stated it doesn't work with a iPhone 6S+ which I can't speak too. I have a iPhone 4S and my wife has an iPhone 5S, both have Mophie Power Packs, and the adapters work great. The iPhone 5S with Mophie has a deep recess into the headphone jack but just a little pressure will seat it. The adapters are well made with solid construction and quality materials. I wouldn't recommend having your device in your front or rear pocket with an adapter inserted if you're going to sit down. I could see it potentially breaking since it is a rigid adapter that sticks out about 3/4 - 1 inch after inserted. Nice product and worth every penny...

I used these adapters to fit my Galaxy a15 cell phone and some other media devices. The adapters fit very well and did not have any noise distortion involved with using them. This is a high quality item that I would really recommend.

Awesome fit especially when you have a phone case that doesn't let the regular jack that comes with headphones fit. Functions the way it needs to and the price is good. Sound quality would depend on your headphones but good so far.

I purchased this extender to allow me to listen to my Custom In Ear Monitors on my iPhone with the Apple Extended Battery Case. I was so sad when i bought this case and realized I would need to buy a new cable for my phone to work with it. Well, this was a MUCH better and cheaper solution! There is a slight bit of resistance from the case due to the length of the thin portion of this connector. It is a perfect fit, but it's really close. Right before it inserts into the headphone jack, there is a tiny bit of interference with the case. It's not enough to cause any issues, although if you pull lightly on it, you can feel that an "outward force" exists on the extender due to the case. I also tested the sound quality using this extender vs no extender using Jerry Harvey JH13 $1200 in-ear monitors... if there was sound degradation, I would absolutely hear it. This does not affect the sound in any sort of noticeable amount. If there is degradation, it is not audible to the human ear. This was a big relief for me as an Audiophile. I used The 1975 - "I Like It When You Sleep, For You Are Beautiful Yet So Unaware of It" as my test track. Great frequency range to listen for any degradation and all checks out! All this said, it works well, it IS compatible with the Apple Extended Battery Case.

Handy when you need them so I keep them in my video bag at all times.

Works great - This extender allows me to listen to my streaming music all day using my unlimited cell data plan rather than using the company WiFi. Before, I couldn't plug my computer's stereo speakers into my phone because the computer speakers have an L-shaped 3.5mm connector. With the case on my phone, the L-shape wouldn't allow the connector to insert all the way. Now I'm happy as can be because I get great sound out of my computer speakers and it's easy to turn up, down or off when I'm on a call or in meetings. The connectors appear to be made of quality materials, though I admit freely I'm not any kind of an expert in this area. I never get any crackling or feedback, and I always get a very good, solid connection every time I plug into my phone's headphone jack. I told my husband about my solution and now he does the same thing to listen to his favorite streaming audio during the day.

The item itself works well. The case on my iPhone has cutouts that don't allow normal headphone jacks (especially L-shaped) to connect properly, and I've gone through several pairs of headphones, as the case bends the jacks over time. I searched for a new case, but could never really tell whether the cutouts would be any larger. This adapter, however, fits perfectly, and I wish I could have given it 5 stars. The only reason I didn't is, straight out of the package, it looked really beaten up. It's scuffed, scratched and marked all over,and the lettering on the item is scratched off in places. I'm fairly certain FosPower sent me a used item, though it did not state anywhere in the description that I was purchasing a used or refurbished product.
