Review: work as designed. - 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.
Review: Just what I needed and glad I picked these... - 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.
