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)

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.

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...

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.

Very well made, slick look, durable 3.5 mm Male to Female headphone jack. Affordable. Fits perfectly. Sound quality is great! It comes 3 in pack. I can give one of them to my family member.

Nice to have in case I need it...

We have purchased dozens of these adapters and have had a big problem with them breaking off in our iPads, ruining them. I am going to look for stronger ones to replace them.

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.

Works as designed. Just perfect.

Very good quality, i’m using with my headphones sony mdr-100aap.

Je suis ravie d'avoir trouvé ce produit que j'ai longtemps cherché sans succés. J'ai un Samsung S7 muni d'une coque de protection et je me suis offert un combiné rétro. Problème : le jack ne passe pas la coque de protection. Au début, je n'ai trouvé que des rallonges, avec parfois le même problème. Et comme je n'avais pas fait attention, la rallonge avait 3 pôles et le micro ne marchait pas. Mais cet adaptateur est vraiment parfait. Il est extrèmement fin et possède 4 pôles ce qui est important pour le micro. Pour savoir ce qu'il vous faut il font compter le nombre d'anneaux sur le jack : - 2 anneaux = 3 pôles (audio stéréo ...) - 3 anneaux = 4 pôles (audio stéréo, micro ...) Merci d'indiquer si ce commentaire vous a été utile.

ケーブルが着脱式のヘッドホンの中に、脱落防止のためバヨネットロック方式を採用している製品が結構あるが、困ったことに何れも形状がメーカー毎に異なる。 かく言う私自身は、Marantzのヘッドホン（MPH-2）を利用しているのだが、そのバヨネットロックに適合する純正のコイルケーブルは販売されていない。 こうした細見のコネクタを間に挟み、バヨネットの突起部を回避することで、例えばATH-M50x用やV-MODA用に作られたものでリケーブルが可能となる。 多様なリケーブルに対応できるるほか、ヘッドホンのコネクタ部を摩耗から保護することにもなるため、一石二鳥の優れた製品であり、工作精度も比較的高いように思われる。

Absolutely ideal. Our headphones have a 90 degree plug which isn't always best. These are sturdy and well made
