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)

Good when jack is recessed and cant get plug in all the way, this will solve that problem

I used this product when I needed a slim aux jack to fit into a small space on a phone case with an older style aux cord that was fat and simply wouldn't fit with the phone case. This product remedied that issue without trouble. Would recommend if you're experience a similar issue!

great

Worked good for extending outlet on phone for square card reader.

I have a portable speaker that I want to be powered an at all times and also use the available AUX jack for the audio, instead of Bluetooth. However, the way the speaker was designed, I was unable to plug in the AUX cable and the power cable at the same time, because they are too close together. This FosPower 3.5mm male to 3.5mm female jack gave me the space I needed to raise up the audio cable and because it's so slim, I was able to plug in both cables and accomplish exactly what I wanted, with no noticeable affect on the sound quality. Thank you for providing me with exactly what I needed.

This is used to get past the thickness of your device’s rugged case. You must accept that it is a wear item and will need to be replaced. Anything that sticks out and is touched by people goes bad. I like how it comes in a multi pack so it lasts mom longer

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.

The build quality is fine and they look great, but they don't work for the purpose intended. I was seeking an adapter to plug through an iPhone case so that I could continue to use my high-end headphones that have a right-angle male plug on the cable and thus don't go far enough into the czse to fully engage with the jack on the phone....and I thought these adapters would work...one for office, one for car and one for briefcase. Maybe I misunderstood the dimensions. Anyway, the barrel on the male end of the adapter is too large in diameter to go through the hole in the case -- and the hole is pretty large; larger than many others. So, anyway it won't work for the intended solution. I just tossed them in my "accessory drawer" with other cables & adapters...maybe I can use them for something else in the future.
