FosPower (3 Pack) 3.5mm Male to Female (4-Conductor TRRS-24K Gold Plated) Auxiliary Stereo Audio Jack Adapter for iPhone, Smartphones, Tablets, Speakers, Microphone & Card Readers

I purchased these because I keep my phone and iPad in protective cases which make access to the headphone socket difficult for the jacks on most auxiliary and headphone cables.They have solved the problem as the FosPower jack adaptor is slim enough to fit into the socket on both devices in their cases. This means that I can listen to audio in the car for example without removing the case. Bought three so one left as a spare, but the build quality of these seems pretty good.A simple little idea but well executed by this product.

Exactly the kind of adapter that's needed for headphones with narrow opening and phones with thick cases.After the headphone cable for my Oppo PM3 planar magnetic headphone was damaged the replacement standard cables were too wide and needed manual modding to the ends which made them fragile and aesthetically displeasing.This adapters however fit perfectly and opened up the use of any audio cables.Great price and quality

As with many people, I needed a way to use both my daily and lounge headphones with my cased-up iPhone, which restricts most, if not all, of the headphones of even a year or two ago from being able to negotiate the jack cutout depth of the case.These jack adapters are very well made, solid metal with gold connection, fused completely with the casing. The jack point fits as easily into the iPhone jack as easily as any normal headphones, but it is slim enough to get through the case cutout, which is what I wanted it for.I also like the fact that when putting your headphones into the adapter there is a nice solid click, so this tight connection combined with the slightly looser connection into the phone will go some way to preventing the phone from getting ripped out of your pocket if the lead is tugged hard on.I wouldn't call these real gold plated though, as just through a couple of months usage the gold on the jack has actually all come off and is now completely silver, so the "24k gold plated connectors" claim is dubious.

Fantastic product. I bought it to help activate a low impedance head or ear phones below 50 Ohm, using the LG V series Quad DAC to sound louder and cleaner, which no other smartphone can match LG V and now G series phones. Works like a charm, once you've tried it, i bet you'll hate all other phones sound quality, using 3.5mm jack. Tried the Note 9 after i just recently purchased it, coming from LG V10, and quickly sold it and bought the V30 and my smile was return immediately. It works well with protective case on.

Perfect for the job

Bought this to use with my iPhone in an official apple smart battery case. The adapter is not long or slim enough to work correctly. If your hope is to use it with the smart battery case, do not buy this product

Hoped this would work as a trs headphone to trrs mobile device, but NO!THE TRRS PLUG WON'T EVEN FIT COMFORTABLY INTO MY TRRS MOBILE DEVICE,let alone convert it to a regular trs headphone. May have just found a Rhode that will.

Can't give bad rating but this doesn't work for me. It does NOT fit Anker IPhone case therefore useless.
