Bought to make speakers/cables work with my phone case
I bought a new case to protect my brand new phone but unfortunately access to my headphone port was affected. None of my aux/speaker cables fit through the case. I bought these as i couldnt replace all the cables. They came promptly with amazon prime delivery. Feel like good quality and aesthetically pleasing. Worked well with my speakers with no audio distortion and fits well with my case. At £7 for 5 pieces i think they are reasonably good value and on amazon/ebay the only product of its kind I found. Recommend

Best adapter for narrow headphone jacks
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

Fits perfectly through an iPhone 6 case jack cutout – but dubious gold plating claim
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.

Small useful connector
I bought it so I could connect my earphones to my phone, as it has a robust protective cover. It connects and works fine, good sound quality. So far very satisfied with my purchase.

Fantastic product. Gold plated 3 pieces.
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.

It's good quality long lasting extension.
Edit: The first one I received was faulty. I bought a bendable extension as a replacement (lasted a week) and then I bought 3 pack of these ones again. It has been working fine for 5 months now. Yay! ___________ The aluminium (?) outside part kept on sliding off revealing insides made of white plastic. I thought because it's not bendable it's going to last longer than regular cable-made, bendable extension but instead, when I dropped my phone while using it, it bent in two places (both in the plastic part and the audio jack part).

Faulty product
One of the plugs snapped in my sons phone and the tip was stuck it took about a hour with some tweezers to retrieve it I'm still working out how to get a replacement off amazon as the product is good and may of been a one off as the other 2 are going strong still

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...

avevo un cavo per cuffie professionali che era strutturato in modo che il cavo aveva il maschio del jack in uscita piegato di 90 gradi, peccato che così non potevo inserirlo nel cellulare perché con una cover molto fine non entrava il jack perfettamente, grazie a questi adattatori sono riuscito a inserirlo senza problemi, nessuna perdita di qualità del suono. Molto soddisfatto

These are exactly what you want them to be. Great quality, fair price, and they work to fit your jack in all those piss poor designed case, covers and wraps for all your gadgets that failed to take in to account that you may actually use it. They do not hamper the quality of the sound in any way, they are exactly what you want! BUY THEM!
