Review: 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 desertcart 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 desertcart/ebay the only product of its kind I found. Recommend
Review: 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
*by U***K on 10 August 2016*

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.
