VENTION 3.5mm Female to 2.5mm Male Audio Adapter Converter Premium Quality Headphone Earphone Headset 2.5mm to 3.5mm 3 Ring Jack Stereo or Mono(2 Pack)

It does the job for me. Also it's not expensive.

These work perfectly, as they should. My particular use-case is also kinda weird, and I'm happy they they work for what I need them to do. I got a new pair of headphones recently and the detachable wire which connects to them splits off into the Left and Right channels, each connecting into its respective Left and Right side of the headphone. The connections on that end (usually) are 3.5mm. After a short while, this wire became faulty, so I needed a new one. I bought a new cable of the same type without realising that the connectors which would plug into the headphone were 2.5mm instead of 3.5mm. After a bit of research, I realised that having a 3.5mm jack on the end of this split connection is unusual, and the only option available to me was to buy one from the American Amazon, which would have cost me an arm and a leg. I found this product and thanks to their thin design, they fit perfectly into the female 3.5mm input on my headphones and the sound comes through perfectly as it should. The colour is a reflective silver/black which is fine as it fits in with the rest of the headphone pretty well and doesn't add much length at all to the wire. Buying these as a quick fix has actually saved me a lot of money and allows me to listen to my nice headphones in peace.

Robust, does pull out rather easily though.. Not sure if these or the socket at fault.

Hard to find items but do the job perfectly. I would have liked right-angled versions but they seem unavailable. But happy with my purchase

dosen't work at all, total scam

Great product , speedy delivery

As expected

It seems well built and it's not huge like other similar adapters. I might end up using this more due it's small form factor. I haven't thoroughly checked sound quality but for the use I have for it, it won't make much difference.
