I didnt want Bluetooth or similar "Wi-Fi" technology because of connectivity problems that can often affect these, I just wanted something simple and straightforward that would transmit the sound without dropping out, and without needing constant pairing etc. how do I put it? Soft, squishy. Still though, I managed to get dust, and I mean a lot of dust, pocket lint and dirt in my case. I had them working once but when I tried to use them again it said unable to pair and that I had to redo it. I got these for my 3 year old in her normal size 10 she wears in sneakers (she?s more like a 9 in sandals, in sneakers with socks I size up) and they fit as expected! Je mattendais à quelque chose de plus robuste. Proved very useful on numerous occasions since I bought it. They are way too big and not adjustable. Additionally, the microphone was extremely quiet and with people in my discord turning the volume up to 200% they could barely hear me, windows microphone volume was max and there was no way to increase the volume output. They looked extremely cheap, and my fears were confirmed when attaching them to the headphones.
