Hehe Steve, I already soldered new headphones for my mobile phone...
I use a very cheap Hama CS-499 headset, but i use only the mic, for the ears I got additionally Philips headphones. The Hama is so tiny, that it's no problem to wear two headphones at the same time.
Btw: Can you compare my sound to somebody else in mumble? I don't know if I'm loud, noisy or too low...
I like Blinky's voice in mumble, he must have a good headset or spend hours in mumble set up and audio post-processing.
