The Underscore Archives

Anyone got a fave headset, for the likes of Skype? Is USB the best bet (for
use on mac with no audio input) or is bluetooth worth it (presumably
batteries required in the latter). Decent quality second-hand suggestions
that might end up around the 20 quid mark on eBay would be especially
welcome. Mono or stereo would both be fine. Or maybe there's such a thing as
a wearable mic that I can pair up with existing phones?
