Clip-on microphone

[caff]

Is there a decent clip on microphone out there?

I have a nice pair of senns HD650's so no need for headphones but I just want a simpe (but decent quality) clip on mic to make a kind of gaming headset.

Tie clip mics/lapel mics are quite common and sometimes fairly cheap, but would probably need modifying for PC use. I haven't seen a tie clip PC mic before. Also bear in mind mics mounted there require a lot of EQ to get a clear sound as you only really pick up vowel sounds.
