Looking for a decent headphone with mic for my CVP 309 use. The PC gamer / internet units aren't what I have in mind. (They require external DC voltage to operate.)

I have found the Sennheiser HMD 280 which might work just fine, though they don't seem to be generally available in the USA.

The CVP requires a dynamic mic with a 1/4" plug. Do any of you use headphones with mic as part of your system? I would appreciate any recommendations. Thank you.
