Headset with Wheezy

[Lisi Reisz <lisi.reisz@gmail.com>]

I am proposing to buy a headset for recording with Audacity and Wheezy. The 
earphones will presumably be fine provided that sound is working, but I am a 
bit worried about the mikes.  These two Sennheiser headsets look promising, 
but I would value comments:

In particular, does anyone know whether the mikes work OK in Linux?  
(Audacity, on Wheezy with Trinity DE.)

Thanks,
