[Asterisk-Users] USB headset recommendations

[Ken Alker]

I'd like to get some feedback from users of USB headsets as to what they 
like/dislike about the unit they own (manufacturer/model number).  I'm 
looking to buy some.  Is there already a thread somewhere or a review (I 
tried to find one with no luck), discussing this topic?

Any advantages/disadvantages to using a USB headset over a regular headset 
slaved off the internal sound card?

Are you using yours in a call center environment?

As an aside, do all USB headphones have built-in sounds cards?

If so, are the built-in cards always full duplex?

Any other hints or ideas?
