Morning! I do not think the Telex you are using is certified (I could be wrong) and I have noticed a HUGE difference between my uncertified desktop Sennheiser e835 with Andrea or Plantronics USB pod (that still performs acceptably) and my certified Andrea headset. After setting up profiles on several mics, it appears that it is far more important to have a high quality desktop if you cannot wear a headset, but that is just my own experience. Hope that helps a bit! Valerie Maples Intel Core 2 Duo 2.16 GHz iMac 2 GB DDR SDRAM OSX 10.5.2 Sennheiser e835 Andrea USB pod On Apr 20, 2008, at 12:30 PM, Kevin O.
