Well... I have cancelled my order for the Archer as it never materialized when promissed and I got tired of calling a company that never naswers its phone.
I have gone and done the crazy thing and I ordered and received the Gennum nXzen 5500, a very expensive $159 headset. (
www.gennum.com) It is supposed to have just about every bell and whistle a headset can have including their FrontWave Noise cancelling technology that uses a two mic array and DSP. I have only had it a few hours and I can tell you that it's noise cancellation is awsome! It also comes with a graphics EQ capability and can connect to both a Bluetooth Headset and an MP3 player. I will be doing a complete review on the unit during the next week.
