Review on Hands-Free RJ9 Headset with Monaural Mic and Noise Cancelling for Avaya Nortel, Yealink, Ge Emerson, VIOP, POE, NEC, Mitel Office Desktop IP Telephone Phone - Includes Extra Cushions by Dawn Campos

This is SO STUPID! I ordered it based on the good reviews and the fact that it would work with my office phone and was adjustable. First, there's no volume or mute button on the cable, and the picture isn't what I got. Second, the headband is not regulated by AT. EVERYONE. But the microphone doesn't work at all! He came with a card asking me to call a number instead of contacting Revain with a problem but of course no one answered the call, I left 7 messages and called 15 times and they didn't answer! DO NOT BUY THIS! Better buy!
