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 Trent Kraft

Everything worked great while it lasted. The price was right, but it connected directly to the phone: it's said to have a long cord, but half the length is occupied by a coiled section with a very stiff coil, so it'd either take the phone off if I pull the table too far or take the headset off my head; small callus, you couldn't hear what you said in the mouthpiece; In the end, it lasted only a year and two weeks (bought on May 4 - began to irritate on May 22 of the next year). If you are looking for a cheap short-term solution this might work for you, otherwise find another product.
