I bought 2 pair of new headphones from Amazon recently. They are Turtle Beach's model Ear Force X2 headsets.
The primary purpose of these headsets is to connect them to an XBox 360 controller as the microphone source. What happens is the headset's base station, while connected to the Xbox, transmits the game audio to the stereo headset, and the headset's microphone connects to the controller to send Live chat sound back to the game. It's a pretty nifty idea, but not why I bought them.
My purpose for buying the headset was that the 2.5mm plug on them would fit nicely into the jack on my office's cordless phone. My expectation was that I could hook the headset to the PC to listen to music, and then also take calls using the headset by connecting the dongle wire to my phone. Non-monaural audio playback for phone conversations would alleviate many of the problems I have in my office regarding ambient noise. But it seems that my plans have been squashed by poor (or cheap) forethought....
