Bluetooth headsets have evolved quite a bit since the last time we had this discussion, so we're curious what you're currently using to make work a wee bit more bearable? No need in keeping secrets, right? Speak out in comments below!"I need a headset which can block out the background from a busy office. I'm talking repetitive noises such as drilling, background chatter, keyboard clattering, computer fan whirring and the endless static from our building's air conditioner. I would love if this headset had a fair to good quality of sound for MP3s, and it would of course have to have a good microphone for IP phone telephony and Skype. If it didn't look like something from Radio Shack that would be a bonus, and if the microphone was a bit discreet for street and airplane use that would be an added benefit. Lastly the connection to a workstation could be both USB and Bluetooth, with a preference for wireless. Thanks!"
