Do you get tangled up in your headphone cable or pull your computer off the desk because you forgot that you are connected to it with your headphones? Some of my co-workers do and asked me about wireless headphones or headsets for use with Skype and music or streaming web audio.
Wireless headphones have until recently costs over a hundred dollars, whereas, a USB wired headset from Logitech costs $30. Mono Bluetooth headsets sold for use with cellphones might work, but they are mono and not so suitable for music.
Fortunately, Staples (which I cannot find now) was offering the Jabra BT620s Bluetooth stereo headset for $30. You can get it for $38 on Amazon. These headphones had cost over twice as much at $78 or so. Motorola sells comparable headphones for $99.
I ordered the Jabra headset and have tested it out with my MacBook. It was fairly easy to pair with the headset. It took a couple attempt, but once it was connected it worked very well.
