The FREETALK Everyman USB Headset is a super wideband audio headset that has been built to enhance the Skype experience. The headset features a unidirectional microphone, neodymium speakers, and works with USB (for audio recording and playback) and has detachable 3.5mm jack for using the headset with an MP3 player. The foldable design allows for easy storage in a laptop bag.
I've tested it on Skype, and use it all the time to listen to music. The sound quality while listening to music gets top marks. Listeners have also commented on the great voice quality received on a Skype to Skype/phone call.
The headset is relatively inexpensive, at under $30. But don’t let the price fool you, the sound quality is better than comparable headsets at much higher prices.
