ComputerAct!ve (dead link) reviews TRENDnet ClearSky Bluetooth VoiP Internet Telephony Kit and concludes with overall rating of 3 out of 5 that Skype devotees will find the ClearSky undoubtedly appealing. However, those who just make the occasional call should probably save their money and stick to using a headset. Good point is make and receive Skype calls wirelessly, while bad points are expensive, average call quality and PC must be on.
Tech Digest concludes that It costs £78.99 here so you’ll be paying a bit of a premium for the Bluetooth, but it is the only one on the market with a decent range. If you’ve got a number of Bluetooth enabled pieces of kit, AND use Skype a lot, AND tend to keep your computer on, go for it.
