Bose has more than a few Bluetooth devices in its line. Last month we talked about the new SoundLink mobile Bluetooth speaker. Bose has announced that its new Bluetooth headset called the Series 2 has now launched and is available for purchase online. The headset has noise cancellation tech inside and has a mic that rejects outside noise like wind so the caller can be heard clearly. There is one strange thing about the Bose headset though; it comes in dedicated right or left versions.
