This impossibly small (1.5-inch, 1/3 ounce) Bluetooth headset is the perfect compliment to slick phones such as the Razr V3. Jabra did a nice job not rushing it to market merely because of its irresistible size. You WILL forget you're wearing it; it's that comfortable. Great with sunglasses, too. It's loud enough for most environments (car windows down...NO). It sounds surprisingly good for both incoming and outgoing calls, although there's a faint hiss at all times that I don't get with the new Logitech Mobile Traveller headset. While sibilants were a bit exaggerated on the Jabra, it sounded clearer to people I called than some other headsets, with less of an "underwater" sound. You can charge it with the included stand, or directly from the charger (awesome), or directly via included USB cable from your computer. This Bluetooth 1.2 headset works with virtually any Bluetooth phone in both Handsfree and Headset profiles.
