Don't waist your money on this one. The sound is clear but is not loud enough to overcome the chatter of people around you, or the sound of the road on a bus, WAY TO WEAK! The battery is not replaceable and does not last over an hour per charge and after 6 months you barely get 20 minutes out of it and it won't hold a charge for a day. The earphone are not bendable enough to match your personal preference of a fit inside your ear You also can not find a Bluetooth plug-in adaptor which will help you listen to your computer unless your computer comes with stereo Bluetooth. Other than that, I have no complaints. But shoot, that would be enough to scare me away.. even though these just happen to be the best on the market.. WHERE HAS OUR TECHNOLOGY GONE? I am waiting for a better system which addresses these issues. 1. Loudness, 2. Replaceable Battery 3. Bendable earphones, 4. Stereo Bluetooth Adaptor. The Motorola people seem to be a little careless here.
