I go several times a week about 12 km or about 35-40 minutes on the work and like to listen to Radio.Was I do not like is clutter. Therefore, a Bluetooth headset was needed. After reading some reviews I landed at Plantronics and have to say I have not regretted the decision. The Akkut holds about 7 hours, and thus a good week which is totally ok for me, besides, I can do it at any time at home or charge to work. When you turn you get told the remaining term, the sound is quite enough for me. Of course one must not expect miracles. I have only the challenge that I fight against the wind and therefore must provide the transmission still relatively noisy. Also acts listening to the radio the headset cord as an antenna. But is not a problem - I simply me an old headphones attached to the handlebar, the I connect while driving to my smartphone (Sony Xperia T) and then can listen function on the Plantronics Radio via "Throw". Previously nich never had dropouts when driving. A deduction of points, there is only because with the handset but now and then slide from the ear. Overall, however, a strong buy recommendation.
