Unfortunately have emerged over time (use for about a year) also a few problems. Since the claims are different, I list only on here without Rating:
- Microphone sensitivity can not be adjusted, especially with jet helmet-use or open visor therefore do have to be prepared for wind noise in the ear
- Voice Control possesses some inertia, it is best to blows before spoken briefly into the microphone, otherwise go the opening words lost. After ending the call, it often takes a small eternity before the automatic switch off. This is particularly annoying when incidentally runs music
Theme music: the issues raised by other reviewers gripe that the music playback is too quiet, I do not share. (But also depends on the helmet) However, the music volume is not controlled along that needs to be done on each player.
- Music playback is not possible without radio unit. Ie who wants to use the already built-in headset multi-day tours as a solo headphones, even the radio module must be charged in addition to the player ever. This is bad if you are camping.
- Charging during travel via 12V socket is not working. (If someone has found a solution, please contact !!)
- Battery can not be exchanged
- The headphones of the headset are not bad, but not outstanding. Unfortunately, they are firmly connected and not interchangeable.
- Built-in radio completely unnecessary because unusable
My conclusion: For day trips for two good and in the price range currently no alternative headset with (almost) everything I need. For the longer tour outside the hotel accommodation unfortunately unusable because the permanently installed battery can replace neither during load driving, even by a separately charged spare battery. (However, for a total of about 210 can be obtained at Cardo two spare radio modules plus 12V chargers ;-))
