I wanted a wireless headset to prevent the wire from the headset does get caught all the time for long walks with my dog. The aesthetic aspect is also important, I finally opted for this helmet which suits me perfectly.
Fairly easy to use, very easy to connect to different devices we use (Samsung S4, Ipod Touch), rather light and with a sound that I like, I do not regret my purchase.
Only unknown, the duration of the battery charge. Until now, I never fell short.
