For its price there are two things that are really unfortunate is: - Its bearings, small and rather hard they are quickly uncomfortable (I have personal changed for those of another helmet). - The cable is only dedicated phone for Iphone and iBidule, nada for Android or another. Do not rely on luck or app, SA ONLY WORKS IN IPHONE. The sound passes but the remote remains inert.
If the headphones are robust and practical as it bends and becomes flat, the sound is very good and well balanced between bass, midrange and aigu.Le being able detached the cable jack and really a plus. The helmet is well designed but not upgrade its level ergonomics and it is a pity.
