A month later, this helmet is perfect for me. It is very, very small and incredibly light! But as a certain brand of laundry it is "small and mighty", the bass is present but does not stifle the spectrum, just as acute, lovely. The remote control is compatible Android and Ios, which means it has no volume control and a multifunction button only + microphone. Only drawback in this pretty picture: the cable is very (too) short, which can be very disturbing for adults. Recommend!
