Decent helmet, rather heavy. To pair the Bluetooth, search YouTube, as the manufacturer's instructions are lacking. Once you do finally pair it, audio quality is that of an old transistor radio, very tinny, no base. I've read other reviews stating this is a quiet helmet, but my experience is that it's not any quieter than average.One thing I find annoying/cumbersome is the microphone boom, when you put the face shield up, then back down, it hits the mic and bends it down under the face shield, and it takes your other hand to hold it out of the way/adjust it.The tinted sun visor likes to move up and down, as well, doesn't stay locked in position.I didn't use the helmet much right after buying it, if I had, I would have returned it.
