Good bluetooth speaker hat.
Its comfortable to wear and sounds just like headphones, I have to turn the volume up a bit louder than on a pair of headphones but apart from that its just the same.
Connecting and disconnection of the bluetooth is the same as headphones too.
Its a nice quality hat and keeps you warm, I would probably like it more if the speaker boxes were slimmer but they sound so good that I will use it anyway.
Usb charge which lasts quite a while.
