This is my first full face helmet and I love it. very lightweight and comfortable to wear. When it arrived, I couldnt wait to install the blue tooth set up which was pretty easy to do. There was a little juice in the battery to I connected it to my I-phone and tried out the music. one side was crystal clear while the other speaker was static. I contacted the seller about this and had a new speaker set up in just a couple days. The customer service was excellent and before I knew it, I was riding while listening to my "ride me" play list. This is definitely a a great value product for the money. I'll be purchasing another one for my wife so we can use the intercom feature and be able to talk to each other while we are riding. Excellent product!!
