A star for the quality of manufacturing and another star for the quality of the product (just the sound, microphone), after that my god helmet hurts my ears, you CLIP head, after 10 minutes of utlisation I have a sore skull and yet I do not have a big head.
I already have a PC350 and PC360 one of the same brand, I would buy it to use on the move for its small size compared to the other two but I think it is missed. I return the product.
