Just got them this product I am bought 1 month ago it's very fack product the really very bad.
This is heavy make my head hurt, I can hear music. Stick with Bluetooth earphone this sound quality is not good. It is nothing like say it will be. The sound quality is horrible, the glasses are uncomfortable to wear. My look a fool wearing them.
I am told this packaging very poor.
The frame is quite bulky, much more bigger than a regular sunglasses due to the bone-conducting, but do not bother me really much.
