What horrible customer service for a $250 headset. Ill modify review if it doesnt last. At maximum volume and light on, the battery life is 4 hours. A few things I dont like, is that the squeeze on part that holds your bike(not included with this), could be wider and a bit softer to attach to your bike(maybe rubber or soft cloth), but you can add the cloth if that bothers you. So I bought it lol. It also announces when the mic mutes and unmutes. If you really want to use the carabiner, Id also use a thick black rubber band to ensure the case stays closed. I have moved gym equipment to new house, also long couch, construction materials. Might be fine with thick socks. Perfect touch for my modern bathroom.
