Review on Enhanced Version: MEE audio X6 Sweatproof Sports Bluetooth Wireless Earphones with Headset and Earhooks – Designed for Running, Gym, and Workouts by Karen Lewis

The sound is very flat but I was fine with that and knew before I bought it. Also the equalizer will only do so much. If you're looking for deep, meaty bass, this isn't for you. My main complaint is the dismal battery life. They claim a battery life of 9 hours on a full charge, but I have yet to get over 4.5 hours. Also, when connected to a computer, the charging time takes forever. Almost 4 hours to charge and then you have something more than real use. I love the fit and ease of the device on my head but I would never buy this pair again just for battery issues.
