Review on Plantronics BackBeat FIT 350: Stable, Ultra-Light, Sweatproof Wireless Headphones for Workouts - Grey by Kofi Wills

Button controls are non-intuitive and currently not configurable. For example, to skip a song, you need to press and hold the volume up button for 2 seconds. This slows down song skipping. Also, you cannot go back to the previous song, you can only restart the current song. With dozens of other Bluetooth headphones, press the center button to switch between songs. Also, the control knob dangles a little awkwardly behind your ear, it's not quick access as it moves around so you'll have to reach around to find it. Do not change settings for sound quality, fit and comfort are fine
