The Sport Bluetooth Earbuds produce over five hours of continuous high definition stereo sound for people with active lifestyles and fit securely with an adjustable band to correctly tension them. Another excellent feature is a built in microphone which provides the option of making and receiving phone calls and even switching between calls. This is a superb function for people on the move or exercising who need to catch up on work or take calls without stopping. Sport produces such exceptional sound quality that they can be used instead of regular headphones while relaxing and they have their own carry case complete with a micro USB cable for charging. .
