The MM 100 Stereo Bluetooth Wireless Headset from Sennheiser is a high-quality wireless headset that allows you to enjoy your music with virtually any Bluetooth-enabled device, as well as make phone calls with Bluetooth-enabled multimedia smartphones.
The headset has a behind-the-neck design and foam ear cushions for a discreet look and lasting comfort. Large drivers and Open-Aire acoustics deliver detailed, natural sound. The integrated microphone is invisible and out of the way, but provides excellent vocal pickup.
Controls for volume control, track skip, play/pause, and answer/end call are conveniently built right into the headset, giving you full control without having to remove the headset. The headset charges via a USB connection, and a wall adapter is included.
