Keep your ears open but still hear calls with clarity when using the OpenComm2 UC Bone Conduction Wireless Open-Ear Headset from SHOKZ. The open-ear design of the OpenComm2 UC lets you remain safe and aware of your surroundings, and makes it more comfortable to wear the headset throughout the day. In order to offer that and still achieve clear calls, the headset uses 7th generation bone conduction technology and PremiumPitch 2.0. Medium and high frequency sounds are equalized for distortion-free audio. To make sure you're heard clearly on the other end, various technologies are employed with a rotating built-in boom mic.
