Keeping in touch when you're on the move can be challenging. The Bose® Bluetooth headset Series 2 meets the demands of on-the-go communications, from crowded terminals to noisy traffic. It's engineered to react automatically as noise levels change, allowing you to hear your end of the call better. Plus, an exclusive noise-rejecting microphone system helps your caller better hear you above both noise and wind. The Bose® Bluetooth headset is compact, light and well-balanced, and now you can choose between right- or left-ear versions.
