Motorola original hands-free stereo earpiece (HS120) is both stylish and convenient. Listen to music in high-quality stereo or handle calls. In-line microphone and answer/end button for handling your calls. Please note that if your phone requires a hands-free adapter to use this 2.5 mm headset or if your phone is not capable of stereo sound, then this headset will produce only mono sound rather than stereo.
