The Samsung WEP480 Bluetooth headset is highly fashionable and highly functional. Carry on amazingly crystal clear communications anytime with its dual-microphone noise/echo-cancelation technology that eliminates unwanted background noise. The Digital Signal Processing (DSP) technology digitally compares the signals from the two microphones and subtracts the common background noise resulting in clearer communications. The multipoint technology allows direct connectivity between the headset and two mobile phones.
