The Samsung WEP870 can be used as both a mono and a stereo headset. It has a dedicated on/off switch, a handy OLED display, comfortable earbuds, and good sound quality.The Samsung WEP870 looks like a normal Bluetooth headset from the outset. The WEP870 is rectangular with curved corners, with silver chrome trim and a mostly black surface, and it measures 1.77 inches long by 0.7 inch wide by 0.47 inch thick. Though it isn't too obvious, the upper part of the front surface can be pressed down to act as the multifunction call button. We found it easy to press, even when worn on the ear. Underneath that is a tiny OLED display that shows the battery life, Bluetooth connection status, and phone call connection status.
