Sanwa Supply Bluetooth Headset External Black Free (with Microphone) MM-BTMH61BK

Comes with a unidirectional external microphone. The headset itself also has a microphone, so you can use the headset's microphone when you go out, or use an external microphone when indoors, depending on the purpose. The external microphone can be moved and adjusted to the desired position. The microphone is placed near your mouth, so you can talk with confidence. The soft ear hooks won't hurt your ears.
