The Plantronics M1100 and the D975, which are quite famous in Plantronics, are also designed by BMW designers, although their appearance has changed a lot. The Plantronics M1100 can connect two devices at the same time, with three microphones designed for noise reduction, WindSmart wind noise prevention technology and A2DP support. Although it is not as cool as the 975, it is still a Bluetooth headset worth choosing.

The latest version of Plantronics M1100 has a low price of 21.99 dollars, about 133 yuan, and a price of 200 yuan. The brand new price is about 40 dollars, and the same price in China is 500 yuan.
