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 Plantronics M1100 recently has a low price of 29.99 US dollars, about 185 yuan, and the price is about 220 yuan. At the rate of 500 yuan for the same model in China, the price advantage is obvious.
