It is still the product of Sennheiser, an old headset manufacturer. The MM500-X is the Bluetooth headset of the previous year. It supports A2DP and can be used on PCs and mobile phones, and has corresponding keys for control. It has its own noise reduction technology and SRS sound effect.
Sennheiser MM500-X is currently at a low price of 261.51 dollars, about 1600 yuan. After checking, it seems that there is no corresponding line of goods in China, and Taobao has sold it for about 2000 yuan.
