Master & Dynamic 2014年诞生于纽约，在欧美有较高的人气，Apple Store和不少影音专卖店里都能看到它的身影，足球明星贝克汉姆就是Master & Dynamic的用户。Master & Dynamic注重设计，产品外观时尚复古，品牌定位与B&O类似，整体价格偏高。
 
Master & Dynamic的earphone并非花瓶，其MW60被Engadget评为最佳无线earphone，MW50+被Wired认为是最佳头戴贴耳式earphone，MW50则是VGP 2018 SUMMER的获奖型号，同时这三款earphone也是Master & Dynamic仅有的三款Bluetooth headset。
 
The MW60 priced at 3799 yuan has the highest positioning, adopts an ear-covered design, the surface of the detachable ear cushions is lambskin, supports aptX Bluetooth coding, and the diameter of the driver unit 45mm is also larger. However, its battery life is only 16 hours below the industry average, and the weight of 345g is slightly heavy on the head. In terms of hearing, the MW60 is rich in detail, with a strong sense of stereo and a strong sense of low frequency.
 
The MW50 at 2599 yuan and the MW50 at 3499 yuan are actually the same headphones, but the latter comes with a larger pair of ear pads, which allows the earphones to switch between on-ear and over-ear forms. The MW50 is 30% smaller than the MW60, uses the same lambskin ear cushion surface, supports aptX Bluetooth encoding, and has a more convenient Type-C charging interface. However, the battery life of MW50 is also only 16 hours, and the ear clamping feeling is obvious after wearing it for about 2 hours, and it is not foldable, so it is not easy to store. The MW50 is driven by a 40mm berylliumium driver, which is stiffer than other metals for clearer sound. In terms of actual hearing, the middle frequency is relatively prominent, but the low frequency lacks texture, and the three frequencies are still balanced as a whole.
