Enjoy high sound quality with the Master & Dynamic MW60 Wireless. Thanks to the Bluetooth aptX profile, you can wirelessly stream music in high quality to the headphones. Because the headphones are wireless, you have plenty of freedom of movement while listening to music. The frequency range of 5 to 25,000Hz ensures that the bass in the music is extra powerfully reproduced. When you make hands-free phone calls, you can be heard clearly thanks to the noise-suppressing microphone.
