The Master & Dynamic MH40 headphones come complete with detachable cables, a leather cable box and a carry pouch. You can take them on the road or listen at home wirelessly through a Bluetooth 5.0 connection. The 1.25m cable has a mic, so you’ll be able to adjust the volume on your iOS device, as well as handle calls and manage your tracks.
Stunning design features and comfortable wear
The headband has been produced in robust aluminum and finished with soft cowhide, so it feels lightweight and stays comfortable. The cups have memory foam padding, and a cover made from velvety lambskin ensures they feel soft against your ears.
Eighteen hours of portable sounds
Master & Dynamic MH40 headphones will be fully charged in an hour and you can expect around eighteen hours of play. If you don’t have that long to wait, just leave them plugged in for 30 minutes and you’ll still have an acceptable nine hours of tunes.
Warm audio and no distractions
As you’d expect from premium headphones, the audio quality is good, with sparkling vocals and natural-sounding instruments. A pair of 40mm drivers create a loud, expansive level of sound whilst keeping the base clean. For uninterrupted listening, Master & Dynamic have added a beamforming noise reduction feature that simultaneously amplifies your tracks and minimizes exterior sounds.
Is there a Master & Dynamic app?
No, you can’t customize your listening experience using an app.
