These blue Master & Dynamic MH40 wireless headphones are crafted from lightweight anodized aluminum, coated canvas and leather for a vintage aviator-inspired design. With Neodymium Drivers sound technology, they offer rich sound, quick pairing Bluetooth connectivity, a mic filter and up to 18 hours of playtime. They come with USB-C to USB-A and audio cables, as well as a carrying pouch. What’s that sound, you say? Oh, it’s just the whoops of delight we’re making as we open the brownsfashion.com parcel containing our new Master & Dynamic headphones.
