The exclusive ear cups made from high-quality American walnut wood ensure a particularly natural and distortion-free reproduction of music at the highest level. The over-ear construction also provides a high degree of passive acoustic isolation.
Aluminum Headband
The ear cups are connected by an adjustable-length headband made from an aluminum alloy, featuring a lightweight and comfortably padded headband with special memory foam. Additionally, the AH-MM400 can be folded compactly for transport in the included carrying bag.
40 mm Carbon Fiber/Paper Diaphragm with FreeEdge Neodymium Magnets
The AH-MM400 is equipped with 40 mm drivers featuring an advanced carbon fiber/paper composite Free-Edge diaphragm and neodymium magnets. This Denon-exclusive construction ensures low distortion and a frequency range up to 40 kHz.
Modern European Design
The design of the AH-MM400 was conceived in Europe, combining classic style with a modern touch.
High-Quality OFC Cables
The AH-MM400 comes with two interchangeable audio cables, one of which is equipped with a remote control and microphone. This allows users to utilize this cable for their smartphone, while the other remains at home connected to the stereo system, made from OFC material (extremely low-oxygen copper).
