Denon AH-MM400

Targeted to serious music listeners, Denon’s new Music ManiacTM headphones are packed with advanced technologies, and feature pro- prietary drivers and housings. Discover a whole new world of musical enjoyment with Denon’s AH-MM400 reference class headphones, which are professionally tuned for the flattest response over the widest frequency range among Music Maniac series.  It features an over-ear (circum-aural) design that provides top comfort as well as passive acoustic isolation without the need for noise cancelling, and features real American Walnut earcup housings that provide natural tone and elegant good looks.


Natural American Walnut Earcups

Featuring hand-carved natural American Walnut earcup hous- ings, the AH-MM400 delivers a superb musical experience, with balanced tonal quality thanks to the resonance-free natural wood housings. A comfortable over-ear (circumaural) design, the AH-MM400 provides a high degree of passive acoustic isolation, letting you listen to your favorite tracks without distracting back- ground noise interference.


Aluminum Die-cast Hangers

The earcup housings connect to the lightweight adjustable headband via aluminum alloy die-cast hangers that feature res- onance-free construction, along with high rigidity for maximum durability. The AH-MM400 also features collapsible earcups for storage in the supplied carrying pouch. 40mm Carbon/Paper Composite Diaphragms with Free Edge and Neodymium Magnets The AH-MM400 features proprietary 40mm drivers with ad- vanced Carbon/Paper composite blend diaphragms and neo- dymium magnets along with Denon’s exclusive Free Edge tech- nology, which dispenses with the traditional diaphragm surround suspension to deliver extended frequency response all the way up to 40 kHz.


Oxygen Free Copper Cables

For the utmost audio fidelity, the AH-MM400 comes with 2 detachable audio cables, both featuring high purity Oxygen Free Copper (OFC) cable technology. One cable features a built- in microphone along with a remote control for volume, track selection and smartphone control (compatible for iOS devices). The other cable is provided for users who prefer without remote control, and both cables feature gold-plated connectors.

Contemporary European Design
