Our take on the Denon AH-MM400
The Denon AH-MM400 headphones walk the walk and talk the talk. These headphones have a classic European design with a modern touch and offer a superb musical experience. The ear cups are collapsible so you can easily carry the headphones with you. A high degree of passive acoustic isolation gets rid of any annoying background noise. These headphones come with two cables, one cable has a microphone allowing you to talk on the phone and the other cable is for connecting to other devices.

Designed to look as good as they sound, the AH-MM400 feature a fresh European style-inspired design that combines classic styling with a modern touch.
Aluminum Die-Cast Hangers
The ear cup housings connect to the lightweight adjustable headband via aluminum alloy die-cast hangers, which feature resonance-free construction, along with high rigidity for maximum durability. The AH-MM400 also feature collapsible ear cups for storage in the supplied carrying pouch.
Natural American Walnut Ear Cups
Featuring hand-carved natural American Walnut ear cup housings, the AH-MM400 deliver a superb musical experience, with balanced tonal quality thanks to the resonance-free natural wood housings. Sporting 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 background noise interference.
40mm Carbon/Paper Composite Diaphragms with Free Edge and Neodymium Magnets

Oxygen Free Copper Cables
For the utmost audio fidelity, the AH-MM400 come 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. The other longer cable is provided for connection to other devices, and both cables feature gold-plated connectors.
