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.

Product Information

Classic Style with a Modern Touch

Discover a whole new world of musical enjoyment with Denon's AH-MM400 Music Maniac Audiophile On-Ear Headphones, which are professionally tuned for a flat EQ and deliver a natural tonal balance that's faithful to the original musical performance. 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

The AH-MM400 feature proprietary 40mm drivers with advanced Carbon/Paper composite blend diaphragms and neodymium magnets along with Denon's exclusive Free Edge technology, which dispenses with the traditional diaphragm surround suspension to deliver extended frequency response all the way up to 40kHz.

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.

Denon Audio App

Download the free Denon Audio App (available in iOS and Android versions) to your smart device and enjoy the ability to custom tailor the sound via the 5-band equalizer. Choose the Flat mode for linear tonal balance, or select any of the 9 available custom EQ curves. Or choose the Manual mode and adjust the tonal balance to your liking.

There are also 3 adjustable DSP modes: the Virtualizer lets you widen the acoustic soundstage, while the Reverb mode lets you add additional reverberation to dry recordings, and then there's also an adjustable Bass Boost mode.

In addition to all this, the Denon Audio App includes TuneIn internet radio, a free streaming music and audio service that lets you choose from thousands of Internet radio stations around the globe.

how is the sound quality?
A shopper on Oct 2, 2017
  In short: awesome! The frequency response of 10Hz-40,000Hz really makes a difference when it comes to clean detail. Overall, these cans are on the smoother, warmer end of the spectrum, but still offer plenty of finesse for Hi-res listening. The bass is strong, accurate, and clean, but doesnt interfere with the mids. The closed-back design and high-density foam ear cups will keep away most noise in your environment.
