Denon AH-MM400 Audiophile Quality Over-Ear Headphones

Discover a whole new world of musical enjoyment with Denon's AH-MM400 reference class 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 features a fresh European style-inspired design that combines classic styling with a modern touch.

Aluminum Die-Cast Hangers

The earcup housings connect to the lightweight adjustable headband via aluminum alloy die-cast hangers that feature resonance-free construction, along with high rigidity for maximum durability. The AH-MM400 also features collapsible earcups for storage in the supplied carrying pouch.

Natural American Walnut Earcups

Featuring hand-carved natural American Walnut earcup housings, 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 background noise interference.

40mm Carbon/Paper Composite / Oxygen Free Copper Cables

The AH-MM400 features 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 40 kHz.

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. 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 there's also an adjustable Bass Boost mode.

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. The Tunein service features selections of internet stations by global region, music genres and features locally recommended stations as well.

Headband broke while wearing after less than 7 months - Denon Support worthless

Headband broke while wearing after less than 7 months - Denon Support worthless
I absolutely LOVED these right up until the headband broke literally as I was wearing them. I called Denon Support and they told me they couldn't replace them because the headband counted as &#34;cosmetic damage.&#34; How can something necessary to the functioning of the headphones be cosmetic? Without a functioning headband, these are completely unusable. I can't wear them.I've owned 3 other Denon headphones, a receiver, turntable and hifi CD player, but I'll be taking my brand loyalty somewhere that stands behind their products.
