Denon AHMM400 Reference-Quality Over-Ear Headphone
Denon AHMM400 Reference-Quality Over-Ear Headphones are designed for the serious listener and are part of the company’s “Music Maniac” line of headphones. They are professionally tuned for the flattest response over the widest frequency range among the series. The over-ear design provides passive acoustic isolation without the need for active noise cancelation. They feature a contemporary European design that fuses classic styling with a modern touch. The hand-carved American Walnut earcup housings provide a natural tone and elegant looks.
The proprietary 40mm drivers feature the company’s “Free Edge” technology along with carbon/paper composite blend diaphragms and neodymium magnets, as well as ceramic-like finished ellipsoid earcups with reinforced glass fiber to curb resonances while reducing weight and retaining rigidity. The earcup housings connect to the adjustable headband via aluminum alloy die-cast hangers with a resonance-free construction and high rigidity for maximum durability. This combination delivers a wide extended frequency response of 10 to 40,000 Hz into a 32 ohm impedance with a sensitivity of 96 dB/mW.
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
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.
