Наушники — Denon AH-D7200

The AH-D7200 is a wired circumaural Denon headphone with sealed wooden cups, positioned directly below the AH-D9200 in the reference range of the Japanese brand. It went on sale in December 2016 at USD 999 as the successor of the AH-D7000, and Denon currently lists it at USD 1,099. The wood-cup model is certified for Hi-Res Audio and has no Bluetooth, no active noise cancelling and no folding hinges.

Key specs that matter

Inside every cup sits a 50 mm dynamic driver with a nanofiber diaphragm on a FreeEdge suspension, and the drivers are made in Japan. Rated impedance is 25 ohm and sensitivity is 105 dB per mW, while the maximum input is 1,800 mW. Denon specifies a frequency range of 5 Hz to 55,000 Hz. The headphone weighs 385 g. A detachable cable of 3.0 m in 7N purity copper is supplied, terminated in a 6.3 mm plug at the source end and in two separate 3.5 mm plugs, one for each cup. A cleaning cloth for the wooden surfaces is packed with the headphone, and the only colour option Denon lists is the brown natural wood finish.

Engineering and use context

The FreeEdge name refers to the way the diaphragm is attached - a soft, compliant half-roll surround lets the stiff, low-mass nanofiber cone move as a piston with less flexing at its edge, which Denon links to lower distortion. The cups are cut from solid American walnut, so grain and colour vary slightly between units. The cups are held by curved diecast aluminium yokes, and the headband is covered in sheepskin leather. Memory foam fills the ear cushions, which are wrapped in artificial leather. Because the back of each driver is enclosed, very little leaks out to people nearby and outside noise is attenuated passively, which makes it usable in offices, on trains and in rooms where others are present. Splitting the cable into two plugs means each channel reaches its cup on its own conductor path, and the cable can be replaced if it is damaged.

Pairing

A 25 ohm load combined with 105 dB per mW means the AH-D7200 can be run straight from phones, pocket players and the jack on a stereo amplifier, and a separate headphone amp is not a requirement. The 1,800 mW input rating leaves wide headroom for desktop headphone amplifiers with high output power. The supplied cable ends in the large 6.3 mm jack, so a 3.5 mm adapter is needed for portable gear.

Alternatives

The Denon AH-D9200 is the next model up in this sealed-cup range and is made entirely in Japan, with Japanese bamboo cups, over 1 T neodymium magnets and a 5 Hz to 56,000 Hz rated range.
