Наушники — Denon AH-D9200

The AH-D9200 is a sealed over-ear model that Denon describes as its flagship and builds entirely in Japan at the Shirakawa Audio Works facility. It carries Hi-Res Audio certification and a current Denon list price of USD 1,799, and the brand places it in a headphone history that it counts at more than 50 years.

Key specs that matter

A 50 mm FreeEdge driver with a nanofiber diaphragm is fitted on each side, powered by a neodymium magnet rated at over 1 T. Denon gives an impedance of 24 ohm, 105 dB per mW sensitivity and a 1,800 mW power handling limit, with a frequency range stated as 5 Hz to 56,000 Hz. Weight is 375 g. Two detachable cables are included - a 3.0 m lead of silver-coated oxygen-free copper with a silver-plated 6.3 mm plug, and a 1.3 m lead ending in a 3.5 mm plug. Both split into a pair of 3.5 mm plugs at the headphone end, and a 3.5 mm to 6.3 mm adapter, a storage box and a cleaning cloth complete the package.

Engineering and use context

The diaphragm material was picked for high rigidity and low mass, and the soft, compliant surround of the FreeEdge layout lets it move without flexing at the edges, which Denon links to lower resonance and distortion. The drivers sit on baffles of engineered resin intended to reduce vibration. The magnet is an alloy of neodymium, iron and boron, whose strength lets a compact magnet drive the diaphragm with less vibration while taking up little space in the cup. The housings are made from Japanese bamboo, chosen for its damping of unwanted resonance, and because the grain differs from piece to piece every pair has its own pattern. A diecast aluminium hanger frames each cup, the headband is leather, and the earpads combine soft engineered Japanese leather with 3D-shaped memory foam. Denon designed the clamping force to be low so that long listening sessions stay comfortable, and the leads are tested at the Shirakawa plant.

Pairing

The AH-D9200 is an easy load for almost any source, so the shorter lead can go straight into a portable player or phone adapter while the long cable serves a home headphone amplifier or the front jack of an integrated amplifier. The high power handling limit means a powerful desktop amplifier will not stress the drivers. Because the cups are sealed, the model also works in shared spaces where open-back designs leak too much.

Alternatives

The Denon AH-D7200 is the closed-back model one step lower, with American walnut cups, a 25 ohm rating and a 385 g weight.
