Denon AH-D9200 headphone review: Superb sound quality in a luxurious, closed-back, over-ear headphone


Headphones offer several advantages over speaker systems. Perhaps most importantly, they remove the acoustic effects of the room, providing a more consistent and predictable listening experience. As a result, headphones continue to inspire a thriving hobbyist community.

Denon has been making highly regarded headphones for more than 50 years, and the AH-D9200 is the company’s latest flagship model. I reviewed it using Denon’s PMA-60 two-channel integrated amplifier, a combo that makes beautiful music together.

Features

The AH-D9200 is a circumaural (over-ear), closed-back design handcrafted with premium materials. For example, the outer casing of each earcup is made from bamboo, which is said to have natural acoustic properties that greatly reduce unwanted resonances and promote a rich, warm tone. In addition, the memory-foam earpads are clad in engineered leather for maximum comfort over long listening sessions.

The hanger hardware is very sturdy, allowing comfortable seating on a wide variety of head shapes and sizes.

A diecast-aluminum hanger provides sturdy support and flexibility, allowing the earcups to move freely around two axes for maximum comfort on a wide variety of head sizes and shapes. Comfort is also enhanced by the headband, which is wrapped in genuine leather. But despite the use of such high-end materials, the AH-D9200 weighs only 375 grams (13.23 ounces).

Each earcup houses a 50mm free-edge diaphragm made from nanofiber materials chosen for rigidity and low mass. The diaphragm is mounted in a vibration-reducing engineered-resin baffle with a soft surround material that makes it easier to move in response to the music signal without flexing or distorting. This design is said to cancel out resonances in the diaphragm.

With a specified impedance of 24 ohms and a sensitivity of 105dB/mW, the frequency response extends from 5Hz to 56kHz with a maximum power handling of 1800mW. The neodymium magnet boasts a huge magnetic field strength of more than 1 tesla, which is said to drive the diaphragm with lower distortion and reduced vibration. To put this in perspective, most medical MRI machines have a magnetic field strength of 1.5 teslas, while Earth’s magnetic field is in the range of 25 to 65 microteslas at the surface.

Without the earpad, you can see how the driver is mounted in the earcup.

The AH-D9200 comes with two detachable OFC (oxygen-free copper) cables, both of which connect to the two earcups with 3.5mm plugs. The copper wires in the 3-meter cable are silver-coated for higher conductivity, and the cable terminates with a 6.3mm (1/4-inch) plug for a home stereo system. The wires in the 1.3m cable are not silver-coated, and it terminates with a 3.5mm plug for portable devices. The shorter cable also includes a 1/4-inch adapter.

The included storage case and cleaning cloth help keep the headphones safe and pristine. Unfortunately, it’s somewhat flimsy cardboard. I would expect a more substantial case at this price.
