The latest addition to Denon's headphone range is the £250 AH-D2000, described as 'Reference-Class Closed-Back Hi-fi Monitor Headphones'.
They've been designed and voiced by the same high-end hi-fi engineering team responsible for the company's Advanced Evolution audio components, and use lightweight magnesium for the headband and the frames of the earpieces.
The AH-D2000s have been designed to keep the music in and noise out, making them perfect for enthusiasts who have to listen while others are watching TV or whatever. That's why they've been designed to be light, and have soft earpiece padding to maintain comfort over long listening sessions.
A ball-bearing 'click' adjustment makes it possible to get – and maintain – an accurate fit.
The main capsule housings are made from a damped composite material, and the transducers use a high-density microfiber diaphragm designed to be rigid, light and ultra-fast.
50mm neodymium magnets are used, along with Denon's proprietary Acoustic Optimizer, which is designed to adjust the pressure in front of and behind the diaphragm. This is said to allow greater movement and speed, and thus a more open and airy sound.
The AH-D2000s have high 108dB/W/m sensitivity and 25 ohm impedance, and claim a frequency range of 3Hz-45kHz. They weigh 350g, not including the 3m cloth-covered oxygen-free copper cable, and come with a 3.5mm plug as standard. A 6.3mm adaptor is also supplied.
