Included with the headphones are 3 pairs of inserts/filters of different thicknesses and materials that can be used to additionally tune the headphones somewhat to personal taste. The manufacturer states that the headphones are tuned to closely follow the HARMAN headphone preference target which was developed based on research conducted by Dr. Inside each earcup is a proprietary 62mm x 34mm single-ended planar magnetic driver, designed and developed in-house. Unlike the Aeon 2 Open that Mel reviewed, the Aeon 2 Noire is only available as a closed-back design. Very slick looking! The earpads are suitably soft and thick and are covered in a soft Japanese synthetic protein leather with perforations on the front half of the interior walls. I like that they are finished in a deep, polished black color with the carbon fiber weave pattern visible on the outside of each cup. The earcups themselves are made of aluminum with a carbon fiber baffle. The arms attach via a single point to the oblong-shaped earcups. I like the design of them because they remind me of the suspension arms from a high-performance car. These delicate-looking machined aluminum arms are what allows the Aeon 2 Noire to collapse into such a compact package for travel. At each end of the Nitinol headband are a pair of aluminum arms that are connected by a pivot hinge. Attached to that base frame is an adjustable wide leather band that suspends the headphones on your head. The minimalist wire-style headband is made from lengths of Nickel-Titanium (Nitinol) for increased durability. These headphones collapse for travel in the same ingenious way as Mel found and they take up minimal space when in their hard-shell case and tossed in a backpack. On the surface, the Dan Clark Audio Aeon 2 Noire looks very similar, in many respects, to the Aeon 2 Open headphones that Mel Martin reviewed last year. There are currently 3 models in Dan Clark Audio’s Aeon headphone line, the Aeon RT, the Aeon 2, and the Aeon 2 Noire.
While I have sampled (and own) loudspeakers that are designed to follow that speaker preference model, I don’t know that I’ve listened to a pair of headphones that have purposely claimed to do the same. Third, and probably most intriguing is that the Aeon 2 Noire is purposely tuned to track the HARMAN preference curve for headphone frequency response. Second, they are a very fetching black color and that’s the only shade they come in.
What makes the Noire different from the pair of headphones that Mel reviewed? Well, first they are only available as a closed-back design. Finally, through a combination of good timing and admittedly some minor league jealousy at Mel Martin’s excellent review of the Dan Clark Audio Aeon 2 Open headphones, the company graciously sent me a pair of the new AEON 2 Noire to try out. But the Aeon line also caught my attention for both its supreme comfort and impressive sound quality for the price. DCA’s higher-end Voce (electrostatic) and Ether (Planar) headphones have always been must-listen-to items whenever I was at a show, as I found them to be good touchstones to compare against other similar products. Each year, whether at RMAF or CanJam, or even Munich High End, the designs would increase in both quality and sophistication, and the resulting sound would follow suit. I’ve always admired their plucky spunk as an upstart headphone modding company and watching them progress into designing and building their own headphones from the ground up. I have had a chance to sample their headphone wares at various audio shows over the years, but I had not gotten around to conducting a review before. But intense twig cutting was also found on critically endangered plants, so twig cutting by black rats could be a threat to those species.I’ve been a closeted fan of Dan Clark Audio (formerly MrSpeakers) headphones for quite some time. Because the overall proportion of individuals damaged by twig cutting was not high, the behavior is unlikely to influence the population dynamics of trees and cause vegetation change. This may be due to an evolutionary loss of plant defense mechanisms in the absence of herbivorous mammals. Endemic plants experienced a significantly higher probability of twig cutting than alien plants. This suggests that twig cutting is associated with particular characteristics of target species. Probability of damage by twig cutting was not correlated with species frequency in the vegetation. Twig cutting was greatest in spring (March-May).
Overall, 42.6% (23/54 species) of woody species were damaged. Censuses were conducted along seven routes to count the number of trees damaged by twig cutting in each month. We examined seasonal patterns of twig cutting by the introduced black rat, Rattus rattus, on Haha-jima Island, an island in the Ogasawara (Bonin) group of Japan.
