Denon's Development Concept
The AH-D5000 and AH-D2000 have been designed for music lovers who want to enjoy a realistic sound in complete peace, while the AH-D1000 provides a high quality sound that can be easily enjoyed outdoors as well as indoors.
Precision Denon Engineering
Sound is conveyed to people's ears as waves that occur when vibrations from a sounding body cause the air to vibrate. In a normal listening environment, sound waves released from speakers fill the listening space, and the waves that reach people's ears are reflected or absorbed by objects in the room such as desks, chairs, sofas, the floor, ceiling, or carpet. This is how we, through audio products, enjoy music recorded in a concert hall, live house, or studio. If you wish to enjoy an ambiance as though you were sitting in a concert hall or live house, you would have to raise the volume on the amp to some extent and drive the speakers. However, if your free time to enjoy music occurs late at night, you may not be able to raise the volume. At times like these, you need headphones that let you freely enjoy the music and yet still give you the quality of sound you require. To develop such headphones, we at Denon embarked on a new path where we focused on the acoustic space inside the headphones rather than the listening room.
Wearing headphones is like placing your ears right beside the speakers. The sounding body vibrates the air, but instead of being influenced by surrounding objects, the sound waves go directly into your ears. At first glance, you might imagine hearing a beautifully realistic sound, but there are a few issues that must be addressed first: The driver unit needs to reproduce both delicate details and powerful sound, The materials used for the housing need to have superior acoustic properties, The headband and frame need to feel natural while being worn, and The cable needs to preserve the purity of electric signals during transmission. Denon engineers have cleared these challenges step by step through repeated listening tests and adjustments. Musical instruments produce a wide variety of delicate nuances in sound that are most enjoyable to listen to--and now you can produce your own space where you can enjoy them to your heart's content.

My perspective is a bit different:
Let me preface this review with a few points that should add to the review's credibility:
1. I am a classical sound engineer primarily, but work exclusively in acoustic genres where audio fidelity and sonic accuracy are paramount.
2. I work in both balance engineering and mastering, where I am often required to perfect the spectral balance (in both dynamic and frequency) of the final mixdown.
3. For over 10 years I have used Bowers and Wilkins loudspeakers in various environments (anechoic and otherwise) in addition to custom EQ'd headphones for my work. B&W is widely believed to manufacture the finest loudspeakers in the world.
4. I regularly attend live classical music concerts, often in ideal seating locations, resulting in a great familiarity of how live music sounds.
I researched a number of headphone options before settling on the Denon AH-D5000. I was curious about the Ultrasone models from Germany, but was wary of a technology that supposedly "corrected" cross feed and phase issues often experienced with headphones. The Denon frequency response curve was generally smooth, and any corrections could be made with a high quality EQ within the DAW.
There are immediately two things that are apparent when you first hear the AH-D5000. They require extensive burn-in. I have been listening to these headphones for approximately 5 days now, attempting to leave as much signal in them overnight as possible. There has been a very apparent change in their sonic character as related to frequency response throughout this period. I can tell you that burn-in is a very real requirement for those of us in the music recording business. Loudspeakers often are very rigid when new, resulting in a limited frequency response and higher than normal distortion-giving you that characteristic "hard", new sound. Headphones present the same challenge, and these Denons require significant burn-in. What appears to be happening over time is a reduction of deviation from a flat frequency response, resulting in a smoother curve as time goes on. I would not be surprised ...
