■　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.

■　Background
Sound is conveyed to people's ears as waves that occur when vibrations from a sounding body causes 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 those, you need headphones that let you freely enjoy the music and 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,
• 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. We invite you now to produce your own space where you can enjoy them to your heart's content.

■　Main Features of AH-D5000
● Wooden housing
Employs housing made of natural wood with superior acoustic characteristics that are rich with a broad, natural sound.
● Microfiber diaphragm
Microfiber has been used to form the diaphragm so that it faithfully reproduces the　sonic details and delicate reverberations that occur in concert halls.
● Acoustic optimizer
Optimum acoustics characteristics are achieved by　adjusting the sound pressure balance in front of and　behind the diaphragm.
● L/R equal cable co＼nnection
High-quality cables of equal length for the L/R channels are used to maintain　optimum　sound quality. High-purity 7N-OFC cables with a cloth mesh jacket are used.
● Light-weight magnesium frame
This frame lets listeners enjoy maximum comfort during extended listening sessions.
