Amplified Drivers: The AH-D400 Urban Raver over-ear headphones feature
50mm drivers powered by a built-in amplifier. This combination gives you
explosive bass response and enhanced treble. The headphone amplifier runs on a 3.7 volt Lithium-polymer rechargeable battery, which provides up to 12 hours
of use on a full charge. The amplifier can be switched on or off via a 2-way
switch, while a red LED on the left earcup indicates the level of battery
charge. You can turn on or off the blue LEDs on both earcups as you listen, if
desired. The headphones can still be used in the passive mode
after the battery power runs out. The battery charges via the supplied USB
Compatibility: The headphones feature integrated Apple-compatible
controls and microphone on the right earpiece. These can control music operation
on compatible Apple devices and conduct phone calls or perform voice recognition
activities. The AH-D400s are compatible with iPod nano (4th gen or later), iPod
classic (120GB/160GB), iPod touch (2nd gen or later), iPod shuffle (3rd gen and
later), iPhone (3GS, 4, and 4S), and iPad. Audio is supported by all iPod
models, as well as virtually any device with a 3.5mm minijack output.
On-ear Remote/Microphone: Denon's patent-pending Control
Wheel, located on the right ear piece, gives you control of your iPod, iPhone,
and iPad. The volume can be raised or lowered incrementally with a twist of the
wheel. While listening to music, you can control playback by pressing the center
of the wheel for play/pause, next track, previous track, fast forward, and fast
reverse. Phone controls include answer/end a call, switch to an incoming or
on-hold call, put a call on hold, or decline a call.
Headphone Cable: The headphones have a 55" Teflon-coated OFC
cable with a 3.5mm miniplug terminal. The clear, low-friction outer coating
helps keep the cable from getting tangled and reduces the chance you'll get
contact noise as you move. A 3.5mm-to-1/4" adapter is included for listening to
home components with a full-sized headphone output.
Comfortable Fit: The AH-D400 Music Maniac headphones are
designed for comfort and fit. Denon's patent-pending Pentagonally-shaped Memory

song lyrics, and create and store custom playlists. With the TuneIn Internet
Radio service, you can listen to any of over 50,000 internet radio stations.
