Acoustically Pure On-Ear Headphones

So Acoustically Pure,

it’s like hearing your favoritesong for the first time.

When was the last time you really sat and listened to your favorite piece of music? With Denon’s line of Music Maniac headphones you’ll want to do it again, and again, and again.

Some people are just as obsessed about sound quality as we are. And they know sound quality is much more than the size of the driver and the cavity space in the ear cup – it’s further enhanced by the right cables, the right connectors, the right tuning. At Denon we’ve sweated the details so you don’t have to. Just put a pair of Music Maniac headphones on, plug them into your Denon amplifier or A/V Receiver sit back and hear your music like never before. However, for those people who live busy, hectic lives we should offer a warning. You may become so immersed that you could lose track of time.


40mm Drivers

Professionally tuned to a flat EQ.

Denon’s Music Maniac AH-D340 On-Ear headphones feature 40mm full range drivers with a passive crossover and are professionally tuned to a flat EQ so you can hear your music just as the recording artist intended you to hear it.

Detachable cable

with in-line remote & microphone gives you control & communication:

The Denon Music Maniac On-Ear headphones feature an in-line remote & microphone for easy control of your Apple® iPod®, iPhone® or iPad™ and it’s placed slightly higher on the cable towards your mouth than conventional models for enhanced call clarity.


Feel the Music.

Not Your Headphones:

Real music aficionados get so immersed in their music that it’s easy to spend hours enjoying their favorite tunes in pristine quality. At Denon we believe you should feel the music, not your headphones. In a quest to provide the most comfortable, best fitting headphones, Denon’s engineers have studied over 4,000 pairs of ears from people around the world, to come up with a design that automatically accounts for the subtle differences in ear shape, placement, ear canal size, head size and jaw depression. We know that fit and comfort comes from paying attention to the small details. Think about it – your ears aren’t round, so why settle for round ear pads? Denon’s Music Maniac On-Ear headphones feature Denon’s patent-pending pentagonally-shaped memory foam ear pads for maximum comfort and fit from an on-ear form factor, while the 2-axis ear cup construction allows the ear pads to articulate 360-degrees to provide the perfect fit. Add to that our adjustable headband which allows for a total expansion of 6-inches to fit larger heads.

Hearing is Believing.

While other headphone manufacturers may try to sway you with marketing phrases like “music the way that the artist intended it to be heard”, we know that hearing is believing. We invite you to visit your nearest audio retailer and audition these headphones.

Denon’s Audio App,

for iPhone, iPad or Android, enhances your experience.

While many audiophiles shun listening to music on their smartphone, we realize that eventually resistance may be futile. That’s why we created the Denon Audio smartphone application. This application allows you to customize your listening experience by creating, storing, and sharing custom EQ curves and features a real-time spectrum analyzer; create and store custom playlists; enjoy over 70,000 internet radio stations worldwide via TuneIn Internet Radio service; and automatically update your Facebook/twitter status (if you’re into that sort of thing). Pair the Denon Audio app with Denon Music Maniac Headphones and get a truly enhanced audio experience from your smartphone.
