You may have read glowing reviews around the web about these cans. They aren't exaggerating. The AH-MM400s are thrilling on every level. The sound quality is amazing, with treble, bass, and mids finely balanced, allowing each note in each song to shine regardless of genre. I listen to a variety of music, from metal to electronic, jazz, rock, rap, and live tracks. Take note, there is a "break-in" period for these headphones, with full potential reached after about 80 or so hours of use. The wait is well worth it.
I wasn't surprised to find great audio quality with these headphones (after all, its what's kept me hooked on Denon for the past five years. I've tried other brands and they never are able to match up.). The real value is in the feel and construction. The MM400s are undeniably the most premium headphones I've owned--aesthetically pleasing to look at, and a joy to wear. There's little, if any, plastic in the construction, and while this may make the headphones feel a little bit heavier when you hold them, you won't notice it at all when they're over your ears. I've read a lot of purists lament at the use of synthetic leather in the padding, but if comfort is what you're going for, you're still getting your money's worth. And don't let the pictures fool you: the wood on the cups looks even better in person.
Another problem I ran into with previous Denon products (particularly the D1100s) is the tendency for cable wear. This problem is virtually eliminated with the MM400s. The cable can be unplugged, and even comes with a secondary (granted, one has a control for iPhone usage), and in some reviews I've read, third-party cables work just fine if you require a longer cable.
Needless to say, I'm a huge fan of the MM400s. If you're the kind of audiophile who looks for top-notch sound, build, and feel, and spend long hours wearing your headphones, you can't go wrong with these.
I would stay away.
Issues:
1. The sound has a weird synthetic attenuation to them that is quite distracting and un-natural sounding. In fact all of the music I listened to sounded synthetic with these.
2. Physically TOO SMALL - I don't have a large head and these were squeezing my head together in an uncomfortable way.
3. The balance is off - the left ear is louder than the right ear. This may be due to the fact that there is one wire going into the left ear then going into the right ear rather than independent wires for each ear.
Positives:
1. I like the walnut exterior and the overall build quality is solid.
I'm going to try the Creative Aurvana Live headphones instead as they are supposedly the same headphones as the made by Fostex which made the AH-D1001.
