I picked these up on a discount, got them for 140 dollars. I didn't expect much to be honest, got them just because they were at less than half their usual price. They sound pretty good out of the box. I expected a bass heavy sound V-shaped sound, especially with the music maniac written on the box, but it's exactly the opposite. Its quite neutral sounding, especially the bass. Not that there's no bass, there is, and its well extended and smooth, but its quite neutral, very tight and punchy, not at all loose. Overall balance is somewhat bright. There definitely is some high frequency emphasis which makes it sound particularly clear and fast. It sort of reminds me of the T1 in a way when it comes to overall balance. Smooth and neutral with a slightly spiky high end. Vocals and high pitched instruments are quite forward sounding. Soundstage is not very big, but it is expansive and deeper than expected for a closed portable headphone. The best thing is, it sounds great out of an iPhone, so I'm glad it will work as a portable headphone in that respect.
What I don't like is the fact that I got only one short cable, no longer cable for home use, so I'll have to spend more money on that. Also, they fit weird, there's barely any clamping force, and them being on-ear headphones, they feel really loose on the head, because they're basically sitting on ears without pressing the ears onto my head, so it only takes a force that usually bends the ears to move the headphones, add to that a very small contact area on the headband, and it all results in a very sloppy fit. I can't move my head without feeling like they will fall off. They're also quite big and bulky. They stick out to the sides of my head when wearing them.
Lastly...Denon, a tip for you. If you're gonna make a downloadable app on the Appstore, and make it free to download, then make the freaking features of the app free. This is the first music playing app that requires me to pay $1.99 to use a freaking equalizer. I payed for the headphones, I want the app for free as it says on the box. Its not about the 2 dollars, its about the principle.
