I bought these to replace my Superlux HD-330's that I had for almost 5 years before they broke down on me. At first I was a bit hesitant to buy these after a couple of reviews pointed out that the Black Edition has a different sound to the regular silver DT-880 Pro. I still decided to go ahead as the regular DT-880's were not in stock at the time when I was looking for new headphones. The fears of this being inferior to the regular DT-880's were quickly washed away.
The lows are definitely not dominant. I would describe the bass as tight and contained, so if you're looking for a loose low-end that dominantly fills the cup with every beat this headphone might not be for you. However, I find the lows to have almost perfect balance, leaving room for higher frequencies. The definition is good and won't be muffled by higher frequencies either.
The mids are quite bland. I can't say a lot about them, they just are. They definitely aren't bad, but not exceptionally great either. I could do with more clarity and crispness, however for this price I can't really complain. If something is a weakness in the sound stage, it is the mids.
I personally find these headphones to be more balanced towards the high end. Treble definition is very crisp and tends to push through the mids a bit, but I do not find this to be a major problem. This headphone definitely comes to life with higher frequencies. I would say this has the best high ends I've heard in any headphone I've tried out, but that just comes down to a matter of taste.
I would recommend to have an amplifier to accompany this pair of Beyerdynamics to get the most out of them.
Then to the comfort. I have a big head, but still I find these headphones to be very comfortable, even though the Pro version has a higher clamping force than the regular DT-880's. I can use these for hours straight even with glasses, so the clamping force is not a problem for me. A small downside is that I would wish the headphone could be adjusted just 0.5-1cm lower. The edge of the cushion barely rests on the lower part of my ear which does not bother me, but something I noticed did not happen with the previous pair of my headphones. It's not uncomfortable but a bit annoying, so I will have to deduct a star from comfort.
The looks. I've personally always liked how Beyerdynamics look. These are no exception, I prefer the black version over the regular silver one. It does not scream the brand name, so that's a big plus. Headphones are for listening, not for showing off.
All in all, this headphone is great for its price. I want to claim that you'll struggle to find as good a pair as this for this price. It's a great all-rounder: for music, for gaming, for entertainment...
I wholeheartedly recommend these headphones.
