The Sennheiser HD800S has great build but comes up way short in tonality. It is light in bass which is typical of many headphones but also cheats us the energy between 1 and 4 kHz. I paid for all the tonality in my music and I want all of it reproduced darn it! Fortunately equalization works despite the massive amount of amplification required in low frequencies. Once there, this headphone is doing something I don't hear with any speaker system and not yet on any headphone. It manages to provide a spooky layering and I guess I should say clarity that is not only surprisingly but delightful. I don't know if the effect will be too much if it comes across a lot of music but so far, I can't help but liking it and liking it a lot.
On a comfort side the HD800S is a delight. I find a lot of other headphone confining but not the 800S. Combine this with the post Equalization and you have a headphone I don't want to part with!
If you don't use equalization then this is not a headphone for you. But if you do use it (as you must with any headphone), and can afford it, the HD800S is a delightful way to experience music. I am going to put The HD 800 S on my recommended list.

Objectively we have the "old school" frequency response tuning with deficient sub-bass response and some in the upper mid-range, lower treble. What is missing is not significant enough to leave you disappointed if you paid $400. But at $4,000, you better find a way to add EQ and get the sound to the next higher level.
I struggled with what grade to give the Utopia. It straddles the fence between recommended and "happily recommended" with the latter being with EQ. At the end, I went with the latter.
