The Absolute Sound as compared to just sound? re: Headphones.

Because of most listening being late at night/going to sleep with the Nak SoundSpace 5, I would think under 200.00 and as of now I do not stream.  Thanks for you input.  Jim

soix, as a P.S., I have three places I might listen to "phones" with.  A main system with CJ-ART, Magnepan...etc, a 2nd system with a Magnum Dynalab receiver, Quad 12 speakers and Wireworld interconnects and a "for late night/going to sleep" Nakimichi Soundspace 5....which would be the most likely place to use headphones.  With all my systems now and throughout my life, sound quality is my goal, volume has never been anything of interest. 
Perhaps not on this site, but many Americans have a jukebox at a bar as their sound quality standard/comparison.  

soix, Thanks for you thoughtful post.  My listening is mainly classic Jazz from the 40s through the 70s and  well recorded female vocals doing standards and Jazz vocals.  I prefer acoustic instruments with an allowance for well recorded electric guitar and bass.  Being esoteric should never be taken as arrogant.  Knowledge and/or experience that is shared is a gift that the reader/listener can accept, reject or modify based on personal experience.  It is done with film and restaurant reviews world wide, and should be no different with most consumer goods.   Having driven race cars at Road America, I understand that is a non-standard experience and perspective on handling and how to drive.....For many "going out to eat" means a place with a drive-up window, but that is not what I consider a dining experience. .......however, there are always Twinkies and Ding-Dongs....for real gourmet foods. 

Thanks, the  HIFIMAN seem to be a choice many agree with.  I will give them a listen.
