Sony - MDR-Z7M2

Given your request, it depends on your budget. For closed backs, Sony's have been the comfiest. The MDR-M1 is extremely light and sounds pretty good for their cost at around $200-$250. The MDR-Z7 and MDR-Z7.2 are more iffy on sound for me at their $400-$600 cost (without modification; excellent when modded) but contour and fit the head like no other headphone for me. They're each built like tanks too and my only complaints about their build/comfort is the use of pleather but they seem to use good quality stuff or have easy to find covers for the headbands or sheepskin replacements for the earpads.

Sony z7m2. Use them for my long coding sessions. Perfect comfort for my head

Personal favorite is the Z7M2. Best musical sounding headphones I've heard. Liked it more than the z1r. 

MDRZ7. The highs are very relaxed, and the sub bass is amazing. Great for movies and games as well. To my ears, it has great soundstage depth. I miss them..
