sennheiser 800 is unbeatable for comfort and sound(and expensiveness), but only with proper amplification , the AFX HP out will power it, but not optimally. The MoFI, beloved by influential folk on this forum, sounds wonderful, but many, myself included , find its unique fitting setup unable to be comfortable. ymmv. I have had success using Beoplay 2 (incredibly light ,efficient, and comfortable on -ears rivaling anything I've heard , for 200 bucks, by Bang and Olufsen.
