100+ Head-Fier
yes, the 650/6xx sound extremely realistic because of the body of the notes and timbre it can produce. also, the level of micro detailing is v strong despite there not being an overwhelming treble. the 650/6xx is just a special headphone
I picked up a 6xx a few months back and was blown away, specially in the vocal department. Really surprised me how much I liked them, super intimate but great.
