Think you will find the K 712's to be comfortable both sound wise and physically. They adjust to one's head easily with an adjustable band and are relatively light weight. They come with 2 detachable cords (esp the 9" orange cord). I have a pair of A-Audio's also which compete with Beats Sound wise are good, but I found them heavy and tend to squeeze my head making them uncomfortable after a while. These seem to rate high with gamers as do Beats.
While the K-712 don't give the "in the gut" punch effect of a high powered sub, you can definitely hear the lows, esp pedal tones. Then, too, it depends on the sound source. Normal (if there is such a thing) audio from my H/W setup sounds very realistic (again whatever that is) while
some recordings sound less so. All depends on who recorded the music and what they used. Myself, I don't prefer exagerated high or low end music, but more toward "realistic/natural" as you would hear in a live performance. Just mine and my ear"s "humble" opinion.
BTW, my favorite live recording mics are my AKG 414's. I find with real pipoes, using heavy pedals, 32' etc, can get boring if used too much when there are so many lighter, beautiful registrations available on many sample sets. I know some organist's prefer lots of full organ but there again, that's why we have choices.
(I still think using a 64' stop that very a few organs have (like the Wanamaker), makes it sound like a helicopter coming in for a landing..
