Absolutely! I also love my pair of 599, they’re much less expensive retail but I can really feel the difference in the 560s (weirdly named, the 560s are superior). I think I paid 130 for the 599s.
The 560s have slightly better sound quality but they feel much better to wear for long periods of time. That all said, the sound quality difference is very very small for flacs, so if you find a good deal on 599s and you’re not wearing them for 6-10 hours straight (which I sometimes do) then you can totally save the money.
Both pairs don’t rest on your ears, and they both have ONE cord going to the left ear. My biggest complaints about my beloved Grados is they DO rest on your ears and they have cords going to both ears, which get all wound up and touch my chin/cheek which my ADHD ass does not appreciate the tactile…ness of.
As an aside, my partner isn’t an audiophile and I had them listen to my favorite headphone-testing-song (Tipper’s “Cuckoo”) in flac, with my 560s. I started the song and they’re like “I’ve heard this song before” and by the end their eyes were DRIPPING. I never realized sound could be so… extradimensional, and it really hits goodly.
Quick edit: oh and the Sennheisers have removable cords which can lock in, which is amazing because they come with a shorter cord and a LOOOOOONG cord you can switch out as you like.
