That's weird because I don't really notice the HD-598 being congested. On most music I don't even feel as if the sound is too grainy. I'd have to be really looking for it.
Don't want the grain and better build quality? Get the K601!
I also had the modded 555 in the past because always disliked it. I'm not sure how close to the 595 it is.
Went from disliking the 555 to loving the 598.
I gave away my HD-555 to my brother along with an MP3 player years ago. I guess they love it.
I think the 555 holds the record for the longest I've owned a headphone. Maybe 10 years? Seems like it.
When I'm 80 I'll probably still be on here raving about how the DJ100 and 598 were so good "back in the day"...
By then they'll probably have portables for $100 that sound better than the HD-800.
I hate to say it, but I haven't listened to my 598 in a few days for music. K601 and HD-650 is it! I guess I need two sets of ears.
I'm hoping if I cook my K702 for a few more days it's stupid annoying treble will tone itself down.
I can't say it enough, but the HD-600, 598, K601 and even the K240 Studio are the rare headphones that they seem to be good for people who only need one headphone for EVERYTHING. This includes multiple genres, movies and games. I think the 598 might be the easiest for more people to like.
