I haven't noticed any changes with my pair after 100+ hours.
You don't know how glad I am that I've found this headphone to be a keeper.
Me too :)
I could probably fall asleep listening to my Q701. No, it's not because it's boring. It's not, but just that it's never fatiguing.
Same here LOL. For the same reasons. I could never listen to my other headphones as long without hearing something annoying/fatiguing and putting them away. At lot more of my songs are getting listening time, songs that I used to skip on other headphones because they caused fatigue when listening to them.
I also never had any issues with any of the treble bothering me. If it ever does it's the fault of the recording.
It would take a really bad "hot" recording to make the Q701s produce offensive treble for me.
One thing I noticed is that this stock cable on the Q701 must be really good. When switching to something else, the sound just isn't the same. It's especially noticable during gaming. I tried two other copper cables and the mids seem a bit leaner and just different. Kind of less musical and more analytical.
Hmm...hopefully AKG matched these with a decent cable that doesn't bottleneck them.
I do know that when I amp these with my E9 or a portable amp, there is just something missing with the mids. Still good, but just not the same.
I noticed the E9 had recessed mids with these as well. Like the mids "left the stage" a bit. Don't know if it had something to do with the E9 output impedance, or if thats just how the E9 sounds.
BTW are there any Q701 fans that also love the HD-598? Both I like about equally. Q701 is technically better, but HD-598 is a keeper. Q701 is just a lot more clear and detailed. HD-598 is a bit better for relaxing and not wanting to analyze your music.
I bet I would like these, maybe I'll pick up a pair someday...
