Don't understand how these can reportedly be called harsh (batch difference again?). My pair is revealing, but never to a point where it blatantly accentuates sibilance or harsh frequencies. These are actually very revealing though, lower bitrate or poorly mastered songs will show their flaws very easily with these.
Anyway, been comparing these back to back with the EX600 and while they both sound very different, they're very close in technical proficiency. Amazing how JVC managed so much with a 8.5mm driver.
Also, these are hands down the best I've heard with brass instruments, even more so than the FX700s. Strings on par with the 700s with a slightly different flavor that's more in the analytical side.
i agree
ive never thought them harsh but they are very treble abundant and if you feed them crap they will punish you accordingly.
thing is when the stuff is badly mastered you cant do anything about it.
I would love to be able to hear the 500's in comparison to my 700's. As far as hot treble, I've found the (real) Sony Hybrids are the perfect cure for those sensitive to it.
Which tips are the best for FX500? Which offers good isolation without compromising the SQ. The stock tips are just horrible.
@noobass456: The BEST sounding tips I've found for the HP-FX500 are the HiFiMAN/Head-Direct RE Series Bi-Flange clear silicone tips. Excellent extension at both ends of the spectrum, and easy-to-clean, durable silicone. 2 other great sounding tips are the COMPLY P-Series, which are dense foam (but less so than the SHURE Olives) and are "airier/softer" sounding than those other goodies, the very bass-enhancing, and extremely isolating SHURE Olives. Sometimes I find the Olives make my canals feel too "full" and that the treble/upper HF part of the audio spectrum is too congested.
Good Luck

Are there any physical differences between the old batch vs. the new batch?
Ok well I got mine and I think they're new batch. The bass doesn't distort on high volume, and the treble isn't really harsh. Though on high volume it's a *bit* harsh sometimes.
Just wanted to add that I've been using these for almost two years now and they've been the best personal audio I've ever had. I got rid of everything else I have including over the ear headphones as a result. The bass can be overwhelming at times with a good fit, but I wouldn't have it any other way. Accurate? probably not. Reminiscent of live concerts and such? Hell yes.
I've been kind of curious if anything better is out - I'm sure many would say the 700's fit the bill - but what else?
I've had FXT90 and enjoyed their sound except for harsh treble on some tracks.
Seems like the 500 have similar sound signature?
How do the 500 compare with the 700?
