Relative to other cans, IMO that 10kHz ringing is fairly short lived. Also, that 1-2 kHz depression seems pretty common. In this case I didn't feel like things where wonky or weird. I really like the balance on these. The price of the 500s seems pretty attractive too considering other competitive Cleveland $ range options.

Hey Ultrabike, I had to use your measurement FR plot as a point of discussion in a post I made on Head-fi just now, hope you won't mind. I tacked on a "(c) ultrabike 2014" before posting it.

Hi guys.

Today I ran some tests on my HE-500 with sinegen and detected an annoying "bzz" somewhere between 500hz and 600hz at really loud levels. I haven't noticed this issue in past tests, but I never performed them in this amplitude. What's bugging me is that I opened it right before to clean the drivers. Is this issue inherent to the HE-500, or I just f*cked it up?

A buzz at specific frequencies is probably a bit of dirt or hair caught in the driver somewhere...

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin

But I have opened it before the tests and didn't see any dirt or hair.

I'll look again. What would be the best way to clean it?

Basically just a felt disc, with very specific cutouts so that the open portions of the driver are still open, and the magnet/steel portions are covered (by double-sided tape). The intention is to damp away backwaves from the face when wearing the headphones. Subjectively the upper midrange gets a lot "clearer" sounding with this.
May be a bit late, but still. I did not try it for HE-500, but for some other orthos I prefer to use Blu Tack for this, instead of felt. I feel felt sacrifices some punch sometimes

I found two strands which seemed to belong to the dust filter cloth and took out both of them with an anti-magnetic tweezer. The problem is, when I pulled the second one, the diaphragm came together. Now the issue is gone, but I have a little hole on the diaphragm. Should have never opened it  :'(

Here's a photo of the hole:



Does anyone know if the hole can get larger with use?
