This is my personal pair and it actually does sound less bright than UERM #2 (of which I will post the measurements later)



The re-iterate: Plots will not go past 9kHz for various reasons. Burst decays will be used instead of CSDs. Right channel is intentionally dropped 1 db.

Reminder: stuff past 9k is probably inaccurate. Especially the sharp peaks. Those peaks are the effect of the ear canal and the IEM. Personally I don't think they are heard as measured.

V2 = new compensation model.

But your measurements don't go past 10kHz. These are worthless.  >:( WTF!?  :-Z





















Sorry....couldn't help the typical head-fi'er response.  :)p2   Awesome job dude!  :)p10 :)p3

wow.. that is impressive. can't wait to listen to it ..measurements aren't everything you see. Its finally what you perceive. Everyone hears differently.


There, that's a better Head-fi response haha ;D

Question on reading the burst decay graph:

For the sub-50hz frequencies, there seems to be a dip, followed by a peak. If it happens with headphones isn't that usually attributed to resonance? I think I'm reading it wrong :(

The FR looks great though. I definitely plan to get UERMs soon.

No idea what's happening there in the sub frequencies for the burst decay. Figure I'll keep posting until we see correlate patterns with sonic qualities or determine it's just random.

I feel like I'm missing out with IEMs. No matter what I do or what type of tip I use, I can never get a proper fit or seal. Oh well...still cool to see you doing IEM measurements! These look pretty damn nice.

Marv, are these response curves compensated? If it effectively measures flat at the entrance of ear canal, I can't imagine how these earphone can't be perceived as tonally neutral.

Still, they are my favorite phones.  And, the ones that I would choose- if I had to pick just one flavor.   :)p5

Excited to try these out at the August meet. If I like them I might sell off my other equipment to fund the purchase of these.

Yes. They are compensated based on modified diffuse field EQ. Been doing them by ear comparing with other neutral references, i.e. my desktop near-field monitors, and with input from people who I trust. There may be a few tweaks here and there...
