Haha, thanks, Marv, for doing the measurement. Now I know what frequency response I was able to get out of those drivers.

Yeah, I meant to approximate the tonal balance of the SR-009 with this headphone, though the level and quality of the mid was more my personal preference. I wanted a headphone that would do vocals justice on a variety of sources.

The slight channel imbalance, I think, is actually due to the earpads. That's why I left the ESW9 earpads so that you can put those on. Please try another measurement with the ESW9 pads, if you don't mind, because I think swapping to those will have a pretty sizable effect on the graphs.

On a side note, CEE TEE, I have finally decided on what headphone to work on next. I think it'll be the Beyerdynamic DT770 Pro Limited Edition. That one won't break the bank, and it seems like it's among the very few full-size headphones that won't necessarily require an amp. The other factor being that it's relatively easy to obtain a new pair still.

I had thought of Denons, but those are really hard to obtain now, and given that I still like Beyer's overall tonality, I think the 32 Ohm DT770 is a safe choice. Well, we'll see!

Along a similar vein, you can try cracking open a Beyer COP and try balancing out mods with the adjustable bass vent.

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

Going to do this today. Hopefully I will have some time. Still fighting this bug and have to deal with BS work related stuff.

Well, I got the DT770 Pro 32 Ohm studio version instead of the Limited Edition, since I've heard that the LE sounds "darker" and "smoother" than the regular version, which... actually doesn't sound all that impressive to me. It's easier to attenuate than to add, so if this one lacks treble to begin with, I don't think I'd be able to add that back in.

And I have never owned a DT770 before, but... playing around with this one, I found that there is indeed a small opening in the back for the bass. Plugging it does reduce bass roundness by a significant margin (much like with the ATH-W1000X that I used to own), so I decided to leave it alone.

Not sure how good the COP would sound... but I'm really liking the tonality of the DT770 now. The same mods that brought the midrange of the ES10 out so much seems to apply to the DT770, too, so maybe it's universally applicable?

I'll see if I can detail the process and what I'm using to mod the DT770 now... since it seems like modding the old Beyer drivers can bring about pretty interesting results!

My DT770 actually has COP drivers (because the COP has T50rp drivers instead  :)p17)

I still get that weird trebly peak in the DT770 so I've got some acoustic foam in the back and a piece of felt in front.

With ESW9 pads.

Wow, thanks, Marv!

It's great to see CSD so clean.

And that sort of confirms my suspicion about the ESW9 pads. They seem to increase upper mid ever so slightly.

My DT770 actually has COP drivers (because the COP has T50rp drivers instead  :)p17)

I still get that weird trebly peak in the DT770 so I've got some acoustic foam in the back and a piece of felt in front.

I'm hoping I could have another pair of discerning ears to listen to my DT770 now. I seem to have been able to reduce the sharp peak with more specific shapes of felt.

Though the reduction came at the cost of clarity... so I'll play around with the shapes more and see if I can find a common ground that wouldn't reduce clarity.
