If you do cut any holes in the pads, start with 2 small holes and make incremental changes as needed. I think the four holes I made are just slightly too much. But, hey, they certainly don't sound as laid-back or thick in the bass now as they did before. (I went a few days without listening to them after these mods, did a bit of listening again last night.)

FWIW, BMF's T50RP measurements display the same artifacts with the FA-003 pads and are somewhat ameliorated with the use of tape.

Good to know. Won't bother taping until enclosure damping is in place

It's probably more important to seal the area where the donut is stitched to the flap than to seal the flap to the enclosure. I wonder if one could use ring cut from a medium sized balloon instead of electrical tape, since the latter will most likely peel the pleather off with time.

Have any of you tried simply taking off the back panel and listening? I'm digging that configuration right now with HM5 pads. With stocks pads, it moves the peak down to ~6k like purrin noted. Listened before I measured and thought it was a lot brighter. it's actually not according to the plots. Guess I'm more sensitive around that area or whatever. Red is no backing.



HM5 + no back are rewarding to my ears. Much more transparent midrange. Enclosure weirdness seems to be mostly gone. Decay plots seem to verify so. Actually, they indicate the headphone is storing a lot less LF energy but there's some hashiness that appears around the upper midrange when the back is removed. Anyway, here's the FR. Blue is no back.



Have yet to try taping the pads down. And all these plots have TP in front.

Wow, that's really interesting. It seems that the back+stock pads causes some reflections that boost the treble? It's bizarre that the HM5's don't have a similar effect. Either way, when I was listening with the backs off, it definitely seemed like a warmer headphone with boosted bass. I guess that's because I am sensitive to treble and I was actually noticing the treble decrease more than the bass increase. I added a detachable cable jack to the pair that I had and I gave them away as a gift for Christmas. I'll need to get my hands on another pair (seeing as my HM5 pads finally showed up) and put a red grill on the back  :)p15

The TH02's good bass qualities stay in place with the backs removed. So I think these drivers would be a good candidate for a transplant into some sort of open enclosure. If only I had a CNC mill on hand...

Yeah, that would be unlistenable for me. Your pair is still showing a good 5dB more at ~8k than mine ever did  :-00

Oooopsss.

I still had my testrig set for on-ear measurements.... (was making Kramer mod measurements on PortaPro when these finally came in)
Corrected now... have learned not to 'rush' things.  :-[.
