It's a shame that not many people have commented on my Paradox headphones. At least 20 people have heard them.....
If you do get that second, I'm always willing to give them the Paradox treatment.
No kidding? 20 people.. come on folks! I've got great respect for your ears so I'm very surprised to not see impressions. I'd love to have you mod these to Paradox specs. Since I've got a handle on my mods it won't be a problem to duplicate on another set of T50RPs (I'l be ordering soon).. I'll be PM'ing you in the near future, LFF..

Oddly, I used only 1 layer of paper tape over the backs of the naked drivers and all I got was tin can alley sound. I figured the glue on the paper tape essentially rendered it impermeable, or non-breathable, and resulted in constricted, poor sound quality. I glued the stock white driver felt in place and all was good, again.
I could not tell any visible difference between generic and name brand paper tape so I went with the generic brand. I suppose there could be a permeable difference not discernible to the naked eye so I'll stop by the drug store and buy some 3M NexCare paper tape for repeating the test.
FWIW, I found that 1 layer of craft felt and 1 to 3 layers of Organdi over the naked drivers produce the same massive bass slam and bleed-over into the mid-range that you describe. It sounds like you have found a viable substitute for the stock white driver felt. Way to Go, FlySweep!
My exact concern too.. I was pleasantly surprised that it didn't constrict the sound. It's certainly on the brighter side, but tinny it is not. Re: the bleed.. it was one of the toughest things to control with the vents, for me anyways. I simply cannot stand bass bleed into the lower midrange or any manner of a mid bass hump. I'm very happy to find the tape keeps that all in check but doesn't affect the sub bass. If there is anything people might desire from my mods (speaking of which, I need to come up with a name), it might be more bass slam. Right now, it's tight and quick. I'm going to work at tuning this with additional layers of tape (in various regions of the driver back) instead of modding the felt covering the vents.

3. 3 layers of 3M NexCare paper tape on the backs of the drivers (after removing the stock white driver felt).
4. Plasticine in the baffles.
5. Stax O2 ear pads
If this is correct and if 3 layers of 3M paper tape equates to the stock white driver felt, then the variables I need to test are whether or not there is a difference between the stock black bass port felt vs. stiff 2 mm craft felt on the bass ports, ear pad "rolling", and add more Paxmate to cover any exposed areas in my cups.
Spot on, BMF. I'd say 3 layers of 3M paper tape is a hair thicker than the stock, white felt. 2 layers is closer, if not identical to stock.
If I had to describe the sound of my mods, I'd say tight, bass.. no midbass hump.. balanced midrange (that's very slightly midforward).. and a clean, crisp airy treble.
I'm listening to John Scofield's "A Go Go" right now and the tuning seems perfect for the recording. I can hear Billy Martin's slightest nuances in his masterful percussion work. Scofield's soulful, funky guitar has never sounded so lively & colorful. Chris Wood's bass playing is tight and possesses excellent speed and clarity. I can clearly discern how well my mods control the midbass hump with this recording too cause Chris Wood goes ham on the upright. I heard it heavily dominate the sound & bleed into the midrange with the craft felt backing. It's much more in line with everything else right now.. but presence is not sacrificed.
The other thing that jumps out to me is the instrument separation. It sounds like I'm in the studio with these guys hearing it played live. Billy Martin's drums in particular sound sooo damn good! Every flourish and minute touch sound clear as day and accurate. The tonality of the drums is spot on.. like everything else. Medeski's keyboard playing is so fleshed out.. I just want to hear this on repeat all day.
Also, I've got the v-moda 3.5mm cable LFF mentioned a few pages back, on the way.
