BTW their gray-black color is back in stock. I probably ordered by now over $100 in V-Moda cables for all my headphones, but ended up with only white, red, and purple as my choices
is there a way to permanently fix the channel imbalance due to the cord? (no soldering please)
Huff...
I make this my last post for the while, for those that may or may not need it.
Once again, the only worth to this graph is the relative changes.
As the legend shows, this is the effects of vent sealing or the lack thereof. I went by full vent slots and no partial slots, but the results are almost linear. The effects of covering vents as far as FR graph does little to be properly documented from 1kHz onward, but just remember that FR graph is not everything.
I think my headache is just making me more sensitive to bass. Sleep I go.

I've consistently found that closing cup vents produces less bass quantity but better bass quality, and the effect is linear. In fact, closing off 3 slots and part of the 4th is linear and significant by 1 mm increments. With my mods, I get the best SQ with no more than a 3 mm bass port in just one cup vent/slot while other modded sets sound better (to me) and measure better by completely sealing all 4 cup vent slots.
BTW, try measuring with the baffle port open vs closed. I think you will find that closing the baffle port increases bass quantity.
If you're ambitious, you could measure the interaction effects of: baffle port open vs closed X pad type X number of cup vents closed X with/without acoustic foam, X amount/type of dampening X xyz!I haven't calculated the number of permutations but it's huge. It would be informative to know exactly how much, if any, SQ variance is accounted for by each component so we could discard components that don't add any benefit. Then again, I suppose it's possible that a component that does not work in isolation may work synergistically with other components.
I just received my T50RPs in the mail this morning and had them playing for about an hour now. The mids are definitely great. Everything else, not so much.
I'm going to give them 50-60 hours of burn-in before I mod 'em, mostly because I've never modified anything before and I'm terrified of breaking a component. It'd also prevent the annoyance of modding it to my preference and then having the sound change on me from natural burn-in, so I figure to get it out of the way first.
Personally, in my opinion, the biggest "ouch" area to really be careful of is that thin speaker leads that connect to each of the drivers. When you have the baffle removed from the cup and flipped over on your desktop -- just keep paying close attention to those wires. You don't want to pull the baffle too far away from the cup and stretch the wires to break them or tear them off of the solder tabs.
I think if one really wanted to be protective of the wires when doing this task, they could apply a bit of duct tape over the solder spots where the leads connect to the driver and then another piece of tape over where the leads connect to the jack box on the incoming port. This would act as insurance in the event you did "tug" on the wires, they would not break free.
Best of luck and enjoy!
