I dont remember the size-i bought a few different sizes from OSH- they sell by the foot. Here's a pic, I used qtips to hold the ends together. The tubing costs next to nothing -be sure to buy too much in case of mistakes
pics added to main post of A1 pro.
These have a v-shaped sound curve with emphasis on the deep bass end for a nice thump, works well with a portable source. These are small on-ear headphones, construction seems solid, like a nylon plastic
Ok -I tried some tape mods- its a little difficult as these headphones are chambered and vented already, JVC put some thought into these!
Anyway, Isettled on a little thermal tape on outside cup, it helped control vibration a little, also did some metal tape inside main driver chamber, helped highs come out a little. Adding metal tape to outside chamber did nothing. Overall these mods made the headphones seem slightly louder, I supposed a lot more material could affect...
Hah-we need to make one! I don't know if I mentioned this previously- In modding my JVC rx700, I discovered that lining the cup with metal pipe tape brings up the highs like a metal cup headphone, and using thermal insulating tape adds more thump to the lows (like using Dynamat, but much easier and less $$)Do we have complete diassembly pics?
SZ1000 VS. DARTH BEYER -
I recently got a Darth Beyer (Beyerdynamic dt770 pro with large wood cups), these are bass monsters so the comparison had to be made!
disclaimer- EQ was used a lot, the Beyer is well broken in, the JVC has maybe 100 hrs at most.
haha- neither one is very portable and both take power to drive....
The Beyer wins on clarity, has a much smoother sound all the way through the spectrum, though some may prefer the...
