(Dampening and sound isolation mod 2 further down) MOD 1 JVC HA-RX700 Foam mod Cut from a sheet of foam this simple mod will not only improve the comfort but improve the soundstage due to the speakers being pushed back further from your ear. The result of a larger soundstage; better musical separation, less shrill highs, more detailed bass, not as boomy. Please post your own mods and suggestions, a couple members here wanted to see about opening up the cans to make improvements, share with us if you've done that along with improvements. -- - Showing the RX700 with plump (pre-modded) left side and flat (stock) right side. - This is all the mod is, a circular piece of foam that I cut out from a larger square sheet, make sure it's as wide as the headphones so it reaches all the way back under the pads. The inner circle the size of the size of the opening, any smaller and it might tickle your ear! - Start to work the foam under the headphone pads, I started at the bottom and worked around pressing it as far in as possible. Make sure it doesn't twist. - Almost all in, keep working it around making sure to push it all the way back. - Once it's pushed all the way in it should just be visible but not obtrusive in anyway, this shouldn't touch your ear. - And the finished result. Two plump sides, nice and squishy! -- MOD 2 JVC HA-RX700 Dampening mod For this I used kitchen draw liner which I picked up from Publix for $2.99, I used half of it for my desk last week and with a bunch left over put it good use. The idea is to line the inner headphone cover which is plastic on both sides, not over the actual driver. This should add sound isolation and cut out those unwanted reverberating sounds bouncing of the plastic. This is still a work in progress and I'll update once I've complete it fully. Right now I only applied this mod to the right side and am currently listening to the difference. What immediately struck me is how much quieter it made the right side, I had to balance out the headphones for the first time; L: 85-90% / R: 100% ~ so it's made the right side 10%-15% quieter overall. Female voices are notably still louder in the unmodified left side, however bass and treble impact is still in full swing on the modded right. -- -Remove the ear pads, just squeeze and pull. Unscrew the three screws and the driver unit will come apart. - A closer look at the driver - Draw liner - I cut out a circle the size of the driver unit, allow a hole for the driver and cut a slit for wire. - Place this in the driver unit, make 3 small holes for the screw housing. - Once you've found a good fit make it stay in place, I used super glue and will not be held responsible if you glue your finger to your headphone. - Do the same for the outer enclosure minus the center hole. And thats it, close it up and screw it back together.. be careful not to trap the wire.
