Black edition. I like this one the most thus far. Looks almost retail, I think. :)

From the insides. Some red materiale stuck and left behind. You can also see the tape. I added a grid to hold the foam into place.

That's a calculated decision, no doubt. They doesn't want them to be too good for the low price. xD

The comfort is the biggest thing, though.

I don't know about the sound changes, but the extra soft materiale is really needed for the added comfort, at least.

Sorry to bump such an old thread.

Where did you get the foam and what kind should I use to mod mine when I get them?

^ I want to know too, anybody?

How thick should the foam be? 1/2 an inch?

I finally got around to stuffing the rim of the pads with cotton instead of foam as I didn't have any foam on hand. this definitely increased the sound stage. I am impressed. I am quite happy with my modded 700's. I have done all recommended mods and couldn't be happier. For the money and a little bit of time these phones are a lot of fun to listen to.

Cheers,

Dan

did you use the loose cotton balls that is for makeup removal etc? Excellent!

Yup, sure did. Stuffed them in one at a time all the way around the rim until the pad was nice and plump.

I have 

SilverStone 21-Inch x 15-Inch 4mm Thick 2-Piece Sound Dampening Acoustic EP0M Silent Foam SF01 (Black)

and Kitchen Liner.

which one would be better to use in the 2nd mod by OP on my HARX700?

My dad RX700's are dead. Left driver is not working, does Jvc sell spare parts? 

just got mine in, i stuffed the pads with the gutted remains of my old monoprice 8323 pads (i use m50 pads on those, hated the stock pads) and really appreciate the added comfort and slightly airier presentation now which i guess is attributable to the expanded soundstage from the added depth

how long is the recommended burn in period on these? also what mods have any of you gone through with to open up the mids and highs? im just curious, im thinking about poking holes throught the felt covering the drivers and probably dampening the cups while i was at it with some lead tape or something, advice???

Did you check the solder?
