LOVE the FOAM modification . . .
Graphicism . . . so much so that when I went to MOD my RX700 with foam I thought I had - but did not and was I bumming.
Then I remembered . . . in a drawer in the kitchen where about 2 years ago I had some weatherstripping for doors and windows. WOO HOO!! Not only was this foam a GREAT mod (as proposed by
Graphicism back on July 9th 2012 in his original post - KUDOS again by the way,
Graphicism) but it was PERFECTLY SYMMETRICAL (as in round) and is a FANTASTIC modification.
While I could not find the original bag for the foam, I did visit the vendor's website and found the SAME product . . . 3/8 inch x 20 feet Poly-Foam Backer Rod. The name Rod makes it sound rigid, but it is not - it is very flexible and it retains its cross-sectional shape (area) when wedged into the ear pad (cushion) space.
Here's a tiny pic of the product . . .
Here's a tiny pic of my
Graphicism-inspired moded HA-RX700 . . .
Did the same thing with a new pair of Senal's I found on eBay for less than $20 . . .
Dunno if Menards (stores) are in everyone's state, but here's the link to Menards website . . . http://www.menards.com/main/doors-windows/weather-stripping/wj-dennis-poly-foam-caulk-savr-reg-backer-rod-weatherstrip/p-1914351-c-3624.htm . . . if not Menards, then Home Depot likely has a similar product.
Thanks again,
Graphicism.
