    I've applied a KISS-alike mod except instead of Creatology+Dynamat Extreme combo I used thick layer of BASF Comply foam. (In form of Comply wraps.) The chunks on the sides were left as is mostly, with a slightly increased thickness of the hard foam layers.

    Interestingly enough, the use of this kind of silicone foam is much more effective on the magnet and nearby surrounds than creatology + dynamat extreme. It's slightly smoother sound yet as a result of additional highs peaks absorption. Not a huge difference but I'd take anything. I did not cover the magnet hole with foam, only the whole magnet and unvented plastics on its sides.
    The extra thick creatology-like foam layer improves bass handling a bit still too.

    Main problem is that this foam is expensive if bought as Comply Wraps. I think it is BASF BISCO BF-1000 foam, can someone find a reasonable retail source for this?

    I've got a pair of V1 black driver HD650, and I'm curious to try out this KISS mod! Should it result in the same effect on my headphones as it does with the white drivers'?


    Sorry I haven't gotten an answer for you! But, would you be able to share some pics? You said you used a thick layer - - Did you stack the Wraps on top of each other?

    Bit of an old post so apologies...

    Does this mean that for earlier HD650s you did the KISS mod but without attaching the folded foam disc at the back, as well as performing the coin mod at the front? Or are you referring to something different?

    I did the M mod for prior iterations of the HD650 which seemed to have a more damped and boring character.

    M mod does mean complete removal of foam in the back and coin mod.

    Well, it's not that super expensive, and there are equivalent foams - compared to the silly sorbothane feet for instance where there is no equivalent and a cheaper material will be inferior. You can use any soft sound and vibration dampening high density open cell foam for this pupose. I just had way too many wraps on hand.

    Just did this mod on my HD6XX and I have a ton of Dynamat/Creatology leftover (already stuck to each other, uncut). If anyone needs some I'm happy to ship your way for the cost of shipping.

    I'm just realizing that I can probably fit enough of this to mod a pair in 1 envelope, and I'm not going to charge people for the price of a stamp.

    If you live in the US, I'm happy to throw some in an envelope and ship your way for free. Just PM me your address.

    edit: lcmusiclover I have some in an envelope for you and will ship it out today/tomorrow

    I have enough left to mod ~4 pairs, first come first serve!

    Edit: 3 pairs left
