Yeah...it’s fine for short use but really starts irritating for long sessions.
$20 cheaper.. not a whole lot but still. Would be great if the program is a success and more drops would be done like this.
Oh boy, just did the KISS mod to my 6XX. The word snappy come to mind, and that ****ty graininess I hated so much is reduced appreciably. This was a last ditch effort to salvage these before I sold them, these ain't going anywhere now
Thank you for the detailed reply, really appreciate it.It cleans and tightens everything up a fair amount. They always seemed to sound fuzzy or grainy to me but the kiss mod has helped clear it up a considerable amount. The bass is more articulate and not as muddy, it just sounds more energetic. I think the bass extension is a little better too. The tonality is unchanged, at least to me.
It makes sense when I think about it, the mod entails adding dampening materials on part of the driver magnet, and around the inside of the housing. The magnet has been known to fall out part way through this mod, it's just not secured well apparently, so I could see how that might affect the sound. A magnet rattling around, not enough to really hear, but enough to alter the sound. If you look through the grills, you might be able to see the "spider", it's a plastic cage that holds some foam over the back of the magnet, the spider is also thought to introduce some unwanted sonic characteristics, but mostly you have to remove it to do this mod. Mostly the mod is just putting dampening material (I bought a sample kit from a company called second skin, it was under $10) over part of the magnet to secure it properly, and to dampen it. Then more material is added around the magnet as well. The foam that was there before is actually two foam discs, one disc is folded in half and you use a little bit of the sticky dampening material to glue it to itself, and a little bit to secure it to the magnet. Overall the hardest part is really just cutting the material, I used a hobby knife and it was still kind of annoying. There is also another recommended mod that entails removing the thin layer of foam in front of the drivers and cutting a small hole in it by tracing various kinds of coins as a reference, aptly named the "coin mod". This apparently brings the treble forward a bit, but I didn't want that so I abstained.
I get the impression that sennheiser just pumps these things out. I wouldn't say the build quality is bad, just missing that last bit of polish that I feel this mod provides. If really like them as they are, you might not bother, as once you remove the spider, you can't really put it back in the headphones, unless you glued it or something. A good amount of the mod could be done without doing anything irrecoverable, but I don't know how much is attributed to putting the material over the magnet itself, and not just the surrounding area.

Hmmm, maybe they picked up on some common complaints, ie the bass, graininess, and the veil and tried to address those. That seems to be what modders are going afterwards for sure. I've never heard the 660s, but now I'm a kind of interested. Tyll's article shows the interiors, and the driver housing is quite a bit different, maybe they addressed some issues there? Then again the driver is different too, so who really knows except sennheiser.Sounds identical to what a HD660 is.
