It appears that the USPS is not going to show with my ALO cable for my new cans. So I decided to brave & give these cans a listen using the Sennheiser "we don't want the headphones to sound as good as they can to people who can tell the difference , because then we won't sell as many of the High End Headphone Amps we're selling now" cable.

They are'nt half bad (with almost $10k of equipment in front of them) (it's funny how you worry more about how things will sound the more $ you sink into your system) It only took a minute or two to hear how the headphone cable is restricting the HFs , you can predict when you're going to encounter the the treble tightness is going to show up by how dynamic the musical phrases are building. The lower frequencies are actually pretty nice for a set of phones w/ no play time on them. I know that the headphone cable is a culprit here as I've heard these sound characteristics from other cans before they were "fixed" by giving them real cables. I can see if someone was listening to music through a DAC that Upsamples they might have to go to the Emergency Room to stop their ears from bleeding.

So , does this mean that I will skip modding these puppies ? No , as good as these phones sound now (& I'm relieved about that) I'm pretty sure they can be exceptional w/ a real cable & a little design correction. The HD800 are great headphones but Sennheiser needed to go a few more steps to finish them . What is left to be done is really next to nothing compared to how very good they can be for this effort.

All matte carbon and candy apple. The red came out darker than expected (more brick than candy), but it's growing on me.

Hopefully squeeze in the time to mod them this weekend

If one were to increase volume to add more bass to balance a hotter treble presence, then yes the mod should even out the FR so you would need less compensation to attain slightly more more bottom end presence at the same gain.  So while sensitivity is unchanged mechanically in the headphone, there could be a perceived increase in sensitivity based on a better equal loudness contour.

I did "Tyll's" version (Creatology sticky back foam, dbl sided adesive sheets & felt & the narrow ring template ) this afternoon . The rings are'nt as "pretty" as I would have liked , but I bought enough of everything for another try or two. This first try is in the phones & I seem to thing I gained another "click of volume" on my Soloist headamp w/o the upper mids getting to much edge.

So my question is are the mod rings that I placed on top of the HPs speaker ring supposed to be slightly smaller than the rings they're sitting on ? (In this version)

All this aside, I am still interested in the "mod kit" when it become available !

Looks nice. Matches my new GS-X.
