honestly the only thing i could see being "revs" would be the old black yoke with canare cable ones vs the newer silver yoke with SPC cable ones
i agree...
@soldiersinx
dont know of any internal driver changes or updates as far i know..but i do know they changed the included box 3 times..first it was the big (unusable jewellery box), then they went to the hardcase very useful! carying bag (which i had), and last news i heard is that they again went back to the box..seeing for how much they sell the carrying bag in their shop for i am guessing they included the carrying only because of temperarely production issues with the boxes... as why otherwise would they go back again to the rubbish big box u cant use on the road...
about the cable versions: check this quote:
The new silver cable is built beautifully, though finished with a pretty standard molded plastic connector at the end. The sound is clearly silver. Bright, thin, dry silver. It’s brighter and thinner than the HE-6 original cable (the braided gold color cable), and it’s much brighter than the standard HE-500 original cable (the black Canare). Silver has their fans, but I’m never a big fan of silver. In fact, in this case the black Canare of the HE-500 remains my favorite cable for the Hifiman headphones (It is my favorite cable for the LCD-2 too).

so the he500 was first delivered with the black canare cable (which i liked a lot on my he300) and then it became the silver cable (being silver plated copper as we all found out) later..
and there has been an update for the velours pads...the new ones being less soft...
quote:
The new velour Pads are different not only in the mounting mechanism, but I find the material used for the velour pads are also slightly different. The cloth is smoother and has a finer grain, and likewise the driver cover material is of a different, higher quality material than the old standard velour pads. I’ve taken some close up shot of the old and new velour pads so you can compare the differences.
The sound of the new velour takes on the basics of the old velour pads and improve it further. Yes, if you’ve been enjoying your Hifiman headphone with the original velour pads and you don’t really want to change its sound signature, the new velour is the pads for you. Not only is it more comfortable, but the sound improvement is very real. The tonal balance is mostly alike to the old velour, but this time you get a slight boost in midrange body and even more body on the low frequencies which is just nice. Treble is more or less the same, retaining most of the same airy sound that the old velour has, but perhaps one percent less bright. Now those changes, along with the more comfortable material already makes this new velour a good upgrade, but what I find to be amazing is how the new velour changes the sound to be more three dimensional. Yes! You read that correctly. More 3D! I don’t know how a different cloth material makes the sound more 3D, but as I’ve said, the right pads on a headphone is like the right acoustic treatment in a room. With the new velour pads, the Hifiman headphones have a much improved layering now, whereas they are pretty flat before. Add the beefier bass and mids, and the improved comfort of the new pads, I don’t think I’ll ever be going back to the old pads.
hope this answered ur question
