How do we determine if ours are part of the "recall"?

If your drivers are made of opaque yellow-white plastic (rather than translucent pearl white plastic), then it is from the problematic batch of new units with treble issues.

new (treble issue) drivers
 

 
 
 
old drivers (no issues)

Well done HiFiMAN.
 
This quick response nipped the issue in the bud.
I noticed a number of people turning away after hearing about the mixed impressions of the "r3."

Thank you for the info.  So I took mine out (just received them brand new last week and hadn't had a chance to get familiar with them yet) and after removing the ear pads, mine are really in between those two colors.  They're nowhere near as white as the v2 pic and have no translucency, but mine are more of an off-white color with a slight yellow tint (sort of like you mixed the two photos you posted):

Kinda hard to tell. It looks like r2 from that pic.

That's 100% rev 3. I know because it looks exactly like mine. Pretty easy to identify. Rev 2 drivers have zero yellowish tint and are translucent enough to see through.
 
My drivers for comparison:

^^I'll defer to the expert^^

When did you buy it anyway? It might help to determine if its r2 or r3. But I do agree that it looks more like r3.

Well crap, lol, I literally just got these and have to return them.

 
I received them on October 3rd, 2012 which was Wednesday of last week.  They shipped from the dealer on September 27, 2012.

Great customer service Hifiman! Best of any company I have ever dealt with.
Concerning the treble peak in rev.3, I noticed it upon my first listen, but it isn't that much IMO. Unfortunately I hearing issues with higher frequencies and it is uncomfortable after just a short amount of listening. I am sure people who are treble heads might actually enjoy rev.3 as it offers bright highs, as well as excellent, well extended lows that I have not heard in any "bright" headphones. But that is just my opinion

Thanks jerg for the driver info.  I freaked out when I saw the replacement post from HifFiMAN. Mine were bought less than a month ago and I had no idea how to ID the rev 3 from rev 2.  Turns out I have the rev 2.

I don't think treble-heads will like this defective treble. It has a ringing peak in the treble, rather than a smooth and overall elevated treble, which is arguably bad quality. It's analogous to saying 'bass-heads will like bloated flabby bass'.

Yeah, I guess a better way to describe rev2 vs rev3 is, rev2 = clear white, rev3 = bone.
