    Quick subjective impressions:

    Less of a resonance play than Purpleheart. The wood seems more solid and doesn't add color. The least colored among the different cups. More refined and more dampened than Purpleheart or Mahogany cups. Wonder if this is the effect of the denser Ebony? Noticeably smoother lower treble. Doesn't have that slight sharpness of Mahogany and to a smaller extent the Purpleheart. Small sharp peak past 10kHz. Adds a bit of definition and increases audibility of noise such as tape hiss, but this seems preferable. Overall still a member of the X00 family.

    Measures flatter overall with smoother transitions compared to the others, but I don't want to make a hard call. Measurement is really tricky with these because of pads there can be significant differences if one is not careful with exact placement on the measurement rig.

    I tend to have more confidence in CSD measurements. They focus on the upper mids and treble where I see less variability to bass (which can vary depending upon seal - getting just the right about of seal can be tricky). Compared to Mahogany or Purpleheart, definitely smoother. I like what @CEE TEE said to me on it sounding more refined.

    Wow! My Mahogany cups are going in the wood chipper. JK. But seriously great job to Fostex and Massdrop for not sitting on your hands but instead continuing to improve on an already great sounding headphone.

    Ugh, I'm going to have a forest of th-x00s if this trend keeps up, but I guess that's what they were going for :)

    Thank you for the measurements!

    What's next, bog oak?

    This is going to be the last variant of the TH-X00.

    Ebony is definitely the least colored. Purpleheart has the most interesting resonance play with the good and that. Mahogany is somewhere in between, but closer to Purpleheart. Collect them all. Haha.

    Posted this question in the drop thread on MD but I figure I'll ask here too in case anyone else is wondering: Are you going to have all three variants at the Wikia meet this Saturday? It'd be great if we could do a direct comparison (and also get a preview of the PH I have on order).

    These comments pique my interest. I haven't yet heard an TH-X00 - the mentions of some sibilance (or "sparkle" as some may say) in some reviews scared me away from ordering and I haven't been to a meet that had a pair. Can you comment on subjective impressions of the Ebony in comparison with, say, HD650, HE-K, or any other reference for those of us that haven't heard the other TH-X00 models? :bow:

    To clarify, our statements have all been "last wood variant". This is because if some time in the future, we find some amazing special material that does a better job than wood, we aren't stuck because we said "never again".

    From a product development perspective, Christian has a lot more irons in the fire and while the TH-X00 is great, with the release of Ebony we feel the line is complete and it's time to move forward with other Fostex projects.

    Fostex TH-9xx please. I'm willing to bet the majority of the cost of that headphone comes from the Japanese labor making the wooden cups. Get that out of the way to drop costs and use the TH-900 driver, with some returning, and we got a winner.

    Oh man... so much juiciness to read into in this one post.

    The other thing I heard about Ebony is that it has a 30hz sub-bass peak and the Purpleheart has a 50hz sub-bass peak so Ebony has a deeper Bass extension.

    Indeed. The measurments here seem to bare this out. Not a big difference, but a bit more extension on the ebony.

    Could be even a partial mm shaved from the inside of the denser ebony cups causing this. Or perhaps a more solid coupling lowering Fs. Just guessing.

    Subjectively does the bass sound any cleaner or tighter than the Mahogany?

    The measurement posted on massdrop show lower bass distortion, though not by a lot.

    There wasn't anything that made me feel the bass was significantly different form listening to it, although I didn't have very much time before I had to sent them off.

    From a measurement perspective, the Purpleheart has the highest distortion. I believe the drivers are the same, so the logical conclusion is that the purpleheart wood is resonating.

    Here is the mahogany.

    Here is the Ebony. More or less the same (it's difficult to reproduce distortion measurements exactly) as the Mahogany, but with the exception that higher order distortion is much less on the ebony. Again, probably a property of the woods. From measurements very early back of Grado cups, I know mahogany will tend to resonate at many different places. So these findings are not out of the ordinary.

    What would be most interesting would be full spectrum plots for specific frequencies excited (35Hz, 70Hz, 1kHz, 3kHz, etc.). The wood does make a difference and it is measurable (with the right measurements). I think @Will was trying to explain this to people: that the wood does make a difference and it's not color or dye or placebo. It's pretty real.

    Oh my... those are stunningly beautiful. That all black look is just so slick. The November 15th ship date seems about average for Massdrop, but this will give me ample time to hype myself up for these.
