    Marv, did you measure this after squishing the pads?

    Yes. Supraaurals tend to be a pain to measure correctly. Worn correctly, I am hearing a bit more bass than what is measured, but the midrange city thing is definitely still there for me. I'll try to measure them again tomorrow while totally squishing them down on the measurement rig

    That definitely looks like a bad seal.

    I wouldn't say "definitely", because it actually does sound that way to an extent.

    That looks like a bad seal / pair, reminds me of the mikros.

    OK, I got a better seal this time. Another set of measurements on the way.

    Will post them later this morning.

    Didn't the Sine have an RLC tuning filter cooked into it? It was set in the upper mids, but what does it do to the output?

    New measurements uploaded. This makes more sense now. Still some midrange city, considering the target curve is somewhat akin to the B&K. Flat to a few hundred Hz and when with a slight downward slope.

    Still looks a bit honky/tinny from the measurements. Hopefully the +3db bass boost from the Sabre dongle balances that out

    I squished in the pads a bit overnight. Yes, still honk city.

    That kinda explains the EQ cable. I'd mod this hard.

    Specifically, what would you say that the target looks like? I generally like to see flat to 500Hz with a 5db downward slope from about 1kHz to 2kHz on my coupler, but as I (tried to) describe here, the target probably varies by headphone due to differing interactions between headphone and ear/head. I would not be surprised if the target for on ears looked different. The innerfidelity measurements looked pretty good.

    The B&K target works well for me on the headphones measurements I do here. I do like 2db extra below 40Hz on top of the B&K curve, but this a personal preference that I would not tune into a speaker I would be making.

    I think it should be a requirement that measurements come with comments and drawings in/on the graph.

    My Impressions! Well, side note first, it's funny watching the evolution of my notes as I kept listening. Started off fairly positive, ended quite negatively. Ha!

    - At first, I thought they sounded pretty good! Neutral-ish. I thought they were a bit rough and metallic sounding, but fairly balanced.
    - Then I started to think they were getting a bit weird and annoying. Brightness, roughness, haze, hiss all started creeping up.
    - Took out of my phone and plugged into Jotun. Regretted that. Bright and rough.
    - Plugged them into my S7 and found some relief from the growing treble rise annoyance, haze, sibilance, etc., but it just kept growing on my nerves.
    - Within the span of 5 minutes I went from very positive to "never want to listen to these again."

    - Lacks ultimate bass extension, yet still has a decent sense of power and low-end presence. I personally thought they extended most of the way there subjectively.
    - Bass is a bit murky and not super well defined. Kind of mushy or rubbery.
    - Midrange is OK, save for the upper-mids, which stick out like a sore thumb.
    - Treble sounded somewhat balanced but rough, hazy, hissy.
    - Decent clarity, speed, resolution. Nothing really good or bad, I suppose.
    - Stage is OK I guess. Better than I thought for such a closed, slim headphone.

    Conclusion - A weird mixture of balanced shouty brightness with a side of hopes and sadness. Unrefined yet decently clear and fast, just not top-tier. I like these more than the EL8 closed but still don't care for them.

    Measurements

    Could only get left channel results. Hm, less bass than expected. Tough to get seal just right on these, but I tried many times and just couldn't get results to look any better. They sound pretty decently extended, just with a bit of low-end roll off. Oh well. Let's just assume bass extends well to at least 30Hz and this is a pad leak. It's the way the upper-mids and treble keep climbing that get to you, then the big suckout in-between that is simultaneously less noticeable than you'd think but greatly contributes to the unrefined timbre. The 9.5KHz bump for some reason did not get on me too much. Peaks like that vary on a case-by-case basis and must be evaluated subjectively. The huge chasm before could somehow make it less unpleasant, somehow.

    Distortion results are OK. Not the lowest I've seen, so it's not pushing my rig to its limits. Bass distortion isn't great, hits 1% faster than HD650. Could explain the murky character or fuller sound than FR shows, or it creeps up because of a leak in the pad seal. Given results from others, I'm inclined to think it was due to an imperfect pad seal. Refer to Marv's or Tyll's results for accurate bass distortion readings.

    CSDs have some ridges, which will also contribute to the unrefined and unpleasant sound characteristics mentioned.

    The FR tells a story! Mountain castles are the best castles against enemas.

    Better or worse than HD 25?
