Since it seems that for bassier sets, covering the vents brings it closer to the "reference" sets, and reference sets not really being affected by covering the vent, it would imply that the bassier version was the intended tuning. Specifically, why design it with a vent that affects the tuning of the low end if the intended tuning is allowing zero airflow out of that vent.
The only thing that I could think of that would lead toward the "reference" pair being intended is if they decided to retune it and found it cheaper to seal the vent rather than make shells with no vent. But this is slightly undermined by the shell supposedly being aluminum, whereby the vent is likely drilled at little to no extra cost rather than having to remake an injection mold for plastic which would be an order more expensive and would make this scenario plausible.
Perhaps, although the reference bass level sounds intended. I know some might say "how can you know what it's supposed to sound like, you didn't design it", however, it's like a painting of something real, if it has a strange purple tint you would think the photo was fading and not the original reference state it was supposed to be in. You could argue that was a stylistic colorization, but if it's a picture of something that is clearly attempting to be very realistic, that would just seem "off". O.k. strange example, but with the tenore, the frequencies above say, 400-500hz are practically identical to the er4s relatively speaking vs other IEMs. That level of treble accuracy seems really odd if the bass was meant to be very boosted. It would be like etymotic saying, man this this is so accurate, but let's give them bass like a beats earphone.
So to me, when I hear the supposed "reference" sound, everything sounds "just right" and smooth across the spectrum. When I hear the bass heavy version, even in a small amount, it just sounds like someone didn't like a neutral earphone and added bass with eq that didn't belong there.
Alas, this is just all theory and nobody knows but the designer/manufacturer what it's supposed to sound like. The best we can do speculate. However, either way, the reference set sounds great, but it's hard to know if you'll get that sound when you buy one. Even if you like the bassier sound, you wouldn't know if you are going to get that sound either.

Anyway, the bass on the ostry's is different and the jack is bent. Brand new, sealed well in a nice presentation. My kc06 also has a different bag than the one I have on loan. Not sure what that means? A revision perhaps? The model I have has less bass and ironically sounds a lot more like the tenore. Anyway, what the heck? Is it impossible to buy a japanese iem, who are known for quality, and get something consistent? Maybe their cheap iems have less quality control than our cheap iems? lol I don't know. I'd keep these as the sounds is even better than the pair I'm testing, but the bent connector worries me. They still work, but I don't want it putting pressure on my jacks....
Ostry is a Chinese brand. As for bass differences, maybe the new driver needs to flex a little, give it a few more working hours and compare again. I had similar issues with multiple mh1c pairs but after a couple of days of use they all settled to the same exact bass.
I think it was actually the tips straight out of the box were very dry and almost powdery in texture (not literally), so they weren't sealing "as" well as the already poorly sealed worn in tips. :-P Comparing them now they seem identical. At least as far as I can tell. I'm also thinking I'll keep them. I might just use a cable extender "just" in case the connector would possibly harm a jack being bent slightly (it's not too bent, but still worries me)...
