In fact i have to agree with luisdent, the Tenore sounds very similar to a HD600 with more sub bass and a smoother treble. My FA003s (for anyone that wonders they do indeed sound very similar to the HD600s) have a more peaky treble than both of those and a noticeable dip in the low mids which makes them sound cleaner but also leaner than they should. Anyway, to me, a Tenore with a proper roll off in the sub bass area would be perfect as far as fr goes.
X2 on the possible HRTF / perception variations, that's why I try to assess IEMs relatively to each other whenever possible.
Speaking of which, my RE600 and IE800 are the exact same units that Rin measured, and I can tell that even my "reference" Tenores' subbass is more elevated than the RE600's (while staying well below the IE800's).
That's insane, because I had the re400 which isn't as warm as the re600, and my reference tenores are in line with the re400 but sound lighter in tone due to the extended flat treble.
So far this is what I have found:
- Of 6 tenores in my possesion, 5 of them are within 1-3db of difference in the bass, with seemingly identical mid/treble. The other is a greater variance in bass (less bass).
- Super gluing the vent made zero difference in any sound whatsoever.
- Taping the vents completely with scotch tape didn't seem to make any audible difference at all. I'd have to test more, but I didn't detect anything noticeable.
- Based on impressions compared to other earphones I've heard myself, some people are indicating the bass on their sets is at least 6db or more greater than my sets, as I can easily compare the bass level of mine and their tenores based on my knowledge of the reference comparison earphone.
- I've never heard even more than 1-2db difference in any other earphone where I've compared multiple pairs, although I've seen it in the mh1c on graphs (only other case).
My thought on the venting would be that it's possible I didn't fully seal everything or the tape didn't properly block air, but the glue and tape appeared fully covered and bonded. So I don't know why others are experiencing otherwise, unless they are perceiving a change because the expect it. Otherwise, I would need to seal the top vent with glue, which I'm not going to do.
This whole comparing has led me to start EQing the ostry to match the tenore. Although not identical, I only need to cut the ostry's bass around 180-200hz by only 3.5db with a somewhat wide q value. The treble doesn't extend as high, but otherwise it is just a high quality in my opinion with a slightly different tone and less high air, but still great. The biggest pain in my arse is the fit though. I'm actually getting royally sick of getting a good fit with the tenore. Sometimes it's easier than others, but I have no idea why. It simply fits right away while other times I have to mess with it a lot to get the pressure and whatnot exact.
For this reason alone I think the ostry kicks butt. However, being so used to earphones that have some isolation and seal to them, the ostry almost always feel "wrong" because they seem like they aren't sealing good. But that's just the design. No tips or effort whatsoever allows them to seal better by any reasonable margin. But if you are in a quiet environment and get used to the feel of them this isn't a problem at all. In a loud environment, they still don't sound the best with isolation as you hear outside noises, but the bass does well and almost sounds more reference as it is slightly masked by ambient noise.
Overall, I prefer a mix of the two really, so I think these will be my two main iems until I find something better. But as much as I thought my search would end with the tenore I think I'm going to continue searching for something that meets all criteria for me. This almost sounds like the uerm, but I'm not ready to spend that and risk bad custom fit. Ugh.
That's my two cents anyway. I'll keep listening to messing with everything, but so far I still think these are the best two values I've ever heard...
