Compared to modded triple flanges, with the custom sleeves, the treble is like being controled, very well/efectively. Now I can hear the upper high (10kHz and beyond) better, and the upper mids or the lower high (4-7kHz), seem to be attenuated a bit, so no more harsh/sibilant and this bring a better overall treble clarity.

Just wondering how much more benefit from customs, considering them are about $165 here. And why were you not satisfied with the flanges if they sounded best? Just curiosity? |
Ok, mine is not the UM56s, and it cost just USD 36 (converted from MYR), so cost doesn't seem a big the matter to me.
I am really satisfied with the triple flanges, but, the custom sleeves do bring a better, cleaner and well controlled overall sound quality. Matched with warm sound signature of D10, I could not say anything more

Wow, I tried an old pair of gray bi-flanges I had from the Ety ER4P, and they sound excellent. Even better treble extension than the Klipsch gels maybe. They certainly are great with isolation. I am going to mod down the tris I have left from the W3 as well, into bi-flanges with short stems (to meet the bottom of the larger flange) and see if they sound any different. But on balance, the Etys are very good. It's so weird how these odd tips work with IEMS they were not even made for in the first place. |
Aha!, now you get it
. The problem is how to get the sound from the transducer as clean/direct as possible to the eardrums. Our ear's shapes do make thing difficult for universal tips. Our ear canal is not straight like the cylinder, but have curves and angles where the sound wave may canceled out each other, or even worse, it may resonating, which we may perceive it as sibilant or harsh. sound. Plaese correct me if I am wrong here.

And as you say, not recessed treble, but just laid back and never harsh, which is excellent. |
Yes, there is no or very little sibilant/harsh with custom sleeves. So I can enjoying long hour listening without fatiguing or ear ringing. Yes, I do missed the 'brightness' but, I can adapt to it, as my new sound preferences.
Thank you.
