Hi, all
My experience after a week with new EX800ST:
I changed cable to:
https://nl.aliexpress.com/item/4000706847547.html?spm=a2g0s.9042311.0.0.1b564c4d73hfdT ... which is a pretty stiff 1.2 m cable (no problem as it does not tangle), but proprietary connectors, angle for around ear and sound and quality and LOOK are all good.
I use the IEMs with large black Spinfit 240 as Complys Isolation 400s took away bass (???), have not tried other or stock tips yet.
With Spinfits 240 I feel the subbass rumbling vibration with the tape mod with a VERY small hole.
I like that raising the bass with the tape mod and EQ does not take away mids at all. With any other IEM I have (Jade EA3, KZ AS16, Sony XB50AP) the mids disappeared after raising bass to my required levels. I can listen to these on very low volume and the WHOLE bass spectrum sticks.
As a source I use Samsung Galaxy A40 + Hiby Music player + Topping NX4 DSD in DAC mode at 11:00 AM max. volume + bass boost ON.
Maxxing the Hibby's Bass extension slider to +100 and increasing 32 Hz EQ to max. gives me the proper bass for my currently favourite drill rap in 128Kbps MP3s LOL. With the other above IEMs the bass would start to distort very quickly, but 800ST eat the whole snowboard hill.
Now, for outside, even during when I skateboard in Amsterdam (hard 101A wheels and brick-like tiles), I have absolutely no problem with isolation or fit.
Compared with abovementioned 3 IEMs:
Jade EA3 Subbass is VERY present but only because of weak bass or mid bass, EX800ST has it all
KZ AS16 Obviously no subbass with BA, and also weak bass, even though fast (good for hardcore and fast guitar punk and FPS gaming)
Sony XB50AP Bass distorts very soon and they sound like shower room, no mids at all after raising bass
It looks that these are endgame for a long time for me
Highly recommend, the massive, limitless (till ears say '!!!NO!!!') and clear textured high quality bass is incredibly addictive. The rest of sound spectrum just sticks at comfy level.
Enjoi!!
