ahhhh let's see or hear or read
I saw I heard I'll write and you are reading :
so lest start with build quality then:
Plastic body with polished stainless steel backplate feels nice and solid, has just a bit weight to it that gives you the feel of really good build quality. The cable is not so bad either pure Cu with a clear coating on it, rubberised Y split box and 90° 3.5mm TRRS connector for a microphone so you can use ZS10 "PRO" to call your (whomever you want to talk to). The silicone tips: just throw them away and buy nice memory foam tips (you'll notice an instant boost in the low end with memory foam tips).
Now the hard part The Sound:
Sound is a very subjective subject. This has amazing low-frequency rumble
clear mids and crispy highs that will give you the information that you might never heard before plus you'll hear is spectacular imaging slightly narrower soundstage then T2 excellent sub/bass. I was listening to "Bad Blood - Vintage Ella Fitzgerald Jazz Taylor Swift Cover ft. Aubrey Logan - PostmodernJukebox" I clearly heard there was a clip while Aubrey Logan singing those high notes. I mean this IEM gives you those kinds of details so clearly that you'll notice immediately.
the low end is also nice tight and the sub will rumble your eardrums like an earthquake's frequency hits the 7 story building.
In just a few words: Just buy these IEMs, these could be 2nd or 1st best IEM under 4000 hands down after or before TIN T2. If you have T2 also give it a shot.
