So, You are:honestly that's the only area the zs10 wins in. All the rest go to the it01.
I don't think my opinion is far outside the mainstream if at all. That's literally the one area the zs10 is better than the it01 in, and I feel in general is where the it01 is a little bit average.
Overall, the it01 is a better pair of IEMs.
Keep in mind I'm also comparing the zs10 with a balanced cable versus the it01 balanced as well, so that in itself may open up the staging a bit. If you're willing to put a lot of time and EQ testing into the zs10 they're very good, but are a little rough around the edges to start IMO. You can order the it01, open them and put them directly in your ears and they sound very good to start.
1) using balanced cables to compare them.
but...
2) what source gear are You comparing with?
3) what amping You use?
4) what tips do You use and what size?
5) what music You mainly use to compare them?
I am:
1) using single ended cable with neutrik hq 90`jack (cable measures 0.2Ohm for R/L/G)
2) using HW & FW modified DX50 @ FLAC-only, <0.5 Ohm output impedance
3) using HW modified DX50 amping @ high gain ( 3.1V / 80mA juice per channel)
4) using Auvio S size wide bore tips
5) using mainly progressive rock with great masterings like Steven Wilson, Porcupine tree, Gazpacho, TOOL; Seven Impale, Dream Theater, The Mars Volta etc.
IT01 has best low-mids I`ve heard in IEM so far (even comparable with Asura 2.0 earbud, which has very good mids) with no bleed between mid-bass/bass/low-mids.
