I did make every effort to EQ the Zero 2, in my case I am using Auto EQ, as the 1st layer of my equalisation. For both the Zero 2 and the T10.Fair enough- but the stock FR are very different between the Z2 and the T10. I would suggest adding a bass shelf to the z2 , a peak at 2.2k and a pretty broad peak at 6k would produce something a lot similar in terms of presentation between the 2 once you get the levels pretty even.
For me the priorities for buying any IEM should be fit/ comfort primarily along with a stock FR that is smooth and low distortion to allow easy EQ.
The driver tech would be somewhere near the bottom of the list

Apologies for explaining what you may be already familiar with.
In AutoEQ.app, I target the same target curve, the default IEM target curve, in AutoEQ.app, to correct both IEM's, which is the best I can do, to make them sound as similar as possible. using an automated tool, so this takes out of the equation, my own skill or lack thereof with EQ.
The corrected versions of both IEM's the Zero 2 and the T10, I listened to for many hours. My detailed notes are where I also narrowed the playing field by using the same ear tips, so the fit was as identical as possible, is here :
Tips and cables- for IEMs
Side note. A pox on any company that ships a cable with the l/r markings on the 2 pin connectors on the inside as its mounted on the iem. What are you thinking? Those little L/R markings on IEM's are one of my pet hates. Does your wife use nail polish? Dab a little of the red nail polish on...

I have gone back to enable the EQ on the T10, cos it adds a certain clarity, but EQ is not essential to the T10, only a bonus.
The main difference when auditioning, the T10 and the Zero 2 are :
1. Clarity, with the T10. I am hearing layers of the stereo mix, that I could not hear or even be aware of with the Zero 2. With the T10, certain things are quite impressive, I hear all kinds of low level instrumentation, and notice immediately that lots of lead vocals on major albums, by major artists like Beyonce, are NOT center locked, contrary to expectation, but slightly panned to one side, and in some songs, her lead vocals are dead center. No other listening device I have heard, including speakers, was as revealing of such details. No other listening device, clearly with ease, highlighted such minute differences from song to song. Every song I hear, and these are songs I have heard critically on EQ corrected speakers, for at least a decade, continue to be a revelation, cues which I know well, are now not just cues, but I can pinpoint the exact panning locations, in the left to right horizon, from where each cue emanates., in the stereo field. The stereo presentation of the T10 was so wide, I had to implement a custom stereo width narrowing solution, to reduce it. I'm an audio engineer who mixes music in my home studio and also for live events, and done so for a good while. So when I heard the T10, and I already have pretty decent headphones like the AKG K702, which I have owned for a decade, it was a leap forward, for someone who thought he had a pretty good thing going. Nowadays, when I mix live events, I no longer take my AKG K702's with me for monitoring, that duty is now handled by the T10.
2. Frequency band - The T10 in comparison to the Zero 2, stretches the upper and lower frequencies in both directions, giving me not higher levels, but more. More sub bass, which is not existent on the Zero 2, and more twinklies like above 10 K, which the Zero 2 struggles with. The audio therefore sounds more like real life, cos I can simply hear MORE of what's in the audio.
3. Bass - The T10 goes not just lower, but lower with definition, being able to enjoy the texture of the kind of bass in use in a song, acoustic bass, synth bass, electric bass, rather than just hear the low frequencies.
4. Vocals - the only word to describe these on the T10 is "crisper". Diction, and intelligibility are heightened, with the end result that I can lower the volume and still hear with clarity what is being said, spoken or sung words., so the listening experience is less fatiguing, cos I can hear all day at lower levels of loudness. Mine are on my ears for upwards of 12 hours every day, for the last few months.
Maybe I got lucky, or have a golden sample T10 !!. Won't know until I hear another T10, or another planar, or some other supposedly high end IEM. I fully expected to be impressed with the Zero 2, based on the low distortion measurements published on ASR, which is why I bought the Zero 2, but my copy of the Zero 2, is not in the same league as my copy of the T10, in spite of all uniform efforts to EQ them, to the same frequency target. Two different worlds, and I would say, anyone who has done this comparison, on a good copy of both of these IEM's, I would expect them to come to the same conclusion as I have.
