Zero:2

Didn't rate the Zero:2 at all; among cheap sets they've tried, the Tangzu Wan'er Red Lion was one of the only ones they'd go back to.

Bought the Zero:2 a few months ago as a starter: the bass is too light for them and they hurt the ears after an hour; directional audio was fine once a mono setting was turned off. Not bad, just not for them.

Owns the Zero:2 and finds the bass solid once the tips seal properly; uses a generic liquid-silicone tip because few stock tips seal for them.

Uses the Zero:2 with swapped tips, a JCally dongle and EQ for portable listening: very cheap sound that's hard to beat under $80, and in noise the detail gap to their Hexa disappears.

Bought the Zero:2 as a first IEM, with Apple's dongle and lossless Apple Music, and wasn't impressed: vocals and mids sound ordinary and the detail is nothing new compared with their earlier earbuds, even after trying EQ. Wonders whether the Chu II would have been better.

“Vocals and mids were “normal” and detailing was nothing that I hadn’t experienced before, like i don’t know if i just spent money or wasted it on market hype.”
