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.”
