there is a thread about Jade Audio you can actually just post there instead, and they are surprisingly good, sounded more mature than KZs, with great extension end to end, wide soundstage.
to be honest, compared to all your signature there, I can live with 1 EA3 because for me the EA3 have no wrong here, just little improvement here and there, for me TFZ no 3 lack of midrange forwardness, V90 also the same, KB100 is great but sub bass extension and porportion between sub-mid bass is better in EA3. and compared to cheapo BAs in KZs, they sounded more mature. Separation and imaging also very good, even the hybrid multidriver budget IEM have slightly edge because of driver numbers. Fiio FH1s is more or less EA3 in disguise. They said that they made this EA3 for improvement over FH1, more like a test to me, if they succeed, they will name them FH1s, if they didn't, well does't hurt Fiio big name.
