Hi, I'd like to find new IEMs with some requirements. What is needed is BA or BA-based hybrid, comfort+isolation+form factor of about KZ ZS3 level (I had an idea to put the innards of my dead Urbanfun Hybrid into ZS3's casing, but l don't know whether it's possible). The sound I'm looking for is detailed and with all frequencies present (I won't shy away from equalizing, especially the bass). For reference, I find ZS3 to be way too warm and lacking detail, Urbanfun is very good overall, Piston 3 is somewhat tinny and lacks bass. Removable cable is preferable, though not vital. The price level should be under 50$, but extendable to 100$, if something extremely suitable is available.
Does anyone know if something like this exists in the Chi-Fi field? I'd appreciate any tips.
