I’ve used AS10s for the last 3 years. Previously tried Shure, Sennheiser, Westone. None of them worked for me.
I recently bought a set of GR i6s and they’re now my go to.
As acebass mentioned above, volume is lower than the KZ but once I brought that up the overall clarity and bass response is excellent.
I may be biased as I’m a GR addict, but these IEMs are brilliant.
