Best set for deep bass
Looking for IEMs with deep bass for high-BPM techno tracks
One function - Principles of unity
My current IEMs are Letshuoer S12 Pro, KZ Castor bass, and Kbear Rosefinch. While the Castor and Rosefinch are great for sub-bass heavy genres like hip-hop and trap, I find the S12 Pro's bass much better for the techno tracks I listen to. I don't know how to explain it, the other 2 feel less sharp in bass compared to s12 pro on these tracks.
Are there any IEMs with sharper/deeper bass than s12 pro? My budget is around $200, but willing to stretch to $400 if there's a significant upgrade.
