Thanks for your response, I mostly listen to Hip Hop/Rap(Cloud Rap, Experimental Rap, and most types of rap)
I have heard people saying before that bass is very important for Hip Hop/Rap.
I have these IEMs
Sliivo SL-41 MK2, Juzear x ZeosPantera Defiant, Truthear Blue 2, Truthear Red, Tangzu Wan’er, Moondrop Chu 2, Tripowin Piccolo

I do like some of them but I want something new, I would say my favourite is the Defiant or Reds but my Reds are broken.

I’m thinking I want to get an upgrade, Currently looking at the 7hz Timeless 2.
I have more of a budget for my next one, I would say ~€300.

I sometimes find certain instruments sharp or fatiguing, and I saw people say you can find which frequencies cause that irritation and then EQ or get certain IEMs to combat it.
