Lol the Quark DSP is a literal Harman Target hugging IEM.... Don't know where you heard it is similar to the the OG Quarks which have that hard to miss peak in the upper midrange making things sound shouty

I'm only looking for EQ presets since certain sounds (like snapping drumsticks together, clapping, snapping fingers) hurt my ears.

Everywhere I look, I read that it's very close to Harman, but certain sounds make it painful to the ears. Can you tell me what frequency I should cut? I'm using Poweramp EQ (parametric type).

Try lowering between 4khz and 7khz. That range in Harman seems to have the most problems for people

Ah so you want an EQ preset for the the DSP that lowers its upper midrange shout and treble sibilance...

Are you sure you're not listening at godforsaken levels of SPL. Also are you inserting them deep enough in your ears.... If you're doing all the above correct item stuff then this EQ I'd send via your DMs should help. Check your DMs

I'm gonna try.

Ok. I'll update once I try your preset.

Thank you so much for saving my ears and IEM at the same time. Your help saved a life. 🙏

Glad it worked out
