Good on ear headphones

Since I really enjoy the formfactor and sound of my KPH30i, I wanted to get something else of simlar size.
The KPH30i sound great, but sometimes I could use more treble and resolution in the upper frequencies.

So far I’ve put Grado SR60x and Sennheiser HD25 (with Yaxi pads) on my list. Are they a worthy upgrade or are there better options?
I mostly listen to Classical and Kpop, so they should have just enough treble for classical but not too much that my ears get murdered by badly recorded kpop tracks.

If you want a bit more treble you could also try putting KSC75 drivers on a Porta pro headband with Yaxi pads

I don’t really like the KSC75. My model also has weird ringing in the mids
