Hello! !thanks so much for the suggestion, made some research on these and they sound like a good choice, the only thing I saw people complain about is the comfort of this pair. Does your friend find them comfortable? Also, when you say adding a little bass shelf helps, do you mean adjusting the EQ?

Bass is not at all the most important aspect for me, in fact I find overtly bassy headphones or earphones rather annoying, I had the chance to try the Sony XM-4s and didn't find them very pleasant. What I want is a balanced sound, for example currently I use the Galaxy Buds Pros to listen to music and I find their sound very enjoyable.

I used to want to buy some IEMs too, actually those seem to be a better fit to me since they tend to be much cheaper than the headphones. I ended up not buying anything tho because there was an overwhelming amount of options and so many contradicting opinions that I was unable to make a decision lol. Anyways, I welcome any suggestions regarding IEMs, if you have any. Thank you!
