I just ordered the KZ ZS10 PRO IEMS based on the great Z review and all the other amazing reviews.
I know that cheap equipment will only ever sound so good, but I find that the highs at any decent volume are ear-piercingly harsh. The snares and high-hats in rap music make me feel like my ears are going to bleed, and the voice and guitar in metal sounds like tinny garbage.
Also, I have to use an EQ to bring down the rather harsh high-end on my Philips SHP9500s, and I had the same problem with a set of the Samsung Gear IconX bluetooth earbuds. Unless I put them on the bass-boost setting everything sounded like a compressed waterfall.
I know that all this gear I have described is rather low-end stuff. (Also, The DAC/AMP i’m using for the SHP9500s and tried with the ZS10s is the Schiit Fulla 3). But still, I don’t understand how so many people aren’t hearing what i’m hearing.
Do I just have hyper-sensitive ears? Do I just listen to music twice as loudly as everyone else?
