Ok so, I just bought these 7z zero:2 to replace the cheap old earphones that came with my previous phone (an Oppo A72, if this can help you) and ngl I'm a bit disapointed. These zero:2 are my very first real non stock earphones and I don't know if I have to get used to the difference or else but they sound very high and shallow, my stock ones are much deeper and clearer.

Tbh, the zero:2 sounds like the ones I remember playing with on my DS 10 years ago, lol. (I obviously exagerate a little, but this adds to how they sound to me)

Did I do something wrong ? Is this how earphones are supposed to sound like ? Did anyone got the same issue ? Am I just an idiot ?
