This is so strange iv listened to this countless times and I still hear the same sound every time of heavy rain pouring down and even when I remove my earphones to check if I’m hearing things it’s completely quiet no sounds at all but when I place my earphones back into my ears same sounds again heavy rain pouring down anyone hear that?
Sounds like your device might have some kind of filter enabled (surround enhancers, Dolby, Atmos, DTS, bass boost, Beats, echo, reverb, etc.)?
