I lift my left ear headphone just to see any difference but this is totally bs , the tune is altered itself even if you listen it with one of your ear you'll still notice that flux or the gap , the sound is itself like that not that our brain is creating and working on some altered sense
😆 normally I just delete arguments, but I find this one too entertaining... I think you may have some bass boost or other enhancer running, which is creating extra beats.
