Well, it is certainly true that if you a playing a Beetles album backwards different individuals may hear some sounds differently. But, if you haver heard an orchestra tuning the purpose is for all of them to hear the same notes in the same way. There actually is a “right way” to hear music accurately. But sure if it doesn’t matter to you, that’s OK too. I’m an amateur musician and it really does matter to me.
My hearing aids are wonderful for conversation, for music, not so good. I’m using M90s now, better than my others but still not accurate.
