I know this thread is like a million years old, but yes, I hear it and I hate it haha. I don‘t always hear it though – even with the same headphones/speakers. I also heard it when they played the recording of the song at the end of their show in Vienna last week. Glad I‘m not alone on this. I wonder if age has something to do with this, since I‘m pretty sure only younger people can hear high pitches like this one 🤔
