If any Apple engineers are reading this, for the love of god please make the low battery notification volume adjustable. Thank you.
I bought a pair of Sony WH-1000XM4s on sale a month or two ago in large part for the 30-hour battery life (yes I could use wired headphones and have an infinite-hour runtime; I have a very nice pair of Sennheisers for that. I don't always want to).
