XXX: What depth of submersion will it withstand?

YYY: When I was on Titanic, the music continued to play, even when I went underwater... the battery holds well, still plays music, keeps the depth of 3,700 meters calm, warm the body well.

ZZZ: Noah, when I was diving into the Marian basin, they kept it calm up to a depth of 500 meters. I don’t know, my skull is under pressure.
