The speakers are amazing on my M1. I'm constantly surprised how beefy bass and clean sound they can produce. Don't recall them being so great on my previous MacBooks though.
Yeah, ok. I presume that by your standard anything less than FLAC on a Bowers & Wilkins Nautilus is unworthy your ears but for us mere mortals the MacBook M1 speakers sound amazing for music as well. It's a massive improvement compared to any other laptop speakers I've heard.
I mean, it is a speaker. Good enough for simple sound feedback on most applications. Music on it sounds bad.
