Maybe, though I don't notice this personally, as different youtubers have different default volume level anyway, so I often play with volume anyway.
What I do notice, is frequent noisesss, e.g. at 2:48
, sound s is the biggest offender here in words "this
" and "things
t" which startss kinda painful to lissten after 30 minutesss or sso.
Come to think of it, maybe it sounds that noisy because volume had to be turned too loud.
