My ideal volume on a PC is 50/55 with the youtube on max so the range is more defined. Other times I'd use a Bluetooth and speakers depends on if they are plugged in or charged You ?
My headphones are loud even at the lowest I can have it to be, So I tend to keep it at 10/100 unless I'm walking home and want to jam out, then it's 50
My default is usually mute. I up the volume as needed. Unfortunately, my current computer doesn’t make changing the volume or muting/unmuting easy, so I have it on at the level where I can hear zoom comfortably. I hate that I can’t easily change it. But it’s okay since I’m on my phone the majority of the time, and can always have that on mute.
Right now only Lofi is on so 75ish (Headphones- the volume is at 25ish) but usually I have 2 or 3 playing in the background at different volumes. It’s white noise for me.
