Best with headphones. I wanted to try a little experiment with sound here. I muffled my mics with headphones and then typed on this Razer keyboard. It kind of feels like the keyboard is inside my head. Also, I know the keys have been rubbed off. I use this thing for hours every day for work.
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
