A way to make use the audio output jack, no "hi-fi" though!

1. open vlc media player
2. roll up the mouse for volume to 200%, I think this the maximum
3. the audio jack output is audible on ur ear-phone

Note. Don't know any harm to the chip though;
2. no "hi-fi" though, ha ha!
3. use an amplifier is the suggested way.

Pis put out a "line level" signal on the 3.5mm audio jack. I've found that to be adequate for headphones. For anything bigger, I use self-powered speakers and don't have any issues.

If you want better sound quality, get one of the many audio HATs that are out there.

Yes. ok for headphone but not ok for cheap earphone.
