Mac mini volume

The sound from the Mac mini won’t be that strong to begin with because they use a laptop speaker and it’s very tiny to begin with!

To get more volume I recommend using external amplified speakers. Regular computer speakers will work or you can plug it into one of those Bluetooth portable speakers with an INPUT port. I did this with my MBP and a really cheap audio cable (I think they are 3.5mm plugs).

I did some research on the Creative Pebble (original one) and they are USB powered so there’s not a lot of power. In this article from PC Mag, they say “it’s a pretty limited system” and they are a “notable upgrade over laptop or phone speakers.” To me, that sounds like a very low bar to jump over. For more volume, you need more power like what the Bluetooth speakers or plain amplified speakers that you plug into the wall for power will give you.
