Apologies, I got this post originally confused with another. Thought you wanted audio for your scanner lol. My bad. That being said, For the price ($25), that Soundcore speaker is crazy good for music too and if you buy two of them, you can even get stereo sound. They aren't the loudest thing in the world but they aren't quiet either. Pretty good bass, clear lows and mids and as I said, you can adjust the EQ to your liking, but the presets aren't bad for general listening - The default is great.
But they're bluetooth only. However, they have these cheap dohickeys out that you can plug into a 3.5mm jack and they emit a bluetooth signal so that's a good alternative if your devices don't have bluetooth. Not sure how good they are, but if you looked into a bluetooth speaker like the Select 4 Go, might be worth a try! if you just want to replace your PC speakers, a USB bluetooth dongle would be fine.
