JBL One Series 104 is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Nice desktop monitors I was really surprised how good these sound considering the low price and desktop placenent. Dare I say these are the best small powered monitors I've heard? Yes. Especially if space is limited. Imaging is superb, bass is pretty good, though the upper mids seem a bit etched for my taste. Mixes seem to translate well and I also use them for video post work. I would not master music on them, though. I use larger monitors for that purpose. Still, best bang for the buck and very portable.

Rated 4 out of 5 by from Great for the office I bought these a few weeks ago. I used RCA ports to connect a bluetooth receiver, so I can stream from my phone during office hours. They perform very well. Bi-amped speakers have all the power they need to produce low distortion sound at all volume levels. They play a across a very broad spectrum and all types of music sound great. These are ported, so the low end comes through even at low volume levels. I rated 4 instead of 5 as they lack ( just a little) punch at the low end. It is probably asking too much from such a small package. My preference is for the bass to be impactful even at low volume. Don't be confused by this though, they produce a very rich sound from a decent mp3 file. Great value.

So I don't need an amp for this? I can just plug it straight into my computer? Why does only one speaker have audio jacks?
