These speakers may not be the top of the line, but for the price, they exceeded my expectations.
I wanted to buy some very inexpensive speakers, without sacrificing too much quality; these fit the bill. I listen to lots of different genres of music, from punk rock to classical; I also listen to talk radio and "books on tape". I am satisfied with the sound.
If you're familiar with the ordinary speakers that are included with most computers, these are a step (or two) up in quality from that. The bass is just barely deep enough and the treble is crystal-clear. If you like to listen to talk radio online or books on CD, (things that don't demand a great deal of bass) these are perfect. If you crave a deep, gut-churning bass, these are not ideal, the sound is just too thin. So, if you like the deep bass of hip-hop, you probably won't be satisfied.
If I had to rate them....and the top of the line speakers were an "A+", I'd grade these (strictly on the sound) about a "B-", pretty good, IMO. (BTW, I'd rate the speakers that originally came with my 2008 "brand "X" computer about a "C-" The sound was thready and shallow...with very little bass to be found and a shrill treble.)
Now, you could (of course) drop hundreds of dollars on some REALLY nice, surround-sound speakers...but for someone (like me) on a shoestring budget, these are great!
They are also super-simple to set up...just plug and play.
If you're upgrading from original, often dinky computer speakers, you won't be disappointed.
HOWEVER, if you're accustomed to high-end speaker systems with deep bass, these may be a let-down and you might do better choosing a more expensive system.
In summary: I very much like these inexpensive speakers!
PS: They are PERFECT for classroom settings, where super bass is not needed. If you're a teacher or an employer with a training office, this would be a great addition to a computer lab.
