Pros: not the best. yet not the worst. It is the new cheap speakers. imo.

Cons: none

Pros: Cheap, simple.

Cons: Sounds pretty terrible, but I wasn't looking for quality. The headphone jack is also extremely noisy so you still want to plug at the source rather than using the right speaker's jack. You get what you pay for.

Pros: cheap, sound is good for these small speakers

Cons: constantly buzzes at me, off and on every 10 - 15 minutes lately. can last seconds to up to a minute

Pros: We are using these on our son's older pc for pre-school type games. We wanted something small and without a sub. These are a great size and plenty loud enough for our use.

Cons: None for what we use them for.

Pros: no buzz, great sound, built good.

Cons: none

Other Thoughts: this was a good buy

Pros: No buzzing from cell phones or router/gateway.. Good sound..

Cons: Nothing..

Other Thoughts: I bought these speakers because my old ones would buzz anytime a cell phone was around.. These don't do that at all and sound fine.. I don't blast music out of them by any means but for normal computer/music/gaming they are great for the money..

Pros: Cheap, decent sound

Cons: Speakers buzz all the time.

Other Thoughts: Cannot return item because wife threw out original packaging.

Pros: If you are looking for an inexpensive set of speakers, these are for you. These speakers have great sound for there size, can achieve very impressive volume without distortion, are small in stature so they won't clutter up your desk, and are a great price. In addition, these speakers are powered via an AC plug and NOT by USB. Thus, there is no interference for CPU and GPU processors. I've been very impressed thus far.

Cons: The sound quality won't blow your doors off, they are small speakers after all. Also, the LED is kinda bright.

Other Thoughts: Tremendous bang for the buck. I bought based on other positive reviews and am back to verify them. Great deal!

Pros: None, although they do work, after a fashion.

Cons: Speakers have very tinny, almost ringing or echo quality, to the sound.
Additionally, compared to most speakers, they are really tiny and tip over easily, unless placed very carefully.

Other Thoughts: I have bought a couple of other PC Speaker from Best Buy, for about the same price, and the sound quality of those, which are basically a "No Name" type speaker, is still a 100% better than these S-120s from Logitech.
Unless you have a "Tin Ear', which I thought I did, don't waste you time or money buying the Logitech S-120 PC Speakers!

Pros: Very affordable price. Good sound for what they are. Fairly loud as well.

Cons: Short cables. They barely reach from my computer under the desk to the top, next to my monitor, and have to be placed next to each other on one side of the monitor because they can't reach anywhere else.

Other Thoughts: The cable length is more of a minor annoyance, I just have to get an audio cable extender. Still a great set of speakers for the price!
