Summary: To me it seems like one of the speakers may already be blown, and they dont even get that loud. Main complaint is that there is little to no bass. The quality of these speakers really isnt much better then the audio I get from my HTC One cell phone, these speakers just are louder. I would not recommend these for audiophiles or really anyone who wants to enjoy music.
Summary: Purchased three sets for the office and they all work fine. My set makes a low amplitude, high frequency sound just on the edge of my hearing, and it's really irritating. However, the computer's sound card could be at fault and not the speakers, because every set of headphones I've plugged into this computer have also picked up some form of interference.
Summary: Nice computer speakers for the money. Well made and powered by a USB connection (which is awesome). The sound is about what you'd expect from $10 speakers- shallow and a bit tinny with not much channel separation. However, these are solid performers for low demand locations such as an office. Recommended.
