If you need them for everyday computer use, music, movies, gaming, it's a very good choice. The only negative is a little big for a common desk.

For their price, they are satisfactory, nice design, moderate bass - strong treble.
With the Realtek Equalizer, you can customize the sound as you want.

Beautiful appearance, with enough wattage for USB powered, the convenience of USB power so you don't need extra sockets but... the ones I got were defective, only one was working... It wasn't the USB port's fault, I tried it on another computer, even with a separate power supply. It just seemed like I got the faulty one.
I don't know if they were generally problematic (I didn't get the same model as a replacement) but the sound was very low for their nominal power, even at maximum volume. Additionally, at some point they started interfering with my other USB devices (the wireless keyboard wasn't working).
I probably won't buy USB powered again. Even for very low requirements, I don't think they have enough power.

For those looking for a set of 2 speakers for a stationary setup and don't have high sound demands, it is a very good solution. I didn't encounter any issues with noise, the speakers play flawlessly.

Relative good sound quality without distortion, nice lighting on the volume button but I only give it 3 stars for the annoying buzzing noise that the speakers make when they are turned on, which is proportional to the volume. It is annoying when the speakers are on and there is no music playing, but when there is sound (music or from a video) then this buzzing noise is covered.
