It is a single stereo speaker/bar costing 12-15€! You can't have crazy expectations and compare it to serious soundbars or speaker sets that cost much more. This is a given and you start with that compromise.
Some things pleasantly surprise you – it plays loud and with a relatively decent sound, but it lacks bass (which typically rattles at certain volume points) and requires the user to play with the sound source settings to achieve the desired result.
It's relatively small in size, with a reasonably sensible cable length – maybe they could have included a power converter from USB (even a cheap one), but cost reasons prevented that (fortunately, you can find a USB port everywhere nowadays).
The decorative LEDs are there just to claim it's for gaming, but thankfully they are relatively discreet and don't distract you.
Simple control switch for the speakers and LEDs (if you don't want them in the end) and a potentiometer for volume (which, as I said, can get quite loud for a room) – exactly what you would expect to find.
Decent enough for their price and relative build quality – if they cost more, say 20€, I would look elsewhere.
For someone who just wants sound for their PC/TV/laptop, has no demands and doesn't want to spend more, it's OK.
