Those who write that the sound is very bad or install the speaker incorrectly (should not be placed close to the wall or in a closed space on a shelf), or listen to complete slag in low quality, or bought a non-original one, or a bear stepped on their ear. The build quality is unpretentious, the sound is powerful, rich, you can hear all the details, it perfectly plays almost all genres. If you need great sound, then you don't need to listen via bluetooth via smartphones or from computers with cheap sound cards, the sound source must be of high quality and via wires. And even if you listen from Internet services, but by wire, the sound is more than decent.
