1. Doesn't know how to play music from Spotify/YouTube out of the box (well, at least something third-party, except for the meager . Music music library).
2. Not the best quality MONO speaker, which means that all modern music loses its stereo volume, which is equal to half the buzz from music. Buy a second one if you want a stereo pair (only this is a strange decision, I will explain why below).
3. The speaker is excellent for playing speech content: bluetooth videos, podcasts, audio books are generally fire.
But only the most unpretentious listener will listen to music on this device.
First, I repeat: this is a MONO speaker.
Secondly: all the reviews on the Internet lie about the sound. In reality, the frequency response is very curved: the tops are turned up - by ear, in the region of about 10-15kHz, the frequency peak is raised by some thin band, a very unpleasant rattling rattle-resonance. No built-in equalizer can fix this, because. this is a design feature of the speaker.
At low frequencies (bass), everything is clear: the speaker is small, there is no bass - the physics of sound, you can’t argue against physics. Of course, you can play around with finding the location of the speaker in the room, catch some kind of modal support for the standing waves of the room, but few people will bother like that.
