The speaker goes into sleep mode after about 20 minutes of inactivity, which is extremely inconvenient when used with a computer, for example. You have to manually bring it out of this state by pressing the buttons or changing the volume. In general, there is no flexibility in setting up the speaker itself, there is no way to disable multiconnect, which is also very annoying, because the speaker is constantly trying to connect to all familiar devices, plays sound from a neighbor’s phone, makes a million connection / disconnect sounds. The sound quality is excellent, but these moments are very frustrating.
