In fact, it can only be used with a wire. The sound of films is nothing, there is enough volume and depth for a small room, but when connected via bluetooth, the sound lags behind, and it was not possible to adjust the delay, it is either more or less, it is completely incomprehensible, so use it as a wireless speaker for a computer to watch TV and u-tube in the kitchen (as I planned) - impossible. As a speaker for an iPhone, it’s suitable, but you need to correct the sound on the equalizer, some songs sound perfect, and some seem to put an iPhone in a gl, especially where there are a lot of vocals and instruments. In addition, you need to constantly turn it off and on, because when the bluetooth connection is broken, it goes into sleep mode and wakes up only if there is a signal on the wire or optics, in order to connect via bluetooth, you will have to press the on or off / on.
The build quality is so-so, if not bad, of course it doesn’t creak and nothing falls off, but the plastic at the junctions is either bumpy or burred, there were also burrs on the charging wire, the quality cannot be compared with a robo-vacuum cleaner of the same company.
