Over time, the battery loses capacity, a year later, a full charge was enough for 37 minutes, a nice bonus 2-year warranty - the money was returned. Has some pros: Nice materials. Reliable fastening. Decent sound from both speakers and microphone. Hold the signal well. Has some cons: Stupid software - ICUE, the charge level can only be viewed by going to the settings, annoying voice alerts. Cheap built-in battery - as a result, low autonomy.
