It was purchased for the purpose of providing background voice acting in an office that is 50m2, and it performs adequately in this role by 5 points. The volume is practically set at four out of ten divisions, and because it is set at such a low level, the speaker is pumping. and it's not only the sounds; the sound is extremely rich and detailed, and the bass is elastic. When compared to the H/K Go play mini and the Kilburn 1, this one has a significantly more "purebred" sound. We primarily use Bluetooth to listen to online radio; we have not yet experimented with AUX. When the "Marshall Bluetooth" application was installed, the column immediately updated the firmware to version 6.1.2. The Marshall Bluetooth program provides the capability to modify the equalizer, adjust the illumination of the divisions on the "knobs," and a variety of other little chips. There is no use in splurging for a Kilburn 2 100% model if the speaker is only going to be used at home and portability is not required.
