The running time of six to ten hours specified by the manufacturer shall be achieved. This may vary depending on the volume. Charging takes about two hours until the speakers are fully charged.
The BP2003 loudspeakers deliver a good and clear sound for a price of approx. 60 Euro. The bass is very good here and the rest of the frequency spectrum is not neglected either.
With the help of “airflow technology”, which is an open tube about 15 cm long from the outer part of the housing to the interior, the frequencies of the lower spectrum are generated. Remember this by closing the opening with your finger and opening it again.
