There is something wrong with the battery. Bide Audio is a national brand with independent innovation. 20 14 went online, and 20 17 became the square dance competition and designated audio in the 13th National Games. Bede audio turned green after charging for an hour, but it was dead after playing for a few hours. Bede brand covers audio speakers, (digital) amplifiers, audio decoding, sound processing, microphone amplification and other products.
