This is a Behringer portable PA system. Despite its small size, it has a 40-watt output and is a high-quality loudspeaker. The sound quality is good, making it suitable for music. An AC adapter is required as a battery is not included, so it's best for indoor use. The body was originally navy blue, but it has been repainted with gunmetal paint. Operation has been confirmed. A microphone is not included, but a mini-jack adapter for a microphone is included.
