Edifier R1280DB 2.0 black

The Edifier R1280DB speaker set is an active stereo (2.0) audio system, according to the official specifications provided by the manufacturer, Edifier USA. It consists of an active main speaker (which contains the amplifier and audio inputs) and a passive secondary speaker. Active/Passive: The system is active. The right speaker contains all the amplification electronics and connects to the power outlet. The left speaker is passive and receives the pre-amplified signal from the main speaker. Dipole: No. These are traditional direct-radiation (monopole) speakers, optimized for use on a desk or shelf. Wireless: Yes, partially. The system features Bluetooth connectivity to play music directly from your phone, tablet, or Edifier USA PC. However, the speakers require a cable to connect them to each other and a power cord plugged into an outlet (they do not run on batteries).
