The Edifier R1010BT bookshelf speakers sound as good as they look. Equipped with Edifier's own dome tweeters for smooth, articulated highs and ceramic paper cone drivers for powerful bass, these two multimedia speakers are excellent all-rounders that will meet your music, gaming, and TV needs. Wirelessly, two devices can be connected simultaneously via Bluetooth, allowing you to quickly and easily switch between different smartphones or tablets. Additionally, there are two RCA inputs on the back of the active speaker, enabling two audio sources to be connected to the Edifier R1010BT speaker system at the same time. The speakers are perfectly suited for use with a television or computer. Audio sources with a 3.5 mm jack, such as portable music players, can also be easily connected.
