These are the wireless television speakers that set up on a chair or couch backrest to provide clear, easier-to-hear audio. The speakers are designed to contour to a backrest and the included transmitter sends audio wirelessly from a television to the speakers. The speakers are tilted inward to project audio toward the person sitting in the chair, allowing users to hear a movie more clearly without disturbing others. The volume adjusts via buttons on one of the speakers and the transmitter and speakers do not require a line-of-sight connection, allowing easy set up. The transmitter has RCA ports for connecting to a television or cable box, while the audio port enables connection to an iPad or iPod for transmitting music through the speakers. Speakers plug into AC with a 7' cord. Transmitter: 4" L  x 3" W x 1" H.
