designed Rush for use with AUX-in devices and headphones. With SKAA, the receivers (speakers/headphones) are in charge of selecting which transmitter to listen to. There’s no pairing — instead use Bond Button for easy transmitter selection. Rush utilizes a 3.5 mm stereo audio output jack, volume control buttons, remembers up to 10 of your favorite transmitters, has 35m indoor range, has low latency, and can be powered from any USB port. Use up to four receivers at the same time with any one SKAA transmitter. It ships with SKAA OS 2.4, and works with all transmitters running SKAA OS 2.1 or newer. SKAA transmitters work with iOS and Android mobile devices, Mac and Windows computers, televisions, and just about any product with a line output or a headphone jack.
