Quality, ease, and future-ready design

With aptX Adaptive and HD audio, the Audikast 4 aims for crisp, responsive sound and minimal latency. The sleek, compact body helps keep a tidy TV setup, and the device is designed with forward compatibility in mind, offering a path for updates as devices evolve.

In real-world use, viewers may enjoy private listening during late-night movie marathons, dialogue-heavy scenes, or shared entertainment with family members who prefer different volume levels. The two-mode approach lets you switch between single-user private listening and a multi-user Auracast setup as devices permit, all from the comfort of your couch.
