The ASTRO A50 Wireless Headset delivers top-of-the-line acoustics, ergonomics, and durability that hardcore gamers demand. Experience legendary sound and performance without the inconvenience and restrictions that come with wires. The all-new ASTRO Base Station features a 5GHz wireless transmitter that provides clear, low-latency voice communication while making headset pairing and charging simple. For even more flexibility, the optional A50 Mod Kit allows users to swap out the headband and ear cushions for improved noise cancellation and comfort. A50 Mod Kits are only compatible with the New/Gen 3 A50 Headsets and not any other headsets, including previous generations of the A50. The A50 headset is not included in the purchase of a Mod Kit.
