The new ASTRO A40 TR headset and MixAmp Pro TR feature increased user customization to adapt to any environment. Ready for home use, LAN play or the loudest pro tournament, you can transform the A40 TR from an open-back to a closed-back noise canceling headset by swapping components like speaker tags, microphone and ear cushions (sold separately in ASTRO Mod Kits). For serious livestreamers, the MixAmp Pro TR is áre-engineered with all digital components for lag and interference free operation. The included ASTRO Command Center software allows Pros and Livestreamers to tune every input and output parameter of the MixAmp Pro TR to precisely configure it for their specific setup. All TR products are the Official Equipment of Call of Duty: Black Ops 3 and are used by top Call of Duty Pro teams like Optic Gaming and Team Envyus.
