The ASTRO A40 TR is the premier gaming headset for professional gamers, including esports athletes, content creators, steamers, and game developers. It was developed with esports athletes to meet their rigorous standards for audio fidelity, comfort, and durability. Able to adapt to any environment, the A40 TR arrives as an open-back headset featuring a swappable precision mic and customizable speaker tags. For loud environments such as pro tournaments, one can transform the A40 TR to a closed-back noise-isolating headset by adding a Mod Kit (sold separately) which features sealed speaker tags, synthetic leather ear cushions, and a voice-isolating microphone. For VR gamers, the A40 TR will fit perfectly over the HTC Vive, Oculus, or PS VR and deliver an immersive audio experience. For Xbox One and PS4 users, the A40 TR headset can plug into the 3.5mm jack directly on the controller for stereo sound and voice chat. All TR products are the Official Equipment of Call of Duty, the leading console esports title globally.
