Adapt the ASTRO A40 TR headset to any environment by adding an ASTRO A40 Mod Kit. For loud environments such as pro tournaments, one can transform the A40 TR to a closed-back noise-isolating headset with sealed speaker tags, synthetic leather ear cushions and headband and a voice-isolating microphone. The Halo Mod Kit features art taken directly from the game and was developed in conjunction with 343 Industries. All TR products are the Official Equipment of Call of Duty, the leading console esports title globally.
*Please note: A40 TR Mod Kits are only compatible with A40 TR Headsets and not any other headsets.
