The new Astro A40 TR Headset + Mix Amp Pro TR features user customization to adapt to any environment. Transform the A40 TR from an open-back to a closed-back noise cancelling headset by swapping components like speaker tags, microphone and ear cushions (sold separately in Astro Mod Kits). The Mix Amp Pro TR is re-engineered with all digital components for lag-free /interference-free operation. The included Astro Command Center software allows Pros and Live streamers to tune every input/output parameter of the Mix Amp Pro TR for their setup.
