The ASTRO A40 TR Headset for Xbox One, PC, and Mac is the premier gaming audio solution for professional gamers, including esports athletes, content creators, streamers, 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. The MixAmp™ Pro TR features Dolby Digital Surround Sound processing and enables lag and interference free delivery of game sound and voice communication to the A40 TR Headset. Its simple controls allow for quick adjustment of game-to-voice balance settings, determining how much game sound and voice chat the user hears. It also allows users to select 1 of 4 different EQ modes optimized for different game genres, as well as providing master volume control. All these features make the ASTRO A40 TR Headset and MixAmp™ Pro TR not only the best pro gaming headset setup, but also the ideal headset for streaming and the ultimate audio solution for all gamers and audiophiles. All TR products are the Official Equipment of Call of Duty, the leading console esports title globally.

Everything you ever hope for

So what can i say? So for the past 2 weeks i've been trying to find a headset that I can mix other audio signals into my game audio/chat audio.. (discord chat audio from mobile phone to game audio) with absolutely no luck at all. How ever i finally decided to try these Astros A40 TR +mixamp pro... was exactly what I was hoping for. I can mix in any audio signal with no buzz/hiss/crackle and STILL be able to use the headset's microphone for in game purposes. Works like a charm, check it out, you wont be disappointed..

Headset is amazing

Overall The best headset I have ever owned, The quality is great and the sound + sound customization is just amazing. The Mixamp is convenient and easy to use. I love my A40 TR+Mixamp and if you're a serious gamer then I recommend these over every other headset.

Fantastic sound but still issues

I purchased this headset after repeat issues of mic failure on cheaper varities of Xbox One headsets.Pros: The sound quality is fantastic, the headset is by far the most comfortable I have encountered (pretty much in line with the wireless Trittons on the old Xbox 360)Cons: The Usb-Micro lead supplied was never a great fit & with excess movement, the headset cuts off due to the connection coming lose. The has got worse with time & now can not touch the Mixamp at all!After 6 months the mic has also stopped working!The leaflet in the box states that you can not take this item back to store and must deal with Astro direct however they are very slow to repond with a 48 hour delay on every question they ask.I am still waiting for my faulty items to be replaced...which is a shame for what got be the ultimate brand for gaming headsets.


Love these headphones when they work, best headphones I have ever owned. Sound is unparalleled, mic when it works is great my friends say.only problem I have found is that my computer will randomly stop using my headphones and mic, even though I have set them to default. Only thing I would ask if for the driver to have more customising like the razer surround, and for the driver to make my computer use my headset without forcing me to close my game to relocate the mic and head set.

Best headset I’ve had ever in my life

I’ve been wanting this head set since 2014 and I was able to finally get it in 2016 when the Tr’s came out and I got them at Pax east for a deal. I’ve owned for 2 years now and it’s the best gaming purchase I’ve ever made. I would recommend getting a mod kit because the ear cups and mic and such is way better and more compfy. This is coming from a 16 year Old and these are awesome I would recommend these if you sit down in front of a desk or close to a tv. Wish they had a A50 Tr that would be awesome. OVERALL: You won’t regret this purchase most comfortable and stylish and customizable headset way worth for 250$!
