The Astro A40 headset is impressive for wired gaming. These headphones should be comfortable enough for long gaming sessions, and their wired connection means you encounter very low audio latency.

    Comfortable and sturdy design., Great microphone performance., MixAmp allows you to mix game and chat audio.

  • -

    Poor noise isolation, by design.

Astro Gaming's A40 TR headset with MixAmp Pro TR is a high-quality wired gaming headset/amp combination that provides a very comfortable fit and excellent audio for a premium price.

  • +

    Excellent sound quality., Light, sturdy design feels premium., Plenty of audio customization options through the Astro Command app.

  • -

    Expensive for a wired-only headset., PS4 Slim users need an HDMI splitter.

Great for gaming. The A40 are comfortable for long gaming sessions, have a great sounding microphone, and their sound quality is also good. Their wired connection means you won’t have any delay when playing games, which is great but may not be as convenient as the wireless design of the Astro A50.

  • +

    Comfortable and sturdy design., Good audio reproduction with EQ and presets., Great microphone.

  • -

    Bulky design., Poor noise isolation, by design., Sound delivery varies across users. Sensitive to glasses and fit.

I like them a lot. There is only one problem and that’s I wish they had a shorter cord. Or if they could have like two cords that are for your headphones to controller and one was long and the other one is short. But other then that they are really comfortable and the sound is really good.

The mix-amp is convenient and functions well. I can finally hear certain details from my gameplay that I had trouble hearing with other headsets. They are comfortable to wear for hours and are overall sturdy. The cord from the mix-amp to headset is of sufficient length(6ft I believe).

So what I have read reading through most of the reviews, people don't actually buy the product. They are just saying that it's a good headset just because of the price. I'm not saying it's not a good headset, but people should maybe BUY the product before leaving a review for it.

Really only con is the mic, and that I had issues with getting mine working at first because idk why but theres a mic on the mute button thing and I didn't realize you could switch between that mic and the mic on the actual headset so I had thought there was a defect

    Conformtable Good audio

    The mic isnt the best, but it gets the job done.

The Astro A40 TR gaming headset is "if it ain't broke, don't fix it" incarnate, and there's a lot about the device that simply ain't broke. Comfortable and able to wear for hours. Only downside is there is no volume adjustment it and if you want one you have to by the mix amp

This headset is one of the most comfortable, best sounding headsets I have had! The lows and highs are clear and voices come in loud and easy to hear. I do have the Mixamp Pro as well which is awesome itself. I highly recommend the combination of the A40's and the Mixamp Pro!

Headset build quality is great and I love the noise cancelling set! I have had TRITTON, Turtle beach, steelseries, and an XBOX brand and these are by far my favorite. The M80 makes it easy to customize chat and game quickly. Its also nice how most parts are replaceable if needed.

Just to clarify this is the Astro A40 PC. It is designed for PC and notebook gaming, and while it is made to work with a computer it WILL work with XBOX and Playstation consoles.... that is if you buy a separate mixamp. Just a heads up.
