Our Verdict

Astro A40 TR Headset + MixAmp Pro 2019

Razer Kraken Ultimate

The Astro A40 TR Headset + MixAmp Pro 2019 are much better wired gaming headphones than the Razer Kraken Ultimate. The Astro are more comfortable, have better controls that you can tweak on-the-fly, and they have a slightly better build. They have a more consistent frequency response, and their detachable boom microphone has a better overall performance. However, the Razer have an adjustable surround sound feature.
