I was wondering if you can attach a sound card to the Astro A50 or if you should. Does the Astro need a sound card? (on the Playstation 4-5)
No doesn't need it. But it's not the best choice for gaming either.
Why isn't this the best choice for gaming?
Since it is a wireless headset and you have one latent, you also have to charge it regularly and the sound quality suffers. But that is my personal feeling. I have the Mmx300 and I'm more than satisfied.
