I am a gamer that has used Astro’s for many years going back to them first hitting the scene. I’m currently using a set of Astro A40’s TR with my PC. I am looking to continue using the mix amp (at least I think so) but buy a new pair of headphones to go with it. I mainly play FPS games and occasionally listening to music. The research I have done has pointed me in the direction of the Sennheiser 6 series of headphones but wanted the opinions of this community.
