Turtle Beach Atlas Air Wireless Open Back PC Gaming Headset.
The Turtle Beach Atlas Air is an open-back headset I liked for its wide, detailed soundstage—footsteps and direction cues came through clearly in FPS testing. The tradeoff is you get basically no noise isolation, and I also ran into random connectivity cut-outs on one gaming PC setup.
Pros
+Wide, detailed soundstage (great for FPS positioning)
+Clear footsteps and strong spatial audio performance
+Swarm 2 software with robust EQ presets and customization
