My favorite thing about the Arctis Nova 3 is their fit: They are the most comfortable of any gaming headset I've tested. They're super lightweight, which makes them great for long gaming sessions and larger heads like mine, and the ear cups are a light, squishy mesh that's breathable without sacrificing too much in sound isolation. Despite the super lightweight build, the battery life doesn't disappoint, with these cans lasting around 30 hours on a single charge.
