Our Verdict

Sennheiser HD 490 PRO

Sony INZONE H6 Air

The Sennheiser HD 490 PRO and Sony INZONE H6 Air are similar open-back headphones with a balanced sound. Both are usable for gaming due to solid stereo matching and a decent helping of bass, considering they're open-backs. However, the Sony come with a detachable boom mic and a USB-C adapter, which may be preferable for gamers without a dedicated microphone. Still, it's worth noting that the Sennheiser come with a second set of earpads, which can be beneficial if you use the headphones for studio work in addition to gaming.
