Our Verdict
EarFun Air Pro True Wireless
Razer Hammerhead True Wireless 2021
The EarFun Air Pro True Wireless are better in-ears than the Razer Hammerhead True Wireless 2021. The EarFun are more comfortable, have a more neutral default sound profile, and their ANC offers a significantly better noise isolation performance. They also have a better battery performance. However, the Razer have customizable RGB lighting, a companion app with a graphic EQ and presets to help you adjust their sound to your liking and a 'Gaming Mode' to help lower latency.
