Our Verdict
EarFun Air Pro 2 True Wireless 2021
Anker Soundcore Liberty 4 True Wireless
The Anker Soundcore Liberty 4 True Wireless have a lot more features than the EarFun Air Pro 2 True Wireless 2021. The Anker have a companion app with features like an EQ, a virtual soundstage feature to help immerse you in your audio, and they support multi-device pairing. However, the EarFun have a more neutral sound profile, which some users may prefer, and their ANC is able to block out more background sound.
