Our Verdict
Anker Soundcore Liberty Air 2 Pro Truly Wireless
Sony WF-1000XM4 Truly Wireless
The Anker Soundcore Liberty Air 2 Pro Truly Wireless and the Sony WF-1000XM4 Truly Wireless are similarly performing in-ears, and depending on your usage, you may prefer one over the other. The Sony are more comfortable, feel better built, and have longer continuous battery life. Conversely, the Anker have a more neutral default sound profile, which some users may prefer, and their ANC does a better job of blocking out background noise around you.
