Our Verdict
Anker Soundcore Liberty 4 NC Truly Wireless
OnePlus Buds 3
The Anker Soundcore Liberty 4 NC Truly Wireless and the OnePlus Buds 3 are found in the same wallet-friendly price bracket. In some ways, they have a similar performance. Both headphones have comfortable and well-built designs, and sound profile customization options in their respective companion apps. That said, the Anker have a better overall noise isolation performance and longer continuous battery life, while the OnePlus' integrated mic can capture your voice more clearly, even in noisy environments.
