Our Verdict
Anker Soundcore Liberty 4 NC Truly Wireless
Anker Soundcore P40i
The Anker Soundcore Liberty 4 NC Truly Wireless and Anker Soundcore P40i perform similarly with mostly minor differences. The Liberty 4 NC support LDAC for high-quality audio. Meanwhile, the P40i have significantly lower latency when you use them in 'Game Mode.' The P40i also have an IPX5 rating, which certifies better protection against water exposure than the IPX4 rating found on the Liberty 4 NC buds. Otherwise, they both have very similar app functionality.
