Our Verdict
Anker Soundcore Liberty 3 Pro Truly Wireless
Anker Soundcore Space A40 Truly Wireless
The Anker Soundcore Space A40 Truly Wireless are slightly better in-ears than the Anker Soundcore Liberty 3 Pro Truly Wireless. While both headphones are similarly comfortable and well-built, the Space A40 have a significantly better full range noise isolation performance, a longer-lasting continuous battery life, and one more additional charge in the case. However, the Liberty 3 Pro have a more stable in-ear fit.
