1 / 10An audacious attempt from Anker.
At 4.4, its noise isolation / ANC beats 34% of wireless earbuds we've measured.
Measured on 133 of the 271 we've cataloged.
above average for wireless earbuds — based on 243 of 271 we've cataloged.
above average for wireless earbuds — based on 245 of 271 we've cataloged.
IPX4 is the most common — on 33% of the 244 wireless earbuds we've cataloged (of 271).
As the former flagship product in Anker's extensive true wireless earbud lineup, the Liberty 3 Pro attempts to pack in every feature imaginable at a price that undercuts the top competition. There's a ton of customization flexibility, but the earbuds fall short when it comes to raw performance. Still, these earbuds sure are a ton of fun to use.
