Soundcore by Anker Liberty 4 NC Wireless Earbuds

Why it's worth it

The Liberty 4 NC blocks a claimed 98.5% of ambient noise using an in-ear sensor that adapts to your ear canal, and it supports LDAC for hi-res streaming. You get 10 ANC modes, 22 EQ presets, and multipoint pairing to a phone and laptop at once.

This is the pair that gets the fundamentals right without asking you to compromise. RTINGS measured the Liberty 4 NC blocking 98.5% of ambient noise in standardized testing, a figure that beats some headphones costing considerably more. Tom's Guide named it Best Value ANC Earbuds for 2025, pointing to the 10 customizable ANC modes and 28 hours of total battery with ANC running. Those aren't marketing numbers pulled from a box.

The adaptive system is the part you'll notice day to day. Adaptive ANC 2.0 checks the seal in your ear and recalculates in real time, which matters because seal is most of the battle. TechRadar found that a proper ear canal fit adds 12 to 15 dB of attenuation on its own, often more than the ANC circuitry contributes. If your tips shift when you chew or talk, the Liberty 4 NC compensates instead of leaking bass and letting the rumble back in.

What to know

• –Fit isn't universal. Some owners find the buds don't seat snugly, and since seal drives most of the noise blocking, a loose fit…
• –Long-term reliability is the real question mark
