The verdict
These are definitely a contender for some of the best affordable noise canceling earbuds based on performance and value. With an IPX4 rating, long battery life, and good ANC, these are worth a go. You might not want to go for a run with them, but otherwise they're decent.
✓Liked: Price, ANC, Battery life, LDAC, AAC, SBC codecs
✕Could be better: Chunky case, Many EQ presets are too bassy

How we verify ownersWhat a reader who owns the Anker Soundcore Liberty 4 NC reports after living with it. Owner-reported, checked before publishing; ordered photo-verified first, then newest.
Owner reviews are not paid for, not solicited from specific owners, and not rewritten by us: at most we proofread typos, which is shown on the review’s own page and which the author can undo. The commission SoundGuys may earn on this page comes from retail links, never from owner reviews.
