New for 2023, the Anker Soundcore Liberty 4 NC earbuds carry a lower list price than last year’s Liberty 4 buds and are arguably better. They have improved noise canceling and better sound quality, along with support for the LDAC audio codec for devices that support it. (Many Android smartphones do, and in theory it offers slightly improved sound quality when paired with a music streaming service that offers high-res tracks.) They’re lightweight buds that should fit most ears comfortably with four sizes of ear tips to choose from.
The Liberty 4 NC buds have single custom drivers compared to the Liberty 4’s dynamic dual drivers — and a completely different case design — but I thought they delivered more pleasant sound than the Liberty 4s. Their treble is a little smoother and they feature strong bass performance. They came across as fairly open, with a reasonably wide soundstage. You can tweak the sound profile in the companion app for iOS and Android.
The buds come in several color options and are IPX4 splashproof, so they’re suitable for running and gym use. They feature excellent battery life — up to 10 hours on a single charge at moderate volume levels — and there’s also a transparency mode that lets ambient sound in and sounds pretty natural with only a very faint audible hiss. While the noise canceling is an improvement over the Liberty 4’s and is effective, it falls short of what you get from Bose’s and Sony’s premium ANC earbuds.
Like the Liberty 4, the earbuds have six integrated mics for noise canceling and making calls, and callers said they thought the buds did a pretty good job of reducing background noise, with my voice coming through relatively clearly. They’re an all-around good performing set of buds for the money and they have a strong feature set, including ear-detection sensors and wireless charging.
