Anker Soundcore Liberty 4 Pro NC TWS Earbuds

Soundcore Liberty 4 Pro NC — The Case Has a Screen. And It Changes Everything.

Most earbuds put all the smarts in your phone app. The Soundcore Liberty 4 Pro NC puts some of them right on the charging case — with a built-in display that shows battery percentage, ANC mode, and lets you control noise cancellation through 10 levels without touching your phone. It’s a design detail that makes the Liberty 4 Pro feel genuinely premium and practical in ways competitors simply haven’t thought of yet.

📺 Charging Case with Display — Control Without Your Phone

Open the Liberty 4 Pro’s translucent lid and you’re greeted by a compact display on the case itself, showing the battery percentage of both earbuds and the case. More usefully, a physical slider button on the case lets you cycle through 10 levels of ANC strength — without opening an app, without touching the earbuds. Heading into a loud train? Crank the ANC from the case. Stepping outside? Dial it back. Immediate, intuitive, elegant.

🔇 Adaptive ANC — 3 Recalibrations per Second

The Liberty 4 Pro’s ANC algorithm recalibrates three times per second — continuously monitoring and adjusting noise cancellation as your environment changes. In a peer-tested comparison, it reduced noise in the 600-700Hz range (where voices and mid-frequency noise live) by 12.2dB more than with the algorithm off. Across real-world environments — flights, buses, cafes, offices — the ANC is consistently effective and noticeably stronger than the standard Liberty 4 NC.

🎵 11mm Drivers + LDAC — Hi-Res Wireless

The Liberty 4 Pro carries Hi-Res Audio Wireless certification with full LDAC codec support — streaming at up to 990kbps, 3× the data of standard SBC. On compatible Android phones, the jump in audio detail is real — more spatial depth, cleaner treble, and a more coherent stereo image. Pair it with the 8-band custom EQ and HearID 2.0 hearing personalization, and the Liberty 4 Pro is the most precisely tunable earbuds in its price range.

⚡ 2× Faster Charging + Wireless Case Charging

The Liberty 4 Pro charges twice as fast as the Liberty 4 NC — a 10-minute charge delivers 4 hours of playback. The case charges via USB-C or via Qi wireless charging pad — set it down on your phone charger overnight and wake up fully powered. Total battery: 8 hours per earbud with ANC on, up to 40 hours with the case.
