Soundcore has announced an upgrade to Adaptive ANC 2.0 in its latest Liberty-series wireless earbuds. The 4 NCs are thus rated to actively cancel up to 98.5% of all ambient noise, while delivering "crisp sound" with enhanced detail thanks to specs such as LDAC codec support. They are available in a range of colors for just under US$100 for a limited time.

Anker's dedicated audio brand Soundcore has doubled down on the reputation for advanced wireless technology it seeks to cultivate for its Liberty-series earbuds in their latest 4 NC generation. They boast AANC 2.0 as well as "custom" 11mm drivers, the former of which seems to be an in-house take on adaptive active noise cancellation rather than something similar from platform-makers such as Qualcomm.

Either way, the technology is rated to filter ambient sounds based on changes to their environment (the user's ear included) from moment to moment. As a result, Soundcore states that the Liberty 4 NCs have been SGS-certified "for noise reduction in the deepest frequency band" (or "by up to 98.5%").

Similarly, the 4 NCs also bear official IPX4 and Hi-Res Wireless ratings for water-resistance and audio quality over their Bluetooth 5.3 connection respectively. They also support the LDAC codec, albeit when paired to an Android device only. Soundcore estimates that they and their new, wireless charging pad-compatible case might last up to 50 hours, although AANC 2.0 might need to be left off for maximum battery life.

The 4 NCs also come in colors besides black and white: navy, icy blue or warm pink. They have been priced at US$99 on their release to or Amazon US, with an extra US$20 off on either website until July 11, 2023.
