Soundcore Liberty 4 NC Wireless Earbuds - Adaptive ANC and Hi-Res

Our review of the Soundcore Liberty 4 NC finds these wireless earbuds best suited for commuters, frequent travelers and music lovers who want strong noise cancellation without sacrificing audio detail. The single biggest reason to buy is the ANC system, which pairs a high-sensitivity in-ear sensor with an isolation chamber to cut ambient sound dramatically, giving a noticeably quieter listening environment for work, flights, or busy streets. Sound lovers will also appreciate the Hi-Res capable 11mm drivers and LDAC support that deliver clearer, more detailed playback than typical Bluetooth earbuds.

Key Features

• Up to 98.5% noise reduction: The in-ear sound sensor and noise isolation chamber work together to remove a large portion of background noise for more focused listening.
• Adaptive ANC 2.0: Real-time adjustments to your ear canals and surrounding environment help preserve quiet across changing noise conditions.
• Hi-Res audio with LDAC: 11mm custom-tuned drivers and LDAC transmission provide more data throughput and clearer, more detailed sound than standard Bluetooth codecs.
• Personalized sound: HearID 2.0 plus an adjustable EQ and 22 presets let listeners sculpt a preferred sound signature without equipment changes.
• Long battery life: Up to 10 hours per charge in normal mode and as much as 50 hours with the case for extended use between charges.
• Clear calls with AI: Six beamforming microphones and an AI algorithm boost voice clarity while reducing background noise for phone conversations.

Who It's For

The Liberty 4 NC are ideal for daily commuters and travelers who need effective noise cancellation and multi-day battery life, and for audiophiles who want Hi-Res capable wireless sound without bulky equipment. They also suit users who switch between devices often thanks to Bluetooth 5.3 and multipoint connection.

These earbuds are less appropriate for listeners who need studio-grade reference neutrality or for those who prefer very compact true wireless buds with minimal ear sealing; the design relies on an isolation chamber and a fit that may feel more pronounced than open-fit alternatives.
