Most ANC earbuds use a fixed noise-cancelling profile that works well only in specific environments. Soundcore Liberty 4 NC takes a different approach: Adaptive ANC 2.0 continuously measures your ear canal fit and ambient noise levels, then adjusts the cancellation algorithm in real time. The result is up to 98.5% noise reduction that actually holds across different settings — office, commute, cafe, or flight.

Audio quality is backed by Hi-Res Wireless certification and LDAC codec support, which streams audio at up to three times the bandwidth of standard SBC Bluetooth. The 11mm drivers handle the full frequency range with clarity, and HearID 2.0 creates a personalized EQ curve based on a listening test tailored to your hearing. Six microphones with AI processing handle calls with the same clarity standard as the music performance. Bluetooth 5.3 with multipoint connects two devices simultaneously.

IPX4 water resistance covers sweat and rain. Backed by an 18-month Soundcore warranty through Anker Philippines, official authorized retailer.
