Anker Soundcore Liberty 5 Pro: Guinness World Record Call Clarity

Certified by Guinness World Records in April 2026 for the highest speech quality score among TWS earbuds, the Anker Soundcore Liberty 5 Pro sets a new benchmark for noise cancelling wireless earbuds. The ANKER Thus™ AI Chip delivers 150× the computing power of the previous generation, processing 384,000+ noise signals per second for whisper-clear voice pickup.

Standout Features That Define the Category

What separates this model from competitors is its 10-sensor array: 8 microphones plus 2 voice pickup units work with the Thus™ AI Chip to isolate speech from chaotic surroundings. Adaptive ANC 4.0 is rated 100% more effective than the Liberty 4 Pro, blocking subway rumble and street noise. Auto Transparency with Voice Detection activates when the wearer speaks.

Technical Specifications — Sound, Battery, and Connectivity

Audio centers on 9.2 mm wool-paper diaphragm drivers tuned for Hi-Fi sound. The soundcore app unlocks HearID 5.0 personalized EQ plus an AI Sound Enhancer that recovers 65% of detail lost in Bluetooth compression. Battery life reaches 6.5 hours per bud with ANC on, and a 5-minute fast charge delivers 4 hours of playback.
