The Anker soundcore Liberty 5 Pro in Midnight Black is the world's clearest-calling true wireless earbud — certified by Guinness World Records in April 2026 as the holder of the "Highest speech quality score (G-MOS) for TWS earbuds (objective test)", powered by the Anker Thus™ AI Chip — the world's first Neural-Net Compute-in-Memory audio chip — and combining Adaptive ANC 4.0, Whisper-Clear call technology, LDAC Hi-Res Audio, HearID 5.0 personalised sound, Dolby Atmos with head movement tracking, 20 built-in offline voice commands and a 0.96-inch smart display charging case in a 5.5-gram body that is 38% smaller than the previous generation. The Guinness World Record certification is the external independent validation of a call quality architecture that sets the Liberty 5 Pro apart from every competing true wireless earbud available at any price point — the G-MOS (Goldstandard Mean Opinion Score) is an objective speech quality measurement protocol that removes the subjectivity of listener panels by using a calibrated acoustic model to score the intelligibility of transmitted voice, and the Liberty 5 Pro achieved the highest score of any TWS earbud tested under this protocol, a result that the Verge described as "the best in-call noise cancelling from any earbuds." The architecture behind this record is the Whisper-Clear call system: 8 MEMS microphones, 2 bone-conduction Vibration Pickup Units that read the mechanical vibration of the user's skull rather than airborne sound — making the voice signal available independently of ambient noise — and an AI Large Model running on the Anker Thus™ AI Chip that fuses the microphone array and bone conduction data streams together into a single isolated voice signal accurate enough to transmit speech clearly in environments exceeding 100 dB.

The Anker Thus™ AI Chip — the world's first Neural-Net Compute-in-Memory audio chip for consumer earbuds — processes audio intelligence at 150 times the computing power of conventional earbud chips by implementing the neural network computation directly inside the memory architecture rather than routing data between a processor and a separate memory store, eliminating the latency and power overhead that conventional chip designs incur when running real-time AI audio processing. The Adaptive ANC 4.0 system uses 8 dedicated noise-sensing microphones together with the Thus™ AI chip to process more than 384,000 noise signals per second — 100% more effective at noise cancellation depth than the Liberty 4 Pro — continuously adapting to the noise profile of the current environment whether that is a subway car, an open-plan office, a busy street or a coffee shop, delivering instant silence without the audio artefacts and pressure sensation that early ANC implementations produced. The 9.2mm Wool-Paper Diaphragm driver delivers the acoustic performance that the Liberty 5 Pro's sound engineering is built around — wool-paper composite diaphragm material combines the rigidity and impulse response of a rigid cone with the internal damping of a soft dome, producing the high-frequency detail and bass extension simultaneously that conventional single-material drivers trade off against each other. LDAC support at the codec level enables lossless Hi-Res Audio wireless transmission from compatible LDAC Android devices at up to 990kbps — approximately three times the data rate of standard SBC and AAC — delivering the full resolution of Hi-Res Audio files without the compression artefacts that lower-bitrate Bluetooth audio introduces. HearID 5.0 tests the user's individual hearing sensitivity profile across frequencies and generates a personalised EQ curve matched to their specific hearing, with the AI Sound Enhancement layer restoring up to 65% of the audio detail lost in standard Bluetooth compression in real time during playback. Dolby Atmos with head movement tracking uses the Liberty 5 Pro's internal motion sensors to anchor the spatial audio soundfield to the room rather than the head — so the soundstage moves naturally as the listener turns their head, creating the immersive three-dimensional listening experience that Dolby Atmos was originally designed to deliver in cinema environments. The 20 built-in offline voice commands — skip, volume, call control, ANC mode and more — execute without internet connectivity through on-device processing on the Thus™ AI Chip, with a response time three times faster than standard voice control implementations, in English, German, Japanese and Chinese. The 0.96-inch smart display charging case provides direct control of ANC mode, EQ presets, Dolby Atmos, Bluetooth connections and battery status from the case touchscreen without opening the soundcore app. Battery delivers 6.5 hours per charge with ANC on and 28 hours total with the case, with 5-minute fast charging providing 4 hours of playback — Bluetooth 6.1 earbuds connect to up to 3 devices simultaneously. IP55 dust and water resistance. 2-year warranty.
