Turning Call Quality into the Main Feature
With the Liberty 5 Pro and Liberty 5 Pro Max, Anker is reframing what premium wireless earbuds are for. Instead of leading with music features or minimalist design, Soundcore is explicitly positioning call performance as the headline. Both models share the same earbud hardware, including 9.2mm drivers, an eight‑microphone array, and two bone‑conduction sensors that focus on voice pickup. Reviews already highlight “top‑notch” voice‑calling performance, and Soundcore says the Liberty 5 Pro has earned a Guinness World Records certification for the highest speech quality score for true wireless earbuds. That recognition, while largely symbolic, signals how aggressively the company is chasing wireless earbuds call clarity as a differentiator against mainstream flagships from better‑known brands. For people who spend more time in meetings and on calls than listening to lossless albums, the Liberty 5 Pro line is being marketed as AI call quality earbuds first, and everything‑else headphones second.
Inside the Thus AI Chip: 150x More Compute for Your Voice
At the center of Soundcore’s strategy is the new in‑house Thus AI chip, built around a Compute‑In‑Memory architecture. According to the company, it delivers up to 150 times more AI processing power than the previous generation, specifically tuned for matrix operations used in noise cancellation and voice enhancement. Instead of simply applying a static DSP filter, the noise cancellation AI chip continuously analyzes input from the eight microphones and bone‑conduction sensors to distinguish the wearer’s voice from traffic, wind, or office chatter in real time. This extra headroom also powers Adaptive ANC 4.0, which samples ambient noise up to 384,000 times per second and adjusts the attenuation curve on the fly. The result, on paper, is stronger ANC than Soundcore’s last generation and competitive suppression against leading flagship rivals, while still prioritizing speech intelligibility when you’re on a call.
Cleaning Up Calls: How AI Separates Speech from Noise
Most wireless earbuds struggle when the world gets loud, because your voice and background noise occupy overlapping frequencies. The Liberty 5 Pro series tackles this with a layered AI pipeline running on the Thus AI chip. First, the microphones and bone‑conduction sensors capture both airborne sound and vibrations from your jaw, giving the system a cleaner reference of your speech. Then, a trained AI model isolates that voice signal, suppressing everything from subway rumbles to open‑plan office chatter. Independent testing under ETSI TS 103 106 conditions has reportedly shown excellent voice clarity and strong noise suppression versus several global flagships. Crucially, much of this processing happens on‑device, so built‑in voice commands and call enhancement don’t depend on sending audio to remote servers. That brings lower latency and better privacy while still delivering wireless earbuds call clarity that aims to sound closer to a dedicated headset than a typical pair of earbuds.
Beyond Calls: Adaptive ANC, Voice Commands and Translation
The same Thus AI chip technology is being used to widen the feature set beyond simple voice calls. Adaptive ANC 4.0 constantly re‑profiles the sound environment—street traffic, subway droning, or office HVAC—and tweaks cancellation strength and frequency focus in real time. HearID personalization further tailors sound to the listener’s hearing profile. On‑device AI enables around 20 built‑in voice commands, letting users change volume, playback, or ANC modes hands‑free and without a persistent internet connection. Both Liberty 5 Pro models also support conversation translation in more than 100 languages, turning the earbuds into a live interpretation tool. On the Max model, translation extends onto the AMOLED case for richer interaction. Together, these features push the earbuds beyond standard media accessories into everyday productivity tools, especially for users who juggle meetings, commuting, and international collaboration and need AI call quality earbuds that adapt on the fly.
Liberty 5 Pro vs. Pro Max: Two Tiers of AI Productivity
While the Liberty 5 Pro and Liberty 5 Pro Max share core audio and call features, their cases create two distinct tiers. The Liberty 5 Pro includes a compact touchscreen that surfaces quick controls—ANC modes, playback, and key settings—without opening the app, keeping the focus on value and portability. CNET notes it as the better buy for most people and labels it an Editors’ Choice pick. The Liberty 5 Pro Max, by contrast, leans into workplace productivity with a larger 1.78‑inch AMOLED display and an integrated microphone in the case. This enables the AI Note‑Taker: double‑tap the case to record a meeting or lecture, then generate transcripts, summaries, speaker labels, and action items. Both models integrate translation and call‑focused AI, but the Max turns the case into a standalone capture device—positioning it as a mobile meeting assistant rather than just a charger.
