Anker just made its biggest move yet in the audio space. The Soundcore Liberty 5 Pro and Liberty 5 Pro Max have officially launched – and the headline feature isn’t the noise cancellation or the touchscreen case. It’s a chip Anker built entirely from scratch, called THUS, which forms the brains of the earbuds – understanding, adapting, and tuning.
The THUS Chip – What It Actually Does
The THUS chip uses a “compute-in-memory” design, which means the AI model and the processor live in the same place. That’s a departure from how most chips work. Normally data has to shuttle back and forth between memory and the processor on every cycle. By removing that back-and-forth, the chip uses far less power and takes up far less physical space, which matters a lot when you’re fitting it inside an earbud.
Anker claims the THUS chip delivers 150 times more AI computing power compared to earlier Soundcore models. In April 2026, the Soundcore Liberty 5 Pro received a Guinness World Records title for achieving the highest G-MOS speech-quality rating ever recorded for true wireless earbuds during objective evaluation tests. We can expect the result in real life to have cleaner voice isolation in loud environments like MRT stations, hawker centres, and busy offices.
Soundcore Liberty 5 Pro & Soundcore Liberty 5 Pro Max
Both the Liberty 5 Pro and Liberty 5 Pro Max use a 10-sensor array made up of eight MEMS microphones and two bone-conduction sensors, all powered by a large neural network running locally on the THUS chip. The MEMS microphones capture the surrounding soundscape, while the bone-conduction sensors pick up vibrations from the speaker’s skull that are directly linked to the user’s voice and unaffected by ambient airborne noise. By analyzing both inputs together in real time, the THUS™ chip delivers significantly more accurate voice isolation than systems that rely solely on microphones.
Adaptive ANC 4.0 continuously analyzes surrounding and in-ear noise in real time, automatically adjusting its cancellation strength to suit different environments and sound frequencies. By dynamically balancing noise reduction and ear pressure, it provides a more comfortable long-listening experience while delivering up to twice the ANC performance of the Liberty 4 Pro.
HearID 5.0 creates a customized EQ based on the user’s hearing profile through an in-app assessment, while AI Sound Enhancement helps recover audio detail commonly lost during Bluetooth compression, restoring up to 65% of degraded sound information.Both models support multipoint pairing for up to three devices, along with Apple Find My, Google Fast Pair, Bluetooth 6.1, and IP55-rated dust and water protection. Battery life is estimated at 6.5 hours with ANC enabled, extending to 28 hours with the charging case.
The Liberty Pro Max carries all of the above and adds a neat AI feature that makes it genuinely different. The charging case doubles as a standalone voice recorder with eight built-in microphones – useful for students, journalists, or anyone who regularly captures meetings or lectures. But it is not just a regular voice recorder, it is an AI note taker. It can record sessions without a connected phone, then generates transcripts, speaker identification, and action items via the Soundcore app. If you used Granola before, it’s probably something similar.
Where to Buy
The Soundcore Liberty 5 Pro Series is expected to launch on 6 June 2026 in Singapore. Keep an eye on Shopee, Lazada, and soundcore.com for local pricing and any launch promotions.
