[Review] Anker’s New AeroClip 2 Just Made Open-Ear Calls Guinness World Record Clear

Open-ear earbuds have always carried a quiet, unspoken compromise. You get situational awareness and all-day comfort, but phone calls sound like you are shouting from inside a washing machine. Anker’s new soundcore AeroClip 2 aims to bury that trade-off for good, and after spending time with a Burgundy Red review unit, the difference is not just noticeable. It is the entire point of the product.

The core problem with every open-ear design is physics. As the earbud never seals your ear canal, your voice and the surrounding noise reach the microphones through the same medium, air, arriving as one mixed signal. Filtering that mess has been the industry’s only answer, and filtering falls apart the moment you step onto a busy street or into an MRT carriage.

Anker’s solution is almost counterintuitive: stop relying on air alone.

Two voice pickup units read vibrations directly from your vocal cords, a signal that is physically coupled to your voice and completely independent of airborne noise. The company’s THUS AI chip then cross-references that vibration stream against four MEMS microphones in real time, effectively giving the earbuds two separate information sources where competitors have only one.

That chip is not an unproven experiment. The same THUS platform powered the Anker soundcore Liberty 5 Pro, which earned Guinness World Records certification in April 2026 for the highest objectively measured speech quality score in TWS earbud history.

The AeroClip 2 brings that silicon to an open-ear form factor, and in August 2026 it earned its own Guinness certification for the highest speech quality score among open-ear clip-on earbuds. The technology delivers 4.6 GFLOPS of on-device processing, roughly 150 times the AI computing power of the previous generation, all while staying within the power budget of a wearable.

In practice, I wore the AeroClip 2 through my workout sessions and found the freedom genuinely liberating.

The magnet snaps each earbud into the charging case naturally, and the L and R indicators are immediately clear because the magnet simply will not engage if you insert the wrong side. That small design decision speaks to how much thought Anker put into the everyday experience.

During exercises, the 6.2g per earbud weight and the GoldenFit C-bridge, developed from over 2,000 ear scans, kept everything secure without any readjustment. I forgot I was wearing them, which is both a compliment and a minor hazard when you go to pull off a shirt.

Sound quality is where open-ear designs have historically stumbled, and the AeroClip 2 makes a respectable case for itself with 12mm dual-magnet drivers and LDAC hi-res support.

Vocals come through clearly, instruments have reasonable separation, and there is enough bass to give music weight without pretending to compete with sealed in-ears. The physics of an open design place a hard ceiling on sub-bass, and anyone expecting nightclub-level thump will be disappointed.

Although I did not use it, the accompanying soundcore app includes HearID 5.0 personalised EQ to tailor the sound, and real-time AI translation across more than 100 languages, adding a useful layer for travel and work.

Battery life sits at eight hours per charge, extending to 32 hours with the case, and a quick ten-minute top-up provides another four hours. IP57 dust and water resistance means sweat and rain are not a concern.

The AeroClip 2 is available in Singapore at S$249, with colour options including Burgundy Red, Midnight Black, and several others.
