After weeks of rigorous testing, I’m ready to share my in-depth review of the soundcore Liberty 4 (A3953 / A3953011 / A3953Z11 / A3953G11) true wireless earbuds. These earbuds promise premium sound, immersive spatial audio, and even heart rate tracking – quite a lot for a single package. Let’s dive in and see if they deliver on their ambitious claims.

The Liberty 4 earbuds boast a compelling array of features. Beyond the advertised ACAA 3.0 acoustic system with dual dynamic drivers, the 360° immersive spatial audio with head tracking is a standout feature. The inclusion of a heart rate sensor, accessible through the soundcore app, adds a unique health-focused element. Comfort is addressed with CloudComfort ear tips in multiple sizes, ensuring a secure and comfortable fit for a variety of ear shapes. The personalized sound feature, tailored to individual hearing profiles, is a nice touch.

The sound quality is impressive. The ACAA 3.0 system truly shines, delivering a rich and detailed soundscape with punchy bass, clear mids, and crisp highs. The spatial audio works remarkably well, creating a truly immersive experience while watching movies or listening to music. The heart rate sensor, while not as accurate as a dedicated fitness tracker, provided reasonably consistent readings during my testing. The battery life is also quite good, easily lasting through a full workday.

However, the noise cancellation, while present, isn’t the most effective I’ve experienced. It noticeably reduces ambient noise, but doesn’t completely eliminate it, especially in loud environments. The touch controls are responsive but can be slightly finicky at times, requiring a bit of getting used to.

Pros:

• Excellent sound quality with detailed and balanced audio.
• Immersive and effective spatial audio.
• Comfortable and secure fit thanks to CloudComfort ear tips.
• Unique heart rate tracking feature.
• Good battery life.

Cons:

• Noise cancellation could be improved.
• Touch controls can be slightly inconsistent.
• Heart rate tracking accuracy isn’t perfect.

Overall, the soundcore Liberty 4 earbuds offer a compelling package of features and performance. The outstanding sound quality and immersive spatial audio make them a joy to use. While the noise cancellation and touch controls could be refined, these minor shortcomings don’t overshadow the positives. If you’re looking for true wireless earbuds with premium audio and a unique heart rate tracking feature, the Liberty 4 is a strong contender. I highly recommend them.
