'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
They also introduce what the company describes as 360-degree immersive spatial audio: This feature allows sound to surround you from all directions and follows your head movement via dynamic head tracking.
Spatial audio customizes the sound you hear in your earbuds depending on the content you're consuming, so for example there are different modes for movies and music.
The spatial audio feature will be offered in addition to the traditional Adaptive Noise Canceling (ANC) and transparency option (which lets in all the sound around you).
Lastly, the earbuds have HearID ANC, which automatically adjusts the noise cancellation for different noise levels around you. You can also use the HearID technology to customize EQ settings to your own sound preferences for personalized sound.
The battery life on the Liberty 4 earbuds provides up to 9 hours of playtime and 28 hours with the charging case. The case can be recharged with a USB-C cable or a wireless charger. You can get up to 3 hours of listening from a 15-minute charge.
Heart rate tracking
These earbuds are Soundcore's first to include heart rate tracking. Thanks to incorporated sensors, with the earbuds in your ears, you can track your heart rate in the Soundcore app.
