Audio brand Soundcore has revealed among them are the Liberty 4 earbuds that can track your heart rate. The heart rate sensor is in the right earbud, so you’ll need to wear it to use the feature. When it measures your blood oxygen level, the earbud emits a red light. Soundcore hasn’t disclosed the waterproof rating, which is strange given the heart-rate tracking capabilities are closely tied to exercise.
According to Soundcore, an algorithm can tune spatial audio depending on whether you’re watching a movie or listening to music. The earbuds also offer dynamic head tracking. Soundcore uses a gyroscope to ensure you are always surrounded by sound. In addition, Liberty 4 offers adaptive noise cancellation (which automatically adjusts noise cancellation levels based on ambient noise) and personalized sound.
You get up to nine hours of use on a single charge, claims and a total of 28 hours before you need to charge the charging case battery. Those numbers drop to five and 15 hours with surround sound on, and seven and 24 hours with ANC enabled. However, according to Soundcore, you can use the device for up to three hours after a 15-minute charge.
There’s also so you can pair Liberty 4 to your computer and phone simultaneously via Bluetooth. The $150 earbuds come in white or black. You can now and other traders in October.
Soundcore has also introduced new sleep earphones. It says the Sleep A10 buds can block up to 35dB of noise thanks to a four-point noise-masking system.
Unlike those that only allow you to hear sleep sounds from a specific app, Sleep A10 lets you play any audio over Bluetooth. Soundcore says its earbuds have dynamic drivers designed to deliver low-frequency noise that induces sleep. Crucially, the earbuds appear to be comfortable for people who sleep on their side. They have ear flaps and double-sealed ear tips to keep them snug in your ears at night.
Other features include sleep monitoring and a personal alarm clock. Anker claims the buds have up to 10 hours of battery life, so they should be able to wake you up and lull you to sleep. The Sleep A10 buds, which are $69 less than Bose’s Sleepbuds 2, are available for $180.
