Anker has introduced two new wireless headphones that boast unique features. The Soundcore Liberty 4 model can monitor the heart rate, while the new Soundcore Sleep A10 can track sleep.
The Soundcore Liberty 4 are Anker's first "leg" headphones with dual dynamic drivers in each earcup. Thanks to a built-in gyroscope and a spatial audio algorithm for tracking head movements, they promise an immersive listening experience. The company claims that the headphones can last up to 9 hours on a single charge, or 7 hours with ANC (ambient noise cancellation) turned on, and up to 28 hours with the charging case.

In addition to the usual sound functions, the Soundcore Liberty 4 is the first Anker headphone to monitor the heart rate, which is the purpose of the built-in sensor (specifically, it is located in the right earpiece). You can access your data through the Soundcore companion app. The headphones are offered in black and white, and their price is $150 (roughly CZK 3).
The Soundcore Sleep A10 are Anker's first sleep-monitoring headphones, and the company is pitting them against the Bose Sleepbuds II. The app above will display a record of your sleeping habits, which should help you adjust your sleeping conditions.

The headphones promise to block up to 35 dB of noise, which according to the manufacturer is 15 dB more than the best sleep headphones today. Anker claims the headphones are comfortable to wear, even for side sleepers, and they also work as a personal alarm clock. Unlike other brands that are limited to playing audio from specific apps, these headphones can also play any audio via Bluetooth. The Soundcore Sleep A10 are sold (via online trade Anker or Amazon) for 180 euros, or dollars (about 4 and 400 CZK).
