Anker’s Soundcore audio brand has released a new audio product. The new earbuds are called Liberty 4, which offers a heart rate feature. This heart rate feature is active on the right side. When the earbuds measure the blood oxygen level, they will emit red light. Unfortunately, the Soundcore hasn’t a waterproof certification.
Soundcore features spatial audio while the user is watching a movie or listening to music. The earbuds use a gyroscope to ensure sound always surrounds you. The Liberty 4 has adaptive noise cancelling and a personalized sound.
The Soundcore Liberty 4 can be operated up to nine hours of use on a single charge, and the earbuds can support up to 28 hours in total through the case’s battery. When users use the spatial audio feature, the operating time will reduce to 15 hours and seven and 24 hours when ANC is enabled.
The Liberty 4 has Bluetooth 5.0, which can be connected to a computer and phone at the same time. The earbuds cost $150 and come in two colour options – black and white. The Liberty 4 will be available on Soundcore and other retailers in October.
Soundcore claims the earbuds can block out up to 35dB of noise thanks to a four-point noise masking system. Unlike Bose Sleepbuds 2, which only allows users to listen to sleep sounds from a specific app, and user can play any audio through Sleep A10 via Bluetooth. The company said the earbuds deliver low-frequency sound that induces sleep. This feature can create a comfortable using for folks who sleep on their side.
The Soundcore Liberty 4 offers sleep monitoring and a personal alarm clock. Anker claims the buds can use sleep monitoring for up to 10 hours. The Sleep A10 buds, which cost $69 less than Bose’s Sleepbuds 2, are available from Soundcore’s website for $180.
