Today, September 30, Anker has officially unveiled its new Soundcore Liberty 4 TWS earphones, which can be tentatively classified as cheap truly wireless earbuds – they’ll retail for $150. This is the first model in this line to receive a “rod” design, and the manufacturer has implemented a dual dynamic driver design in such a compact form. Thanks to this decision, the new headphones, as the company claims, significantly push the boundaries of the sound quality of various content – absolutely all frequencies will be processed at the highest level.

Of course, the sound quality of this model so far can only be judged by the specs in the press release, so it’s too early to talk about sound, but the new product has several bonuses that look great even without visuals. peak. For example, Soundcore Liberty 4 supports full spatial audio – when the user tilts their head, the headphones automatically align the soundstage using a gyroscope and various algorithms. This should work for both watching movies and listening to music tracks, although not all users are happy with this decision.

In addition, these headphones have a unique feature that competitors in the market do not have – we are talking about a heart rate sensor that will only work in the user’s ear. The headphones connect to the company’s Wellness app to keep track of the user’s daily health data, or you can track your performance during a workout. A very useful thing if the user does not have a smartwatch, a special armband or a ring for a similar task (for that matter, headphones can be an even more convenient solution, especially in the gym).

The device also works with the Bluetooth 5.3 wireless protocol, supports proprietary active noise cancellation Soundcore HearID and LDAC, AAC and SBC codecs (aptX support is unfortunately not available). The new TWS headphones work from the built-in battery for up to 9 hours without recharging in standard mode, the autonomy is reduced to 5 hours when using spatial audio, and the battery lasts 6 hours in LDAC mode with noise reduction. Quick charge in the case in 15 minutes gives the device up to 3 hours of music playback, the case itself can be charged using USB Type-C or wireless charging – the case gives the gadget up to 28 hours of autonomy.
