Today, September 30, Anker officially introduced its new Soundcore Liberty 4 TWS headphones, which can be conditionally classified as inexpensive truly wireless headphones – they will be sold for $ 150. It is worth noting that this is the first model in this line that received the “stick” design, plus the manufacturer has implemented a design with dual dynamic drivers in such a compact format. It is thanks to this solution that the new headphones, as the company says, significantly push the boundaries of the sound quality of various content – absolutely all frequencies will be worked out at the highest level.
Of course, for now, you can evaluate the sound quality of this model solely by the characteristics from the press release, so it’s too early to talk about transcendental sound, but the novelty has several bonuses that look cool even without a visual study. For example, Soundcore Liberty 4 has support for full-fledged spatial sound – when the user tilts his head, the headphones will automatically level the sound stage using a gyroscope and various algorithms. This will work both when watching movies and listening to music tracks, although not all users are enthusiastic about this solution.
In addition, these headphones boast a unique feature that competitors in the market do not have – we are talking about a heart rate sensor that will work right in the user’s ear. Headphones communicate with the proprietary Wellness application in order to track the user’s daily health data, or you can track your performance during the workout. A very useful thing in case the user does not have a smart watch, a special bandage tracker or a ring for a similar task (headphones in this regard can be an even more convenient solution, especially in the gym).
The device also works via Bluetooth 5.3 wireless protocol, supports Soundcore HearID proprietary active noise reduction and LDAC, AAC and SBC codecs (aptX is not supported, unfortunately). The new TWS headphones work from a built-in battery for up to 9 hours without recharging in standard mode, when using spatial sound, autonomy drops to 5 hours, and in LDAC mode with noise reduction, the battery lasts for 6 hours. Fast charging in the case in 15 minutes gives the device up to 3 hours of music playback, the case itself can be charged via USB Type-C or wireless charging – the case adds up to 28 hours of autonomy to the gadget.
