The app itself is simple and clear to traverse, as well as responsive. The wear sensor feature works, though I’ve noticed it doesn’t resume as often after it pauses. To enable LDAC mode on your earbuds and establish a connection with a compatible LDAC-supported device, please follow these steps: Anker claims 10 hours per charge and 50 hours with the case, though that’s not the whole picture. The headline figure refers to listening without ANC. With ANC it falls to 8 hours (40 overall), and with LDAC and ANC Anker says it’s 5 hours (25 in total). From the tests I carried out, the Anker Soundcore Liberty 4 NC falls short.
There are plenty more to go around, though, including an earbuds finder, a latency reducer for gaming, multi-point audio to connect to two devices at once, and LDAC high-resolution streaming for supported Android phones (though you can’t use LDAC and multipoint pairing together). The two-setting Transparency Mode was much more useful. Full Transparency increased environmental awareness, while Vocal Mode emphasized vocals to hear and communicate clearly. I felt secure monitoring traffic and sharing conversations with the missus during strolls. Soundcore by Anker Liberty 4 NC: Verdict Within the comprehensive app, more customisation is available with a personalised function (HearID), default EQ (Soundcore Signature), Custom EQ (where you create your own) and 3D Surround Sound that opens up and widens the soundstage. I find this one reduces the impact of bass and makes music thinner. According to Soundcore, the brand behind the Liberty 4 NC, these are its best noise-cancelling true wireless with support for Adaptive ANC that claims to reduce noise by up to 98.5%.The Anker Soundcore app (available for Android and iOS) is among my favorites because of its sleek design and extensive feature set. It shows battery life readouts for each earpiece and the case at the top. Below this, the Ambient Sound section lets you switch between Noise Cancellation, Transparency, and Normal modes. Clear all the pairing records on your phone and re-pair your earbuds. Turn the volume down one notch on your phone. Then turn up the volume of both your phone and earbuds with the music/video to the maximum. The low frequencies never hog proceedings. A listen to DMX’s X Gon’ Give It To Ya reflects that balance, the bass described in detailed and varied terms from the small drumbeats to the bigger, boomier beats that follow. There’s good weight and decent depth provided, though this is an area where the EarFun boasts more muscle. Phone call quality has been muddled. Clarity can be muffled, the other person struggled to hear me in noisy places but when it is quiet, the Liberty 4 NC works fine. The quality here is average for a true wireless, though as the review was published, there was an update to improve call performance. I’ll try it out again and will revise the review if my opinion changes. Sound Quality Listening to a Spotify stream at 50% volume for an hour saw the Anker Liberty 4 NC fall to 80%. That indicates 5 hours with ANC on. In LDAC mode it was between 60 – 70%, which is about 3-4 hours before another charge is needed.
Please note that this doesn't necessarily mean there is an issue with the earbuds but may have something to do with the connected device and environment. Bluetooth signals may be influenced by obstructions, such as walls, pillars, home appliances, Wi-Fi, and more. To ensure a stable connection, we recommend avoiding such obstructions. For budget in-ears, the Liberty 4 NC are notably flashy. They fall short of Vegas-strip looks, but their variety of colorways and touches like the case’s lighted front button and interior lighting set above the buds give a futuristic vibe.
Frequently asked questions
The case’s matte exterior feels well-built and good in your hands, reminiscent of the egg-like case you’ll get with Google’s Pixel Buds Pro—one of many competitors that cost double or more at full price. As with the Space A40, I was delighted to find the case is Qi-charging compatible, something plenty of pricier buds skip. When the battery of the charging case is lower than 60%, the light in the middle of the charging case will turn white for 5 seconds and then go out. If you need to use an audio and video app on the computer and you cannot set the input and output on the app, please open the computer audio settings and choose the correct settings: When resetting the earbuds, make sure the earbuds are well connected with the charging case, or it may cause the reset to fail. When you place left and right earbuds in the charging case, there will be white LED indicators which confirms the earbuds are properly connected with the charging case. Press and hold the charging case button for 10 seconds until the LED indicators in the charging case flash white rapidly three times. This confirms that the reset is successful.
