Soundcore Anker Liberty 4 Noise Cancelling Earbuds

Active Noise Cancelling

The Anker Soundcore Liberty 4 also uses the created sound profile for active noise-cancelling. The noise-cancelling can act independently and, for example, increases the noise filtering in noisy environments (adaptive). Inside the wireless in-ears are microphones that capture environmental noise. At the same time, they send sound waves in opposite directions to the ears. The sound waves of the noises and those of the headphones overlap, and silence is created. This works well, and the adaptive anti-noise is effective. In particular, low, constant noises are quieter.
On the other hand, noise-cancelling is powerless against voices, but in the best case, the music covers up the chattering fellow travellers. If users want to pay attention to their surroundings, they switch to transparency mode. This allows noises to reach the ears almost unchecked. This function is beneficial if you want to listen to training announcements. In addition, the transparency mode offers two options: On the one hand, the earpieces let everything through, and on the other, only voices – practical.

Battery Life

With noise-cancelling switched on (highest level), the Liberty 4 played for just five hours and 18 minutes. That’s a good value, but some similarly priced competitors like the JBL Reflect Aero TWS already crack the ten-hour mark. On the other hand, the True Wireless headphones score points with their fixed charging time. Ten minutes in the charging case gives the Anker in-ears two hours and 18 minutes of power. The transport case visually matches the stylish earpieces, and Anker has taken shape from the Soundcore Liberty Air 2 Pro. The handy box has a high-quality finish and can even be powered wirelessly using an inductive charging pad. A white light on the front flap that can be pushed up provides information about the current charging status. The LEDs on the rubber ends of the headphones are efficient. This makes it easier to remove the in-ears in a dark environment.

Conclusion

The Soundcore Liberty 4 are the best wireless in-ears from Anker to date. The chic in-ears are especially exciting for sporty music fans, as they have practical extras such as a heartbeat sensor and a water-resistant housing (IPX4). The dominant bass has the power to propel the wearer during daily workouts. For normal listening on the couch, however, they seem a little too brisk. The sound character also focuses on the treble. These are nice and clear but also quite sharp. The Liberty 4’s battery life is not at its best. After five hours and 18 minutes, the headphones run out of battery. This is a shame, as the very pleasant wearing comfort invites you to listen to music for hours.
