Soundcore Liberty 2 Pro Review • Excellent sound and battery life

Soundcore Liberty 2 Pro

The Soundcore Liberty 2 Pro is Anker’s new headphone and the world’s first model based on the ACAA (Astria Coaxial Acoustic Architecture) speaker system. The headset combines a dynamic and armature driver: the first is responsible for bass, and the second is for mid and low frequencies. This allows you to achieve high sound quality in a compact package.

The main characteristics of the model:

  • Driver: ACAA (Astria Coaxial Acoustic Architecture)
  • Driver size: 11mm dynamic driver and balanced armature driver x2
  • Resistance: 16 ohm
  • Frequency Response: 20Hz-20KHz
  • Working time: 8 hours on a single charge, 32 hours from the case
  • Quick charge: 10 minutes in case = 2 hours runtime
  • Quad microphone system for noise cancellation during calls
  • 7 pairs of pads and 3 pairs of wing attachments included
  • Equalizer HearID
  • Bluetooth 5.0, Qualcomm aptX codec


The first thing you notice when unpacking your headphones is the unusually large charging case. It has a rather original design, which we have not seen in other TWS models: the lid here slides to the side, and does not open upward, as usual. It is incredibly pleasant to turn it in your hands: the case is somewhat reminiscent of old slider smartphones.

Almost all the space in the case is taken by headphones – also rather big. However, they sit comfortably in your ears, especially if you choose the right ear pads and wings: the headset comes with eight pairs of additional earpieces of different sizes.

Due to its shape, the headset fits securely in the ears and does not fall out even when moving: so with the Liberty 2 Pro you can safely play sports or run. Also on each earphone there is a button (mechanical), with which you can pause or start a track.


When connected, the Liberty 2 Pro use Bluetooth 5.0 and the aptX codec. Interestingly, if the smartphone is also equipped with the fifth Bluetooth, then the headphones are recognized as two devices – separately left and right. If the phone cannot work simultaneously with two connections, then only the main, right earpiece connects to it, and the signal goes to the left one from it.

If you remove or take out one of the earbuds, the music continues to play. So you have to be careful and remember to turn off the sound. At least so as not to waste the battery: both a smartphone and a headset.

When you first connect to your smartphone, you should install the Soundcore application: through it, the current firmware will fly to the headset. In addition, here you can customize the equalizer to your taste or choose one of 22 presets for different musical genres. There are also separate settings “from the professionals” – they were created by producers with a Grammy award.

One of the most exciting features of the Liberty 2 Pro is the ability to tailor the sound to your hearing using Hear ID technology. It works like this: turn on the headphones, go to a quiet place and run the test. The beeps corresponding to different bands will be output to the left and right headphones in turn. If the user hears sounds, then clicks on the screen, if not, releases the button. It often happens that a person does not recognize certain frequencies: it depends on age, hearing characteristics and the body as a whole. Based on the test results, Hear ID creates a personalized profile based on your hearing capabilities.

Of course, we checked how Hear ID works. But the result between the “before” and “after” settings was not particularly noticed – most likely, only people with very good or very poor hearing will understand the difference.

The headphones can also be used as a headset: for noise cancellation during a call, a four-microphone system and technology from Qualcomm are used. The headset recognizes the voice of the interlocutor and adds volume to him so that you can hear him in any environment. External sounds are muted at the same time.


Before evaluating the sound of the Soundcore Liberty 2 Pro, let’s just remind that they were approved by 10 music producers who received Grammy – and these guys certainly know about music.

We liked the sound too – especially if you include presets for different genres. The sound is quite clean and balanced, and the bass is clearly felt in electronic music – a separate dynamic driver does its job. Sound evaluation is still a very subjective thing. Therefore, it’s great that everyone can customize their own profile and hear the track at its “best” – with adjustments to their own ears.

In terms of operating time, the headphones beat all records. They can work on a single charge up to 8 hours, which is a lot for the TWS model. The case is enough for three more full charges: in total, we get 32 ​​hours of playback at medium volume. Even if you have a long flight or a couple of days on the train, the headphones will survive it.

Ten minutes of charging is enough for two hours of use, thanks to fast charging via USB-C. The charge level can be determined by the number of active LEDs on the case (there are three in total), which is quite convenient.


These headphones are a great choice for all music lovers. In terms of sound quality, the Liberty 2 Pro can easily compete with current Sony and Sennheiser models, which cost at least twice as much. In addition, this headset “lives” on a single charge as much as 8 hours, and also sits comfortably in your ears. If you need headphones for sports, you don’t have to worry about them falling out during training. The model has one noticeable drawback – the headphones do not recognize when they are removed and do not stop the music. But you can put up with this minus, given all the advantages of the gadget and a very tempting price.
