The Anker Soundcore Liberty Air 2 Pro Truly Wireless are the upgraded variant of the Anker SoundCore Liberty Air 2 Truly Wireless. With this update, Anker has added a customizable active noise cancelling (ANC) feature which can help cut down a great amount of ambient noise around you. Otherwise, these headphones have a similar build and design as their base model. They have a bass-heavy sound profile that can be tweaked using their companion app's graphic EQ or presets and a comfortable fit. However, their overall battery life falls short of their advertised playtime.

Update 11/15/2021: We originally reported that these headphones have a dynamic transducer. However, they have a hybrid dynamic and balanced armature transducer. We have updated our review to reflect these changes.

Our Verdict

6.9 Neutral Sound

TheĀ Anker Soundcore Liberty Air 2 Pro areĀ alright for neutral sound. Their default sound profile is bass-heavy with a recessed mid-range and piercing sibilants. Luckily, if you prefer a more neutral sound, their companion app offers a graphic EQ plus presets so that you can tweak their sound to your liking. They also have consistent bass and treble delivery.

Pros
  • Great, adjustable active noise cancelling feature.
  • Graphic EQ and presets.
Cons
  • Disappointing battery performance.
  • Closed-off soundstage.
7.9 Commute/Travel

TheĀ Anker Soundcore Liberty Air 2 Pro areĀ good for commute and travel. They're decently comfortable, very portable, and have a great active noise cancelling feature that you can also adjust to better match the noise around you. However, around 3.5 hours of continuous battery life is quite low and may not be enough for long trips.

Pros
  • Great, adjustable active noise cancelling feature.
  • Well-built and portable design.
Cons
  • Disappointing battery performance.
8.1 Sports/Fitness

TheĀ Anker Soundcore Liberty Air 2 Pro areĀ great for sports and fitness. They're decently comfortable, very breathable, and have a stable fit suitable for moderate exercises like jogging. Since they don't have any cables, it's hard for something to snag them and pull them out of your ears. However, they may fall out during more intense exercise.

Pros
  • Great, adjustable active noise cancelling feature.
  • Stable and very breathable fit.
Cons
  • Disappointing battery performance.
7.1 Office

TheĀ Anker Soundcore Liberty Air 2 Pro areĀ fair for office use. They're decently comfortable and have an adjustable ANC that can help cut down ambient chatter. However, their 3.5-hour continuous battery life falls short of their advertised battery life, and won't last through your 9-5 workday without a couple of recharges throughout your shift.

Pros
  • Great, adjustable active noise cancelling feature.
  • Well-built and portable design.
Cons
  • Disappointing battery performance.
  • No NFC or multi-device pairing.
5.6 Wireless Gaming

TheĀ Anker Soundcore Liberty Air 2 Pro areĀ truly wireless headphones and aren't suitable for wireless gaming. While they can be used on Bluetooth-enabled PCs, their high latency on PCs makes them less than suitable for gaming.

5.5 Wired Gaming

TheĀ Anker Soundcore Liberty Air 2 Pro areĀ truly wireless headphones and can't be used wired.

6.4 Phone Calls

TheĀ Anker Liberty Air 2 Pro areĀ alright for phone calls. They use an integrated microphone, but its recording quality is poor, so your voice sounds thin, muffled, and unnatural. On the upside, the mic does an excellent job of separating your voice from noisy environments. Their ANC is able to cut down a lot of noise around you, so you can focus on your call.

Pros
  • Great, adjustable active noise cancelling feature.
  • Well-built and portable design.
Cons
  • Poor recording quality.
  • Disappointing battery performance.

Update 02/17/2022: A firmware update was released for these headphones that changed their onboard controls. With the newest firmware (version 5.63), you can use the app to enable a one-tap control on each earbud that raises or lowers the volume by default. The results and text have been updated to reflect this.

TheĀ Anker Soundcore Liberty Air 2 Pro have decent controls. The touch-sensitive surfaces aren't the most intuitive to use out-of-the-box, but you can remap the controls in the companion app. There are also some beeps when registering commands. Ī’y default, a single tap raises or lowers the volume. You can tap twice on the left bud to skip to the next track while the same action on the right bud plays and pauses your audio. You can also hold down either bud for two seconds to turn their ANC on and off.

However, we couldn't get the voice prompt to work on our model. You can only turn off the headphones by putting them in the case too, and if you want to manually pair them via Bluetooth, you have to put them back in their case and hold the button on the case.

Build Quality

The Anker Soundcore Liberty Air 2 Pro are well-built and overall have a similar build quality as the Nothing Ear (1) Truly Wireless. They're made of plastic and a silicone-like material but seem sturdy enough to withstand a few accidental drops without too much of an issue. They're also rated IPX4 for water resistance, although we don't currently test for this. That said, the weak points of these headphones are that the ear tips could rip. The carrying case's lid could also break over time.

Stability

The Anker Soundcore Liberty Air 2 Pro are stable headphones. Once you get a good seal using one of the many pairs of differently-sized ear tips included, they should stay in your ears during a jog or run. However, they lack stability fins, so they may fall out during more intense physical exercise. If you're looking for more stable in-ears, try the Google Pixel Buds A-Series Truly Wireless instead.

The Anker Soundcore Liberty Air 2 Pro have a bass-heavy sound profile. They deliver extra thump, rumble, and boom, which is great for genres like EDM and hip-hop. However, part of the mid and treble-range is under-emphasized, resulting in weakened and veiled vocals and lead instruments. However, sibilants like cymbals are piercing. If you prefer a different sound profile, their companion app offers a graphic EQ and presets.

Also, the L/R drivers of our test unit are very well-matched in amplitude, frequency, and phase response. This is important for the accurate placement and localization of objects (like voices or footsteps) in the stereo image. These results are only valid for our unit, and yours may perform differently.

Note: While there are a lot of peaks and dips in the phase response graph, it isn't fully representative of their actual performance. The left and right drivers are very well-matched, which results in a stable stereo image.

The Anker Soundcore Liberty Air 2 Pro have a bad passive soundstage, which is common for closed-back in-ear headphones. Due to their design, they bypass the outer ear, which is a big factor in creating an out-of-head or speaker-like soundstage. As a result, they have a small soundstage that seems like it's located inside of your head rather than as if it's coming from out in front of you.

The Anker Soundcore Liberty Air 2 Pro have a great noise isolation performance that can also be adjusted and customized via their companion app. When using their 'Transport' mode, their active noise cancelling (ANC) feature can help cut down a lot of bass-range noise like bus or plane engines. However, their passive noise isolation performance is actually better than their ANC performance throughout most of the mid and treble ranges. That said, they still cut down some ambient chatter around you and can block out high-pitched noise like the hum of an AC fan.

These headphones also offer three other kinds of ANC, but we don't currently test them. 'Outdoor' mode is advertised to help cut down traffic and wind noise, while 'Indoor' mode is more focused on reducing mid and treble-range noise like office chatter and the hum of fans. There's also a customizable 'wheel' setting, so you can find the right amount of noise isolation to fit your needs.

However, battery life can vary depending on usage, so your real-life experience may vary. Still, you may want to consider the Anker Soundcore Life A2 NC Truly Wireless or the Anker Soundcore Liberty 3 Pro Truly Wireless if you're looking for truly wireless in-ears with significantly better battery performance. While they don't have a power-saving feature, you can use one earbud while the other one charges.

The Anker Soundcore Liberty Air 2 Pro have satisfactory Bluetooth connectivity.

However, their latency on iOS and Android is a bit lower, which is good if you like to stream video content. It's worth noting that apps and devices compensate for latency differently, so your real-life experience may vary.
