The Anker SoundCore Liberty Air 2 are a decent pair of truly wireless headphones that are a good upgrade over the previous version, offering some high-end features like wireless charging and a dedicated companion app. They have a well-balanced sound profile that has a little extra kick of bass, but should be versatile enough for most genres. They also isolate a decent amount of background chatter and have an amazing battery life for truly wireless headphones.

Our Verdict

7.3 Mixed Usage

The [nolink:Anker SoundCore Liberty Air 2] are decent truly wireless in-ears for mixed usage. They're decently comfortable for in-ears and have a good stable fit that makes them good for sports. They block a fair amount of background chatter and have a long battery life, making them good for office use as well. Their sound profile is versatile enough for most music genres, and they have a dedicated companion app with 20 EQ presets to match your personal preference.

7.2 Neutral Sound

The [nolink:Anker SoundCore Liberty Air 2] are okay for neutral sound. While their sound profile is decently well-balanced, it's a little bass-heavy and their mid-range is slightly recessed. Like all closed-back in-ears, they also have a very poor soundstage. On the upside, their harmonic distortion and imaging performances are both very good.

See our Neutral Sound recommendations
7.8 Commute/Travel

The [nolink:Anker SoundCore Liberty Air 2] are good headphones for commuting or travel. Even without ANC, their noise isolation performance is quite good, though they'll block out background chatter better than plane or train engines. They're decently comfortable for in-ear headphones and are extremely portable thanks to their truly wireless design. On the downside, they won't quite last a full day off a single charge, though this is normal for truly wireless headphones, and they can be charged five additional times from their case, which is great.

See our Commute/Travel recommendations
8.1 Sports/Fitness

The [nolink:Anker SoundCore Liberty Air 2] are great headphones for fitness use. Once you find the right sized silicone tip, they feel quite stable in your ear and will likely be able to withstand most workouts without falling out. They're also fairly comfortable and have a decent touch-sensitive control scheme so you can change your music without taking out your phone. They're rated IPX5 for sweat and water resistance, though we don't test for this.

7.0 Office

The [nolink:Anker SoundCore Liberty Air 2] are decent headphones for office use. They do a very good job of blocking out background chatter, which will help you stay focused at work. Unfortunately, their battery lasts just under 6.5 hours, meaning you'll likely have to take a break to charge them in the middle of the day. They also may not be the most comfortable for everyone due to their in-ear fit.

See our Office recommendations
5.7 Wireless Gaming

The [nolink:Anker SoundCore Liberty Air 2] aren't recommended for wireless gaming. They can only be used via Bluetooth, which means they aren't compatible with Xbox One of PS4. While they'll connect to Bluetooth-enabled PCs, their high latency may not be suitable for gaming.

See our Wireless Gaming recommendations
5.6 Wired Gaming

The [nolink:Anker SoundCore Liberty Air 2] are Bluetooth-only headphones that can't be used wired.

6.7 Phone Call

The [nolink:Anker SoundCore Liberty Air 2] are okay for phone calls. Like most Bluetooth headphones, their microphone will make your voice sound slightly muffled and lacking in detail. Their noise handling is also sub-par, meaning the person on the other end of the line won't be able to hear you in even moderately noisy environments.

Test Results

Design
Style

The Anker SoundCore Liberty Air 2 have a very similar style to the first generation. Our unit has a nice matte black finish which shouldn't attract as many fingerprints as the previous version's glossy black finish, and they have a small splash of red color on the bottom of the stems. Overall, they look slightly more premium than the first-gen SoundCore Liberty Air.

The Liberty Air 2 are decently comfortable, though their in-ear fit may not be for everyone. They come with five different silicone tip sizes to help ensure you get the most comfortable fit.

The Anker SoundCore Liberty Air 2's touch-sensitive control scheme is decent and significantly improved over the previous model. Unfortunately, the headphones only offer four programmable controls which can be customized within the companion app: a double-tap and long hold on each ear. There's no feedback on the touch controls, and you only get audio cues when powering on/off or pairing the headphones. If you prefer physical buttons, check out the more affordable Anker SoundCore Life P2.

Breathability

Like most in-ear headphones, the Liberty Air 2 don’t trap any heat inside your ear, so you shouldn’t notice a difference in temperature when wearing them. This makes them a good option for sports as you shouldn’t sweat more than usual.

These truly wireless headphones are very small and lightweight and have excellent portability. Their charging case is also on the smaller side and should easily be able to fit into most pockets or bags.

The Anker SoundCore Liberty Air 2's charging case is great. It feels slightly more premium than the previous model thanks to its matte finish, and it now includes wireless charging capabilities that should work with any Qi-enabled charger. It's worth noting that while we don't test this, we tried it on various wireless chargers around the office and found that it seems to be very susceptible to placement on the charging pad, and we had to place it in just the right spot to ensure charging.

Build Quality

The Anker SoundCore Liberty Air 2's build quality is good. Both the earbuds and the case feel less plasticky and slightly more premium than the Anker SoundCore Liberty Air. The case feels sturdy enough, with a good quality hinge that doesn't feel wobbly or loose, and overall it should be able to withstand a few drops or bumps without sustaining damage. The headphones are also rated IPX5 for sweat and water resistance, though we don't currently test for this.

Design
Stability

The Anker SoundCore Liberty Air 2 feel quite stable in your ear once you find the proper fit with the included tips. Once you achieve a decent seal, the buds likely will stay in your ear even during runs or light workouts. Unfortunately, they don't have optional stability fins, which would help improve this even further.

The Anker SoundCore Liberty Air 2 have a fairly well-balanced sound profile that's slightly bass-heavy but without the bass being too over-powering. Unfortunately, their mid-range is slightly recessed, which may push leads and vocals to the back of the mix. Overall, these headphones will likely please fans of thumpy bass, though they should be versatile enough for most genres. They also have a companion app with a ton of available presets, so you can pick the one that best suits your personal preference.

The frequency response consistency is outstanding. Once you achieve a proper fit and seal with the included tips, you'll likely get consistent bass and treble response every time you use the headphones.

The Anker SoundCore Liberty Air 2's bass accuracy is excellent. They're slightly overemphasized in the low-bass range which will give a bit of thump and should please fans of dubstep or EDM. The rest of the range evens out a bit more, giving them a deep, well-balanced, and punchy bass response that shouldn't sound muddy or boomy.

The Liberty Air 2's mid accuracy is good. While this range is mostly flat, unfortunately it's underemphasized throughout the entire frequency range. This results in leads and vocals that may sound slightly distant, weak, and pushed back in the mix.

The peaks and dips performance is great. They're reasonably well-balanced and stay fairly flat throughout all frequency ranges. However, there's a bit of a dip throughout the entire mid-range, which may make leads and vocals sound ever so slightly weak and distant. There are also two peaks in the treble range, though these are in high enough frequencies that they likely won't be too audible for most people.

The Liberty Air 2's stereo imaging is excellent. The group delay is below the audibility threshold for the entire range, ensuring a tight bass and transparent treble reproduction. Also, the L/R drivers of our test unit were very well-matched. 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.

Like all closed-back in-ear headphones, their soundstage is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds is in such a way that fully bypasses the pinna and doesn't interact with it.

The Liberty Air 2's weighted harmonic distortion is very good. All frequencies fall within very good limits, which should result in a clear and pure audio reproduction.

The Liberty Air 2's noise isolation performance is quite good. They don't have ANC and only block noise passively, though they do a good job of this assuming you've got a proper seal with the included tips. They do a great job at blocking out background chatter, making them a good choice for the office, though, unfortunately, they do a sub-par job at blocking out the rumble of a bus or plane engine.

The Liberty Air 2's dedicated companion app is decent. While it looks nice and has great visual appeal, unfortunately it doesn't offer too many customization options, with 20 EQ presets instead of a graphic EQ. The app also contains Anker's HearID feature, which creates an EQ personally for you. While we don't officially test this, we tried it in the office and found it didn't make much of a difference. The app also allows you to button-map the four available touch-sensitive buttons.

The Liberty Air 2 are Bluetooth-only truly wireless headphones. Unlike the first generation, these headphones now support aptX, which is a nice addition.

Note: Unfortunately, our Bluetooth dongle encountered issues and we were unable to test their SBC latency. Considering how slightly high their aptX latency is, we'd expect their SBC performance to be slightly worse and they likely aren't a good option for watching video content. We'll update this score when we can properly test latency. If you want more gaming-oriented truly wireless headphones, check out the Razer Hammerhead True Wireless.
