The Anker SoundCore Liberty Air True Wireless are mixed usage headphones and are very versatile for everyday casual use. Their truly wireless design resembles the Apple AirPods (1st generation) Truly Wireless, but with a glossier finish. They're very portable, and their in-ear fit blocks lots of ambient noise, which is nice for commuting and at the office. They have a fairly neutral sound profile and have an amazing wireless range. Unfortunately, truly wireless earbuds don’t have very long battery life, and their latency is too high for watching videos and gaming. On the upside, they offer great performance for their price, and most users should be pleased with them.

Our Verdict

7.1 Mixed Usage

The Anker SoundCore Liberty Air true wireless are decent for mixed usage. They're very versatile for everyday casual use, and critical listeners can appreciate their fairly neutral sound profile. They are portable and isolate a good amount of ambient noise, making them a good choice for commuting and the office. Their design is very breathable, and the fit is stable for more intense physical activities. However, some may find the in-ear fit to be tiring after a while. Their latency is also too high to be suitable for watching videos and gaming.

Pros
  • Very lightweight and portable design.
  • Fairly neutral sound profile.
  • Great isolation performance.
Cons
  • In-ear fit might not be for everyone.
  • No volume controls.
7.1 Neutral Sound

The Anker SoundCore Liberty Air true wireless are decent for neutral listening. They have a deep and accurate bass, a well-balanced mid-range, and a great treble. However, there’s a slight recess in the mid-range that barely nudges the vocals to the back of the mix, and their treble is a bit uneven on sibilances as some may lack detail and others might sound slightly sharp. Also, fans of heavier sound profiles might find the bass of these headphones to be on the lighter side. The in-ear design might not be the most comfortable for long listening sessions.

7.7 Commute/Travel

The Anker SoundCore Liberty Air are good for commuting and traveling. Their design is very portable and easy to carry around. They also isolate a good amount of ambient noise, including the rumble of bus and airplane engines. Unfortunately, the in-ear fit might not be ideal for long rides and flights, and their 4-hour battery life might not last you a long trip. On the upside, they don’t leak much, so you won’t have to worry about bothering people surrounding you with your music.

8.0 Sports/Fitness

The Anker SoundCore Liberty Air are great for sports. These truly wireless in-ears are very portable, and their fit is very stable if you can find the right tip size for your ears. They barely move around and shouldn’t pop out of your ears. Their design is also breathable, so you shouldn’t sweat more while wearing them.

6.9 Office

The Anker SoundCore Liberty Air are fair for office use. They create a great seal that blocks ambient chatter, letting you concentrate on your music and tasks. They also don’t leak, so colleagues shouldn’t hear what you’re listening to. Unfortunately, their battery life of one charge isn’t very long, and you’ll need to recharge them during the day with the case. The in-ear fit might not be comfortable for a whole workday, so you might need to take breaks here and there if you feel fatigued.

5.3 Wireless Gaming

The Anker SoundCore Liberty Air are poor for gaming. They shouldn't be used for gaming, as their latency is too high, and their microphone quality is sub-par if you play online with friends and teammates. Even if you’re not looking for a microphone, you shouldn’t use these headphones for video games.

5.2 Wired Gaming

The Anker SoundCore Liberty Air aren't suitable for gaming.

Compared To Other Headphones

Comparison picture

The Anker SoundCore Liberty Air are very versatile, truly wireless in-ears with a fairly neutral sound profile. They have a lightweight design, but they look like a cheaper version of the Apple AirPods (1st generation) Truly Wireless. They also have great isolation performance, which is great for commuting and to use at the office. Unfortunately, the in-ear fit might be fatiguing after long listening sessions, and their latency is high for watching videos and gaming.

See our recommendations for the best wireless earbuds under $100, the best true wireless earbuds, and the best budget wireless headphones.

Anker SoundCore Life P2 Truly Wireless

The Anker SoundCore Life P2 Truly Wireless are similar to the Anker SoundCore Liberty Air Truly Wireless. The Life feel slightly better-built with a more premium matte finish and have a longer battery life. On the other hand, the Liberty have better noise isolation and a slightly more neutral sound profile.

Anker SoundCore Liberty Air 2 Truly Wireless

The Anker SoundCore Liberty Air 2 Truly Wireless are better than the Anker SoundCore Liberty Air Truly Wireless. The Liberty Air 2 look very similar but have much better controls, a more premium-feeling design, a much better battery life, and a dedicated companion app. On the other hand, the first generation have a slightly better-balanced sound profile and are cheaper.

JLab Audio JBuds Air ANC Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are slightly better headphones than the JLab Audio JBuds Air ANC Truly Wireless. The Anker have a better-balanced sound profile and they can isolate more noise passively than the JLab with ANC on. However, the JLab are better-built and offer a longer continuous and total battery life. The JLab also have less latency on PC, iOS, and Android, although some apps compensate for latency differently.

SoundPeats TrueFree/True Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless in-ears than the SoundPeats TrueFree/True Wireless. The Anker sound profile is more neutral, but some may prefer the thumpy bass of the SoundPeats. The Anker also isolate a bit better, but not by much. The nice touch-sensitive control surface is better than the one-button layout of the SoundPeats since you don’t have to push the headphones deeper inside your ear canal. The Anker case has a lid that protects the headphones, which the SoundPeats’ case is lacking. On the other hand, the SoundPeats feel better made and their matte design isn’t as fingerprint prone as the Anker's glossy finish.

Apple AirPods (2nd generation) Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless and the Apple AirPods (2nd generation) Truly Wireless may look similar, but perform quite differently. The open-back Apple lack bass and don't isolate any noise, but have a more bright, spacious sound. On the other hand, the noise-isolating in-ear Anker have a more bass-rich sound but are less comfortable.

RHA TrueConnect Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are more versatile and cheaper than the RHA TrueConnect Truly Wireless. The Anker might not have volume control, but these in-ears have good audio reproduction. The two headphones are very similar, but the sound quality is what makes the Anker the best option. The Anker might feel a bit cheaper than the RHA due to their plastic and glossy build, but if you’re usually careful with your headphones, this shouldn’t be a problem. The RHA feel sturdier, but don’t have a standby mode like the Anker have.

JLab Audio JBuds Air Executive Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless earbuds for most people than the JLab Audio JBuds Air Executive Truly Wireless. The Anker isolate more noise and have a more neutral, balanced default sound profile. They don't have any onboard EQ presets though, like the JLab, and they don't have volume controls either. The JLab battery also lasts a bit longer, but they don't have any power-saving features.

Skullcandy Indy Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better mixed-usage truly wireless headphones than the Skullcandy Indy Truly Wireless. The Anker have a much better-balanced sound profile, and their fit isolates against more ambient noise than the Skullcandy. The Anker design is also a bit less bulky, making them easier to fit in most ears. On the other hand, the Skullcandy have volume controls, unlike the Anker. The Skullcandy microphone has a better recording quality for calls. However, our unit has noticeably mismatched drivers, and overall, the Anker offers better performance and value.

Anker Zolo Liberty+ Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless earbuds than the Anker Zolo Liberty+ Truly Wireless. The SoundCore are more comfortable, stable for sports, and their sound quality is slightly better as well. You also get more continuous playback time on the SoundCore and a more compact and portable case. On the other hand, you get an app that offers a few features with the Zolo, and they feel a bit better-built since they don’t have the same glossy and plastic feel of the SoundCore.

JLab Audio JBuds Air Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless headphones than the JLab Audio JBuds Air Truly Wireless. While they don’t have volume control, the Anker have a much better sounding audio reproduction, and their fit blocks out more ambient noise, which is good for commuting. The Anker come with a smaller case and offer better battery life, on top of taking less time to charge. However, their stalk design is a bit more fragile than the dense JLab and is slightly less stable for sports.

Apple AirPods (1st generation) Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better headphones than the Apple AirPods (1st generation) Truly Wireless. The Anker are more versatile, thanks to their closed-back design that helps isolate more noise, which is useful for commuting and using at the office. The Anker sound quality is also more accurate and follows our curve better. Thanks to the different tip sizes, they are also very stable in-ears for sports. On the other hand, the Apple feel better made, have a better battery life, and are more comfortable for most people. The Apple are also more open-sounding due to their open-back design and have noticeably lower latency.

Anker SoundCore Liberty Lite Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are slightly better truly wireless headphones than the Anker SoundCore Liberty Lite Truly Wireless. The Liberty Air have a more comfortable fit, and their audio reproduction is also flatter and more neutral. The Liberty Air also have a longer battery life and a power-saving feature. On the other hand, their glossy and plastic build gives them a cheaper feel than the Liberty Lite. The Liberty Lite also have physical buttons, but you need to push the headphones deeper in your ear to register commands, which doesn’t happen with the touch-sensitive control scheme of the Liberty Air.

JBL Endurance Peak True Wireless

The JBL Endurance Peak True Wireless and the Anker SoundCore Liberty Air Truly Wireless are both decent truly wireless in-ears. They’re both decently well-built and have similar batteries, lasting around four hours on a charge and charging in under an hour and a half. However, the Peak’s charging is a bit better since they have an auto-off timer. Both headphones also have a well-balanced, neutral sound profile, but the Anker have a more accurate treble response. The JBL have a sportier look with a better control scheme, but the Anker have a more casual look and are more comfortable with better isolation.

TREBLAB X5 Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless headphones than the TREBLAB X5 Truly Wireless. The Anker build is less bulky, their audio reproduction is more accurate, their fit blocks more ambient noise, and their battery life is slightly longer. However, the Anker have higher latency and don’t have volume control on the earbuds, which the TREBLAB have. The TREBLAB also come with fins for added stability during physical activities.

Altec Lansing True Evo Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless headphones than the Altec Lansing True Evo Truly Wireless. The Anker have a more neutral sound profile and isolate more ambient noise, making them a more versatile and better option for commuting. The Anker also have slightly better battery life, and their case is more compact. The Anker also support Bluetooth 5.0, which may translate into better range and connection stability. On the other hand, the Altec come with a good amount of tip options and feel less cheap than the glossy and plastic feel of the Anker.

Skullcandy Push Truly Wireless

The Anker SoundCore Liberty Air Truly Wireless are better truly wireless in-ears than the Skullcandy Push Truly Wireless. The Anker have a more lightweight design, and their case is more portable. The sound quality is more neutral, but some may prefer the heavy bass of the Skullcandy. The Anker isolate more noise and are more versatile for everyday casual use. However, the Skullcandy have a better control scheme that offers volume control, which the Anker lacks. The Anker also have a longer battery life on one charge and maxed out our testing facility for wireless range.

Anker SoundCore Spirit X Wireless

The Anker SoundCore Liberty Air Truly Wireless are more versatile than the Anker SoundCore Spirit X Wireless. The truly wireless design of the Liberty Air gets rid of the cable and has a more portable design. Fans of bass may prefer the sound profile of the Spirit X, but the Liberty Air has better overall sound quality. The fit of the Liberty Air is also better for isolating ambient noise than the Spirit X. However, the Spirit X have a longer battery life, and their ear-hook design is very stable for sports. With the Spirit X, you also get a nice in-line remote with volume controls, and they are rated IPX7. While the Liberty Air is rated IPX5 for sweat and water resistance.

Jabra Elite 65t Truly Wireless

The Jabra Elite 65t Truly Wireless and the Anker SoundCore Liberty Air Truly Wireless are both well-rounded pairs of truly wireless earbuds, although the Jabra have a slight edge. The Anker have fairly similar, well-balanced sound profile out-of-the-box, but the Jabra can be customized with the EQ in their companion app. Their battery performance is similar, and they both isolate around the same amount of noise as well. The Jabra can connect to two Bluetooth devices at once, though, and their microphone performance is better.

The Anker SoundCore Liberty Air are very low-profile, truly wireless in-ears with a similar design to the Apple AirPods (1st generation) Truly Wireless. They have the same long stalks that protrude outside your ears where you would normally have cables attached. They have a glossy finish that's fingerprint-prone and looks plasticky. They come in an all-black or all-white design.

The Anker SoundCore Liberty Air's in-ear fit is decently comfortable but might not be for everyone. They come with four silicone tip sizes for you to find the most comfortable fit. Also, these headphones are very lightweight, and you barely feel them inside your ears. Some may feel some fatigue after listening to them for a while.

The Anker SoundCore Liberty Air have a decent touch-sensitive control scheme. You get basic functionalities like call/music management and track skipping, but unfortunately, you don’t have any control over your listening volume directly on the earbuds, so you have to change it on your device. On the upside, the control scheme is very easy to use and responsive, but you don’t get any feedback from most commands. You get small audio cues for powering on/off the headphones and during the pairing procedure, but that’s it. Unfortunately, they're not as easy to use as the TREBLAB X5 Truly Wireless or the Jabra Elite Sport Truly Wireless, which have physical buttons with more functionalities. If you like touch-sensitive control schemes, but volume control is a must-have, take a look at the Skullcandy Indy.

Like the Altec Lansing True Evo and most in-ear headphones, the Anker SoundCore Liberty Air 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 during physical activity.

The Anker Soundcore Liberty Air come with a nice hard case that's also a charging station for the headphones. It protects the headphones against scratches and impacts, but it isn’t waterproof like the earbuds are. The lid closes by magnetic force, but it opens very easily, and the buds might fall out with a significant impact. On the upside, you get a battery life indicator on the case.

Build Quality

The Anker SoundCore Liberty Air are decently well-built, truly wireless headphones. They're made of glossy plastic that feels cheap, but the buds are dense enough to survive accidental drops without too much damage. The case is also decently made and should help protect the headphones. The earbuds are also rated IPX5 for sweat and water resistance, but we don't currently test for this. However, the case isn't waterproof. For slightly better-built headphones without a glossy finish, take a look at the dense and solid Anker SoundCore Liberty Lite Truly Wireless or Anker Zolo Liberty+ Truly Wireless. If you like the chalk design, look at the RHA TrueConnect, the Anker SoundCore Liberty Air 2 Truly Wireless, or the SoundCore Life P2 Truly Wireless.

Stability

The Anker SoundCore Liberty Air's stability is very dependent on the ear tip you use. If you can achieve a decent seal and fit, the buds barely move inside your ears and are suitable for running or working out. On the upside, their truly wireless design removes the risk of a cable getting hooked on something and pulling out the headphones.

The Anker SoundCore Liberty Air's bass accuracy is excellent. The response is flat and virtually flawless throughout the range, and mostly within 1.5dB of our neutral target. The LFE (low-frequency extension) is at 10Hz, which is also excellent. Overall, the bass is deep, thumpy, and punchy, while being well-balanced, making them suitable for all genres of music, including the bass-heavy ones.

These headphones' stereo imaging is outstanding. Their weighted group delay is at 0.16, which is very low. The group delay graph also shows that the entire response is well below the audibility threshold. Ithis ensures a tight bass and a transparent treble reproduction. Also, the L/R drivers of our unit are well-matched in frequency, amplitude, and phase response. This is important for the accurate placement and localization of objects (voices, instruments, video games effects) in the stereo image. Note that these results are only valid for our unit, and yours may perform differently.

These headphones' soundstage is bad. 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 fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds.

The Anker SoundCore Liberty Air's noise isolation performance is great. Even if they don’t have any ANC feature, they passively block a good amount of ambient noise. They achieved about 11dB of isolation in the bass range, where engine rumbles sit, which is poor, and there seems to be a weak spot around the 200hz mark. In the mid-range, important for blocking ambient chatter, they achieved isolation of 23dB, which is outstanding. They provide about 37dB of isolation in the treble range, which is also fantastic.

With the music at 100dB SPL, the leakage at 1 foot away averages at 23dB SPL and peaks at 33dB SPL, which is roughly as loud as a very calm room and well under the noise floor of an average office.

The Anker SoundCore Liberty Air’s microphone has a sub-par recording quality. The LFE (low-frequency extension) of 386Hz means speech recorded or transmitted sounds noticeably thin. The HFE (high-frequency extension) is poor and results in speech that's muffled and lacking in detail. It also negatively affects the understandability of speech but should still be understandable in very quiet environments.

On the upside, the headphones have a power-saving feature, and they enter a standby mode if they are connected to a device, but no audio is playing. If the headphones are not connected to a device but are powered on, they automatically turn off in 2 minutes.

The Anker SoundCore Liberty Air support Bluetooth 5.0, so you might get even better results in wireless range and connection stability if your audio source supports Bluetooth 5.0 too. Unfortunately, they can only be connected to one device at a time and don’t support NFC. You can also use the right earbud alone if you want, but not the left one.

Their latency is too high to watch video content or for gaming. It is also higher than the average Bluetooth headphones that usually measure around 200-220ms of delay. On the upside, some video content apps like YouTube and Netflix seem to compensate for the delay, so you shouldn’t notice it too much.
