These headphones were replaced by the Anker Soundcore Liberty 3 Pro Truly Wireless

The Anker Soundcore Liberty 2 Pro are Anker's highest-end truly wireless headphones. Their battery life is nearly 7 hours, which is great for truly wireless headphones, and they have a very stable fit that makes them good for the gym as well. They're compatible with the great Soundcore app, which gives you access to a graphic EQ as well as presets, but their excited out-of-the-box sound profile should please fans of most genres.

Our Verdict

6.3 Neutral Sound

The Anker Soundcore Liberty 2 Pro are decent headphones for neutral sound. Their out-of-the-box sound profile isn't flat, but has an excited, V-shaped profile that should be pleasing to most people but isn't the most accurate. Luckily, their companion app gives you access to an 8-band graphic EQ so you can customize the sound to better suit your personal preferences.

Pros
  • Great battery for truly wireless headphones.
  • Good companion app with graphic EQ and lots of presets.
  • Very stable fit.
Cons
  • Sub-par recording quality.
  • Noise isolation performance is only acceptable.
7.3 Commute/Travel

The Anker Soundcore Liberty 2 Pro are a decent choice for commuting or traveling. Due to their truly wireless design, they're quite small and portable, and are comfortable enough to be able to wear for longer periods without fatigue. Unfortunately, they don't have ANC, and they don't do a great job at blocking out the low engine rumbles of a plane or bus.

Pros
  • Great battery for truly wireless headphones.
  • Good companion app with graphic EQ and lots of presets.
  • Very stable fit.
Cons
  • Sub-par recording quality.
  • Noise isolation performance is only acceptable.
8.1 Sports/Fitness

The Anker Soundcore Liberty 2 Pro are a great pair of sports headphones. They come with six different size tips as well as three sizes of stability fins to help you find a secure and stable fit; once you do they feel very stable in your ears and likely won't fall out while working out. They're also rated IPX4 for water resistance, though we don't currently test for this.

Pros
  • Great battery for truly wireless headphones.
  • Good companion app with graphic EQ and lots of presets.
  • Very stable fit.
Cons
  • Sub-par recording quality.
  • Noise isolation performance is only acceptable.
6.6 Office

The Anker Soundcore Liberty 2 Pro are okay headphones for using in the office. Their 7-hour battery life will almost get you through an entire work-day, and they do a good job at passively blocking out background chatter to help keep you motivated. They aren't the most comfortable, but thanks to their design, they're better than some other in-ear options. They also leak very minimal audio, so you should be able to listen to your music fairly loud without bothering those around you.

Pros
  • Great battery for truly wireless headphones.
  • Good companion app with graphic EQ and lots of presets.
  • Very stable fit.
Cons
  • Sub-par recording quality.
  • Noise isolation performance is only acceptable.
5.3 Wireless Gaming

The Anker Soundcore Liberty 2 Pro aren't recommended for wireless gaming. These headphones are Bluetooth-only and aren't compatible with an Xbox One or PS4. While you can connect them to a Bluetooth-enabled PC, their latency is likely too high to be used for gaming.

5.2 Wired Gaming

The Anker Soundcore Liberty 2 Pro are Bluetooth-only headphones that can't be used wired.

6.2 Phone Calls

The Anker Soundcore Liberty 2 Pro are mediocre for phone calls. Like most Bluetooth headphones, their microphone is disappointing and your voice sounds thin and muffled to the person you're speaking to. If you're taking a call in a moderately noisy environment, your voice can also sound much quieter compared to loud sounds around you.

Pros
  • Great battery for truly wireless headphones.
  • Good companion app with graphic EQ and lots of presets.
  • Very stable fit.
Cons
  • Sub-par recording quality.
  • Noise isolation performance is only acceptable.

Compared To Other Headphones

The Anker Soundcore Liberty 2 Pro are a good option if you like truly wireless headphones. They're the highest-end truly wireless in-ears that Anker makes and have a lot of features and an impressively premium look and feel. Unfortunately, they don't have ANC like some higher-end options like the Sony WF-1000XM3 Truly Wireless or the Apple AirPods Pro, but they're available for significantly cheaper and overall provide a good price-to-performance ratio. See our recommendations for the best truly wireless earbuds, the best wireless earbuds, and the best wireless earbuds for running.

The Anker Liberty 2 Pro are decently stylish and look fairly premium for a pair of budget-conscious truly wireless headphones. They look similar to the Sony WF-1000XM3 when they're in the ear and our unit have a nondescript, sleek black and dark grey matte finish, though they're also available in white. Unfortunately, due to their design, they protrude quite a bit out of the ears.

The Anker Soundcore Liberty 2 Pro are decently comfortable. Thanks to their design, the majority of the earbud sits outside of your ear so it shouldn't put too much pressure and cause fatigue after extended listening periods. Anker includes seven different size tips as well as three sizes of stability fins to help you find the best fit.

The Anker Liberty 2 Pro's controls are sub-par. While their default settings are easy to figure out, and the buttons are in an easy-to-click spot on the top of the earbuds that doesn't push them into your ear canal, unfortunately, they give minimal feedback. On the upside, all four available buttons (double-tap and long hold on each ear) are re-programmable within the app. While you can map volume control to the buttons, unfortunately, it requires you to either double tap the button or hold it for 2 seconds, to adjust the volume by one level, and you can't hold to continuously raise or lower the volume.

Like most in-ear headphones, the Soundcore Liberty 2 Pro 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.

The Anker Soundcore Liberty 2 Pro's charging case is great. It feels quite premium with a nice matte finish and includes wireless charging capabilities that should work with any Qi-enabled charger. It can also be charged via USB-C and there's a rubber stopper to prevent the port from getting dust and moisture in it. The case has a unique sliding lid that feels quite durable and should help prevent the case from accidentally opening.

Build Quality

The Anker Soundcore Liberty 2 Pro's build quality is good. The earbuds and the case are both made of dense, good quality plastic and feel fairly premium. While the case feels quite sturdy, the weak point would likely be the sliding lid. While it feels durable enough, it could potentially break if dropped on the wrong angle, or with enough force, though it's unlikely. The headphones are rated IPX4 for water resistance, though we don't currently test for this.

Stability

These headphones feel very stable in your ear. They come with a wide array of tips and stability fins to help achieve a proper fit, and when you do, they should stay in even while running or working out.

The Anker Soundcore Liberty 2 Pro have an excited sound profile out-of-the-box, with their bass and treble raised and their mid-range recessed. While it isn't the most neutral and balanced, it's tuned well for a wide variety of genres and should please most people. They're also compatible with Anker's Soundcore app which gives you access to a wide variety of EQ presets as well as a graphic EQ to fine-tune their sound to suit your personal preferences.

The peaks and dips performance of the Anker Soundcore Liberty 2 Pro is good. The slight peak in high-bass likely shouldn't be too audible but may cause some slight boominess. There's a large peak in high-mid and low-treble, and some peaks and dips through the treble range which may affect the presence of some vocals, but their biggest peaks are in high enough frequencies that they likely shouldn't be audible by most.

The stereo imaging of the Anker Soundcore Liberty 2 Pro is excellent. Their weighted group delay is well below the audibility threshold which should ensure a tight bass and a transparent treble reproduction. The L/R drivers of our test unit were also extremely well-matched, which 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 noise isolation of the Anker Soundcore Liberty 2 Pro is decent. Unfortunately, they don't have ANC and only block noise passively. While they do a great job at blocking out speech and background chatter, they don't do much to help block the low engine rumble of bus or plane engines. If you're looking for a pair of truly wireless headphones with an ANC feature, try the Samsung Galaxy Buds Pro Truly Wireless.

Update 11/10/2021: These headphones have been updated to test bench 1.5. In this update, we made changes to the way we test noise handling. We now use a subjective evaluation of our audio clips. This new method has resulted in different results than what we had reported in our previous test bench. As a result, the scoring of this box has changed, and we have updated our results.

The noise handling of the microphone is satisfactory. The person on the other end of the line should have no problem hearing you in quiet situations. However, it's harder to hear your voice in a moderately loud environment like a busy street as the volume of speech is drastically reduced.

The battery life of these headphones is passable overall, but very good for truly wireless headphones. Their continuous battery life of almost 7 hours is much longer than the Anker Soundcore Liberty Air 2 Pro Truly Wireless, and their case gives an additional three charges, which is good. Unfortunately, the headphones connect to your device as soon as the lid is opened, which is somewhat common for truly wireless headphones, but may cause the battery to drain if the case accidentally opens.

You can also use the app to button-map the four available button combinations.

Update 11/10/2021: These headphones were updated to Test Bench 1.5 and their latency values have changed. Our previous Test Bench 1.4 measurements reported 'PC Latency (aptX)' at 297 ms, 'iOS Latency' at 139 ms, and 'Android Latency' at 97 ms. However, our new test bench uses an average of three measurements instead of one, resulting in 275 ms of latency on PC (aptX), 41 ms on iOS, and 25 ms on Android. As a result, we have updated our text to better reflect test bench 1.5 measurements.

The Anker Liberty 2 Pro are Bluetooth-only truly wireless headphones that support aptX, which is good. Unfortunately, our Bluetooth dongle had issues connecting to these headphones, meaning we couldn't test their SBC latency. However, considering how 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. That said, their latency on iOS and Android devices is much lower. However, some apps and devices compensate for latency differently, and your real-life experience may vary.
