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

6.8 Mixed Usage

The Anker Soundcore Liberty 2 Pro are a decent option for mixed usage. They're great for using in the gym thanks to their stable fit and IPX4 rating for water resistance, though we don't currently test this. They have a nearly 7-hour battery life which should last you almost an entire work day, and they do a good job at blocking out chatty coworkers to help keep you concentrated in the office.

6.1 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.

See our Neutral Sound recommendations
7.3 Commute/Travel

The Anker Soundcore Liberty 2 Pro are a fairly good 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.

See our Commute/Travel recommendations
8.0 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.

See our Sports/Fitness recommendations
6.5 Office

The Anker Soundcore Liberty 2 Pro are decent 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.

See our Office recommendations
5.1 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.

See our Wireless Gaming recommendations
4.9 Wired Gaming

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

5.2 Phone Calls

The Anker Soundcore Liberty 2 Pro aren't recommended for phone calls. Like most Bluetooth headphones, their microphone is disappointing and your voice will sound thin and muffled to the person you're speaking to. It will also be difficult for them to hear you if you're in even a moderately noisy environment.

Test Results

Style

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.

Breathability

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.

Design
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.

Design
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 bass accuracy of the Anker Soundcore Liberty 2 Pro is excellent. They're slightly overemphasized throughout almost the entire range which will add a bit of extra thump, but they remain flat and balanced without any spikes or dips.

The mid accuracy of the Anker Soundcore Liberty 2 Pro is okay. Their excited sound profile means that almost the entire mid-range is recessed, pushing most lead instruments and some vocals further back in the mix.

The treble accuracy of the Anker Soundcore Liberty 2 Pro is excellent. While there are several small peaks and dips throughout the range, overall it remains fairly balanced. This means that vocals and cymbals should sound present and shouldn't be piercing or painful.

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.

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 among the best that we've tested, 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.

The dedicated companion app for the Anker Soundcore Liberty 2 Pro is good. It offers 20 EQ presets as well as an 8-band graphic EQ to fully customize your sound. You can also use the app's HearID feature which will create an EQ personally for you, though we didn't notice much of a difference when trying it. You can also use the app to button-map the four available button combinations.

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 so we were unable to 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.

Compared to other headphones

Comparison picture

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.
