The Anker Liberty 3 Pro have a similar oval-shaped design to their predecessor, the Anker Soundcore Liberty 2 Pro Truly Wireless. They're mostly made of sleek plastic and look somewhat non-descript, although they stick out of your ears quite a bit. They come in four color variants if you prefer a different look: 'Midnight Black', 'Frost White', 'Dusk Purple', and 'Fog Gray'.

The Anker Soundcore Liberty 3 Pro's case is great. It's made of plastic, and there are three LED lights to indicate battery life. There's also a button on the back of the case in order to enter pairing mode. However, depending on how the silicone fins are placed on the buds, the case may not close or open properly.

The Anker Liberty 3 Pro's build quality is good. They're made of plastic and silicone but feel sturdy. They're also rated IPX4 for protection against splashes of water. They should survive a couple of accidental drops without taking too much damage. However, the case's lid can open if dropped.

—

The Anker Liberty 3 Pro have great stability. Once you achieve a good fit using the provided stability fins and ear tips, they shouldn't move around your ears, even during more intense physical activity.

Bass Amount

Treble Amount

The Anker Liberty 3 Pro have a v-shaped sound profile that delivers extra thump, rumble, and boom to mixes. At the same time, vocals and lead instruments are bright and sparkly. If you prefer a different sound, their companion app offers a graphic EQ and presets so that you can adjust their sound to your liking.

Avg. Std. Deviation

The Anker Soundcore Liberty 3 Pro's frequency response consistency is great. Assuming you achieve a good fit using the provided ear tips, you should get a consistent sound each time you use them.

Std. Err.

Low-Frequency Extension

Low-Bass

Mid-Bass

High-Bass

The bass accuracy is satisfactory. It's overemphasized across the range, so mixes have extra thump, rumble, and boom. However, some users may find they sound boomy and muddy.

—

Std. Err.

Low-Mid

Mid-Mid

High-Mid

The Anker Liberty 3 Pro's mid accuracy is excellent. The range is fairly flat and neutral, which results in present and clear vocals and lead instruments. However, a bump in the high-mid can make their upper harmonics sound harsh.

—

Std. Err.

Low-Treble

Mid-Treble

High-Treble

The Anker Soundcore Liberty 3 Pro's treble accuracy is passable. It's overemphasized across the range, resulting in harsh vocals and lead instruments. Sibilants like S and T sounds are also piercing.

—

Peaks

Dips

The peaks and dips performance is good. The peak in the mid-bass adds a touch of extra warmth to mixes, while a prolonged dip in the low to mid-mid nudges vocals and lead instruments to the back of your mixes. Another peak in the high-mid makes vocals and lead instruments sound a bit harsh, but a dip in the low treble hurts their comprehensibility and veils details. Another peak in the mid-treble makes sibilants like cymbals piercing.

Weighted Group Delay

Weighted Phase Mismatch

Weighted Amplitude Mismatch

Weighted Frequency Mismatch

The Anker Liberty 3 Pro's imaging performance is excellent. The group delay falls below the audibility threshold, resulting in tight bass and transparent treble reproduction. Our unit's L/R drivers are also well-matched in amplitude and frequency response, ensuring a balanced and stable stereo image. However, a peak in the phase response's high-mid to low-treble range can cause inaccuracies in the stereo image and can be audible with real-life content. That said, our results are only valid for our unit, and yours may perform differently.

Acoustic Space Excitation

The Anker Soundcore Liberty 3 Pro have a bad passive soundstage, which is to be expected for in-ear headphones. Due to their design, they fully bypass your outer ear, which needs to be activated by sound to produce an out-of-head or speaker-like passive soundstage. As a result, sound seems like it's coming from inside your head, and it isn't very immersive.

The leakage performance of these headphones is outstanding. Even at high volumes, the amount of leakage is quite low, so others around you shouldn't be bothered by your audio if you like to crank it up high.

The recording quality of the Anker Liberty 3 Pro's integrated mic is poor. Your voice sounds full-bodied but thin, dark, and distorted.

The mic's noise handling performance is very good. While the mic lowers the volume of your voice as it reduces background noise, and your voice taps a dip in quality, it's still understandable. If you're taking a call from a busy street, you'll be intelligible.

The Anker Liberty 3 Pro's battery performance is satisfactory. They're advertised to last around eight hours on a single charge, and we measured 5.5 hours, which is a lot less. That said, battery life can vary depending on usage, so your real-world experience may be different. Unlike the Anker Soundcore Liberty 4 True Wireless, their carrying case also holds roughly three additional charges, which is handy in a pinch. They also have an advertised 15-minute quick charge, which is supposed to give three hours of playback time. You can also use one bud while the other one charges and they have an auto-off timer that you can set in their app.

The Anker Liberty 3 Pro have a great companion app with robust features. It offers an 8-band graphic EQ and 20 EQ presets to help you adjust their sound to your liking. This app also allows you to use HearID, which offers personalized noise cancelling depending on in-ear pressure and your environment, or you can select manual mode, which allows you to adjust the amount of noise cancelling. In addition, you can cycle between ANC on, normal, and transparency mode. You can even remap buttons, activate 3D Surround Sound, adjust the auto-off timer, and tweak the tone feedback for controls.
