Anker Soundcore Liberty 3 Pro Review: Audiophile Sound for Runners, With Caveats

Introduction

The Anker Soundcore Liberty 3 Pro are true wireless earbuds with a clear emphasis on sound quality, pitched at listeners who also want something they can run in. Priced at £139.99 (or $169.99), they combine a dual-driver design, personalized active noise cancellation, IPX4 sweat resistance and around 30 hours of total battery life. After extended testing on easy runs, long runs, commutes and even races, the picture is mixed in an interesting way: the sound is genuinely impressive, while the fit and controls demand more effort than most sports earbuds.

Who This Product Is For

These earbuds suit listeners who care most about audio quality but still want to use them for fitness. They are not the most compact running earbuds on the market, and they are not the most straightforward to set up. If your priority is a secure race-day fit with instantly responsive controls, other options may serve you better. But if you want big, powerful sound from a pair of buds you can also take out on easy and steady runs, they deserve a place on your shortlist.

Fit and Comfort

Fit outcomes here depend heavily on patience. The Liberty 3 Pro use a customizable fusion comfort fit design combining four ear tip sizes and four ear wing sizes, and you really do need to experiment to find the right combination. One tester found the fit spot on after spending time with the tips, wearing them for a full month across races, easy miles and long hot runs without a single fall-out, rating them above previously favored sports buds. Another found the fit good for steady and slow runs but hesitant to trust them at faster paces or in races.

They sit slightly larger in the ear than dedicated sports earbuds, which Anker addresses with a triple-point design meant to reduce pressure over long listening sessions. That approach works: both testers could wear them for extended periods without discomfort.

Controls and App

The touch controls are the weakest link. They respond to taps and swipes for skipping tracks, changing modes and adjusting volume, but while on the move they proved slow to respond, occasionally queuing up multiple inputs and misfiring. Runners with sweaty hands will recognize the frustration: tapping at pace is unreliable, and an accidental extra press while listening to a podcast can skip an entire episode. There is also no obvious logic to the default gestures, so one tester spent a solid 15 minutes with the manual and the app before the controls felt usable.

Here is the fair counterpoint: once that setup investment is made, the controls work well. After customizing the gestures in the Soundcore app, the same skeptical tester reported very few mis-presses and could operate them easily. If you are willing to put in the time, the controls go from a dealbreaker to merely a hurdle.

Case and Charging

The case is not the smallest available, but it slides open easily and fits in a running belt without trouble. Inside you get USB-C charging, a pairing button and notification lights for battery and charge levels, plus wireless charging support. The smooth finish polarized opinion: one tester liked the sliding motion, while another disliked how slippery it is, noting smooth cases can slip out of pockets. One recurring niggle: occasionally a bud would not snap fully into its magnetic slot and would fail to charge, so it is worth confirming both buds are seated properly each time.

Sound Performance

This is the headline. The Liberty 3 Pro use a 10.6mm dual-driver setup, including an ACAA II coaxial dual driver, delivering powerful, bass-forward sound with a wide sound stage. For up-tempo genres like drum and bass and electronic music, they excel, and podcasts also sound fantastic.

Compared with running-specific earbuds, which typically trade sound quality for IP ratings and secure fits, the Liberty 3 Pro offer sound that is genuinely competitive and better than many sports earbuds. The trade-off is slightly less refined treble; cheaper running buds can sound more balanced at the top end. ANC performance is solid, roughly on par with other mainstream sports earbuds, though it will not drown out wind in blustery conditions and does not reach the standard of premium flagship buds.

The app adds heavy personalization: a personalized ANC feature that tests the buds in your ears and tailors noise cancellation and sound to your hearing and preferences, plus a wide range of EQ presets. The real-world benefit of the personalization is debatable, but the sheer number of sound customization options is generous.

Battery Life and Connectivity

Battery life matches the claims. You get 8 hours per bud with an additional 24 hours from the case, roughly 32 hours total, and the figure held up across a month of running and commuting. With ANC on, an hour of running cost around 10 to 15 percent of battery; switching ANC off extends that. The 15-minute quick charge adds about 3 hours of listening time, which covers forgotten charges before a run.

Connectivity needed an awkward start. Initial pairing required several unpair-and-repair cycles, but after that the buds connected instantly with a Pixel 6 Pro as soon as the case opened. One quirk remains: roughly once per hour of listening, the audio cuts out briefly for a couple of seconds before returning. It is minor but unfixable and worth knowing about.

Buying Advice

At around £140, the Liberty 3 Pro are hard to call a clear win against the competition. The Jabra Elite 4 Active, at around £120, offer a more secure and comfortable fit, good sound, strong battery life and no wing tips or ear gels to fiddle with, making them the safer pick for most runners. The JBL Reflect Flow Pro, around £100, deliver great sound too, though they are even chunkier. If the Soundcore dropped to roughly £110 to £115, it would be a steal for audio-focused buyers; at its current price, the sound is excellent but not quite enough to outweigh the fit and control compromises.

Conclusion

The Anker Soundcore Liberty 3 Pro are earbuds for people who put sound first and running second. The audio is among the best at this price, battery life is accurate and reliable, and the comfort can be excellent once dialed in. The touch controls take real effort to tame, the fit is trustworthy for steady runs but questionable for racing, and the price is a touch high. If you are an audiophile who likes doing fitness and can find them discounted, they are a rewarding pick; if you want a fuss-free running companion, look elsewhere.
