The Anker Soundcore Liberty 4 True Wireless are wallet-friendly in-ears. Like the Anker Soundcore Space A40 Truly Wireless, they support multi-device pairing and LDAC, which is Sony's proprietary codec for Hi-Res audio. They also can access Anker's Spatial Audio feature, which offers speaker modeling and head tracking to help create a more immersive audio experience and have a built-in heart-rate sensor you can then monitor in the app. On the downside, our unit's L/R drivers are mismatched, skewing audio to the right.
Our Verdict
The Anker Soundcore Liberty 4 are mediocre for neutral sound. Out of the box, they have a very bright sound profile, which is a bit piercing and painful. They have extra bass, but to balance out the rest of their sound profile, Anker also boosted their high-mid to treble range. Unfortunately, this results in harsh vocals and instruments while sibilants like cymbals are piercing. Luckily, you can finetune their sound to your liking using their companion app's graphic EQ and presets. The app also offers a spatial audio feature, which allows the headphones to track your head movements for a more immersive experience.
- Graphic EQ and presets available in companion app.
- Bad passive soundstage.
The Anker Soundcore Liberty 4 are decent for commute and travel. These buds are comfortable, well-built, and lightweight. They're also small enough to fit into most bags or cases without an issue. That said, even though they have an adaptive ANC system, they struggle to block out the low rumble of bus engines. Their over six-hour continuous battery life may not last through long trips, but their carrying case has an additional two charges.
- Stable, comfortable, and well-built.
- Struggles to block out the low rumble of bus engines.
The Anker Soundcore Liberty 4 are great for sports and fitness. They have a comfortable and well-built fit that's certified IPX4 for resistance against splashes of water. They also have a built-in heart-rate monitor and you can use the app to track it. Even though they don't have stability fins, once you get a good fit, they should stay in place during moderate activities like a jog in the park. Unfortunately, the buds can pop out of your ears while you're chewing or talking, which is a bit annoying.
- Stable, comfortable, and well-built.
- IPX4 for water resistance.
- Bad passive soundstage.
The Anker Soundcore Liberty 4 are fair for office use. These buds have a comfortable fit suitable for long days at the office and their ANC system can tackle ambient sound like coworkers chatting around you. They also support multi-device pairing, so you can connect the buds to your phone and PC simultaneously. While they last over six hours and may need a top-up throughout the workday, their carrying case holds two extra charges if you need it.
- Supports multi-device pairing.
- Stable, comfortable, and well-built.
- Bad passive soundstage.
- Mic has mediocre recording quality.

The Anker Soundcore Liberty 4 are alright for phone calls. They have an integrated mic that does a mediocre job of capturing your voice clearly.

These buds also have an ANC system that can help block out a fair amount of ambient noise.
- Supports multi-device pairing.
- Mic has mediocre recording quality.
