Anker Soundcore Liberty 4 Pro Earbuds Review

What you're actually getting

The Liberty 4 Pro is Anker's push into premium-adjacent territory without the premium sticker. You're looking at roughly $90 to $130 on Amazon depending on sales, which is the part that makes the rest of this review interesting. At full flagship money it would be a fine pair. At this price it's a steal.

Inside you get adaptive active noise cancelling, a transparency mode, wireless charging, and the LDAC codec for higher-bitrate streaming if your phone supports it. Anker also includes its HearID tuning, which runs a quick hearing test and adjusts the EQ to your ears. Some people swear by it. Others turn it off and live in the app's manual EQ instead, which is genuinely good.

How they sound and how the ANC holds up

The default tuning leans warm and punchy, with bass that has real weight to it. That's a deliberate choice and it works for pop, hip-hop, and most of what people stream on a commute. Treble can get a touch sharp on busy tracks, but the app EQ fixes most of that in about thirty seconds. Audiophiles chasing flat neutral sound aren't the target here, and that's fine.

The noise cancelling is the headline feature and it earns its spot. It flattens low-frequency drone well, which is exactly what you want on a plane or a noisy train. It won't fully erase a coworker two desks over the way Sony's WF-1000XM5 or Bose's QuietComfort Ultra do, but those cost roughly twice as much. For the money, the ANC here punches well above its price.

Battery, fit, and daily living

Battery is a genuine strength. Expect somewhere around 8 to 9 hours per charge with ANC off, and several full recharges from the case, so total runtime lands in the 30-hour range. Wireless charging on the case is a nice touch at this price. A short top-up gives you enough for a commute.

Fit is secure for most ears thanks to multiple tip sizes, and the touch controls are responsive without being twitchy. Call quality is solid in quiet rooms and merely okay in wind or heavy traffic, which is true of almost every earbud in this class. The Soundcore app is one of the better ones out there, with EQ, ANC modes, and control customization that actually make sense.

Who should buy them, who should skip

Buy these if you want strong ANC, big battery, and good sound without spending $250. Commuters, travelers, and anyone who lives in earbuds all day will be happy. The LDAC support is a bonus for Android users with hi-res libraries.

Skip them if you're deep in Apple's world and want AirPods-level handoff and Find My integration, because that experience is just smoother on AirPods Pro. Skip them too if you need the absolute quietest ANC money can buy or studio-flat sound. For everyone else, this is one of the easiest earbud recommendations in the budget-to-midrange bracket.

The verdict

The Soundcore Liberty 4 Pro does the important things well and asks for surprisingly little in return. The ANC and battery are the standouts, the sound is enjoyable with a quick EQ tweak, and the app rounds it out. It's our pick for travel and commuting on a budget, and it'll leave a lot of pricier earbuds wondering why they cost so much more.

Frequently asked questions

Do the Liberty 4 Pro support hi-res audio?

Yes, they support the LDAC codec for higher-bitrate streaming, but only if your phone supports LDAC too, which generally means Android. On iPhone you'll fall back to AAC.

How good is the noise cancelling compared to Sony or Bose?

Very good for the price. It crushes low-frequency drone like engine and train noise. It doesn't fully match the Sony WF-1000XM5 or Bose QuietComfort Ultra on higher-pitched sounds, but those cost roughly double.

What's the battery life really like?

Around 8 to 9 hours per charge with ANC off, and about 30 hours total including the case. The case also supports wireless charging, which is rare at this price.
