Soundcore Liberty 4 True Wireless Review: Real User Experience After 3 Months

I have spent the last ninety days with the Soundcore Liberty 4 earbuds glued to my ears. I didn't get these as a reviewer sample; I bought them with my own money because I was tired of the "standard" options and wanted to see if a pair of buds could actually deliver on the promise of high-end audio, health tracking, and top-tier noise canceling without hitting the four-hundred-dollar mark. After three months of daily commuting, office deep-work sessions, and sweaty gym hours, I finally feel like I can give an honest assessment of what it is like to actually live with these things.

The First Impressions and the "Slide" Factor

I remember the day I unboxed these. The first thing I noticed wasn't the earbuds themselves, but the case. Most brands use a flip-top lid that feels like a Zippo lighter. Soundcore went with a sliding mechanism. I’ll be honest: for the first week, I spent more time sliding that lid back and forth than I did listening to music. There is something incredibly satisfying about the smooth, magnetic glide. However, after three months, I have noticed that dust tends to collect in the tracks of that slide. It hasn't jammed yet, but I do find myself needing to wipe out the rails with a Q-tip occasionally to keep that "new" feeling.

When I first put them in, I was struck by the "Stem" design. I've used the original Liberty Air and the Liberty 3 Pro. The 3 Pro was a "bean" shape that felt a bit bulky in my smallish ears. Moving to the Liberty 4, which has a stem more akin to the AirPods Pro, felt like a relief. They are significantly lighter than the 3 Pro, and the weight distribution is much better. In my experience, they don't "tumble" out of the ear when I'm leaning over to tie my shoes, which was a constant fear with the older, heavier models.

The Sound Profile: A Double-Edged Sword

What I found was that the Soundcore signature sound is very much alive here, for better or worse. Out of the box, the Liberty 4 is aggressive. Using the dual dynamic drivers (the ACAA 3.0 system), the bass is punchy—almost too punchy for some of my acoustic tracks. I started my testing with some jazz, and the upright bass felt a bit bloated. However, once I dove into the Soundcore app and ran the HearID test, things changed dramatically.

One thing that bothered me at first was the "sharpness" of the treble. Soundcore has a tendency to tune their highs quite bright. After about two hours of listening to podcasts, I noticed some ear fatigue. I had to go into the custom EQ and pull down the 6kHz and 8kHz sliders by about 3 decibels to make them comfortable for long-term use. If you are someone who likes a "sparkly" sound, you will love these. If you are sensitive to sibilance (that piercing 's' sound in vocals), be prepared to spend some time in the EQ settings.

After testing for several weeks, I grew to appreciate the LDAC support. I use an Android flagship, and being able to stream high-bitrate audio makes a tangible difference in the "space" of the music. When I switched back to a standard AAC connection on my iPad, the soundstage felt noticeably narrower. It’s not a dealbreaker for most, but if you’re paying for a premium streaming service, you’ll be glad the Liberty 4 can actually handle the extra data.

Living with the Heart Rate Sensor

This is the "gimmick" that everyone asks about. The Liberty 4 has a built-in heart rate sensor in the right earbud. I was skeptical. Why do I need my earbuds to tell me my heart rate when I have a dedicated fitness watch? After using it for 90 days, my opinion is mixed. I noticed that the accuracy is surprisingly close to my chest strap when I am sitting still or doing light walking. What I found was that the sensor is highly dependent on getting a perfect seal. If the earbud shifts during a heavy run, the heart rate data starts to spike or drop off entirely.

In my experience, the health tracking is best used for "wellness" rather than "performance." I like that the app tracks my stress levels based on heart rate variability (HRV). I started checking it during my afternoon meetings, and it was eye-opening to see the stress meter climb during particularly tense calls. It’s a nice-to-have feature, but I wouldn't buy these specifically for the health tracking. I look at it as a bonus feature that adds value to the package rather than a core reason to own them.

Noise Cancellation and its Real-World Limits

I’ve used these on three separate flights and countless bus rides over the last three months. The Active Noise Cancellation (ANC) is what I would call "upper-middle class." It’s significantly better than the entry-level buds you find under $100, but it doesn't quite reach the eerie silence of the industry leaders from Sony or Bose. After testing for many hours in a noisy coffee shop, I noticed that the Liberty 4 is excellent at hum and drone: it completely deletes the sound of an air conditioner or a distant jet engine.

However, it struggles with higher frequencies like clinking plates or loud conversations nearby. One thing I appreciated was the "Adaptive" mode. It adjusts the strength of the ANC based on the ambient noise level. I found that it worked seamlessly most of the time, though I did encounter a weird glitch once or twice where the ANC would "pump" or shift levels rapidly when a loud truck drove past me. I usually ended up just locking it to the "Strong" setting manually.

The Transparency mode, on the other hand, is surprisingly natural. One of my biggest gripes with older Soundcore models was that transparency sounded "robotic" and hissed. With the Liberty 4, I can hold a conversation or listen for my train stop without feeling like I'm listening through a cheap microphone. It still isn't quite as "invisible" as the gold standard in the industry, but it’s more than usable for daily life.

The Squeeze Controls: A Welcome Change

I was surprised by how much I ended up liking the squeeze controls on the stems. If you’ve used some other popular brands, you know that tap controls can be hit-or-miss. Sometimes they don't register, or worse, they register an accidental touch when you’re just trying to adjust the bud in your ear. By switching to a physical "squeeze" (you actually press the stem slightly), Soundcore eliminated the ghost-touch issue almost entirely.

I noticed that there is a slight learning curve. You have to find the exact "sweet spot" on the stem. For the first few days, I was squeezing too low or too high and getting no response. Now, it’s muscle memory. I’ve customized my controls so that a single squeeze is play/pause, a double squeeze skips the track, and a triple squeeze toggles ANC modes. Being able to hear a little "click" sound (an artificial tone played in the earbud) when you trigger the squeeze is a small but vital bit of feedback that I missed on my old pair of earbuds.

Spatial Audio: Do You Actually Need It?

Soundcore heavily markets their 360-degree spatial audio with head tracking. In my experience, for music, it’s a bit of a mixed bag. When I listen to classic rock tracks that weren't mixed for spatial audio, the processing feels a bit artificial, like I’m in a large, empty hall. I found myself leaving it off for about 90% of my music listening.

However, for movies? It’s a game-changer. I watched a few action movies on my tablet during a cross-country flight, and the head tracking actually adds a layer of immersion that is quite impressive. When you turn your head to the left, the "center" of the sound stays fixed on the screen. It’s a neat trick that works well for cinema, but I’d advise keeping it off for your daily Spotify playlists to avoid the "reverb" feel.

Battery Life After 3 Months of Wear and Tear

The advertised battery life is about 9 hours for the buds and 28 hours total with the case (with ANC off). In my real-world use with ANC always turned on and LDAC enabled, I’m getting about 5.5 to 6 hours of continuous use before I get the "Battery Low" warning. This is plenty for my needs, but it’s worth noting that if you use all the "high-end" features like heart rate tracking, LDAC, and ANC simultaneously, the battery drain is aggressive.

I haven't noticed any significant degradation in the battery health over these three months. The case still charges quickly, and I love the fact that it supports wireless charging. I just drop it on the pad on my desk at the end of the day. One thing that bothered me slightly is that the earbuds are held in the case by fairly strong magnets, which is good, but the "slick" plastic of the buds can make them slippery to pull out if your fingers are even slightly sweaty after a workout.

Comparison and Analysis

To help you see where these fit in the current market, I've put together a small comparison based on my personal experience with several other leading models I've owned over the past year.

Pros and Cons: The Honest Truth

• Pros:
  • The dual-driver sound quality is remarkably detailed once you tune the EQ to your liking.
  • Multipoint connection is flawless; I can switch from my phone to my laptop without ever touching a menu.
  • The case is one of the most compact and pocketable I have ever used.
  • Squeeze controls are much more reliable than touch controls, especially in the rain or at the gym.
  • The Soundcore app remains the best in the business for customization and firmware updates.
• Cons:
  • The out-of-the-box tuning is very "bright" and can be fatiguing if you don't adjust it.
  • Heart rate tracking is a bit finicky and requires a very specific fit to remain accurate during movement.
  • The "Cloud Comfort" ear tips are soft, but I found I had to size up compared to other brands to get a proper seal.
  • Spatial audio feels like a "processing filter" rather than a true acoustic change for music.

Buying Guide: Is the Liberty 4 Right for You?

After three months of heavy use, I can confidently say these are excellent, but they aren't for everyone. If you are a "set it and forget it" person who doesn't want to open an app, you might find the initial sound profile too harsh. However, if you are a "tweaker"—someone who loves to customize their EQ, adjust their ANC levels, and play with different features—these offer the best value on the market today.

Consider the Liberty 4 if you want a pair of earbuds that can do everything: take calls (the mic quality is actually fantastic, even in wind), survive a gym session, and provide high-fidelity audio for your commute. I have found the "Multipoint" feature alone makes them worth the price. Being able to watch a video on my laptop and have the earbuds automatically switch to my phone when I get a call—and then switch back once I hang up—is a luxury I can no longer live without.

Avoid these if you have extremely sensitive ears and prefer a darker, warmer sound signature like that of some classic hi-fi brands. No matter how much you EQ these, they will always have a bit of that digital "crispness" to them. Also, if heart rate tracking is your only reason for buying, you are better off buying a dedicated fitness tracker and a cheaper pair of earbuds.

A Note on the Design Choices

In my experience, the "Cloud Comfort" tips are a highlight that many people overlook. They are dual-layered, meaning they have a firmer core and a softer outer shell. I noticed that after about four hours, my ears usually start to ache with most buds. With these, I can go the full five-plus hours until the battery dies without that "stuffed ear" feeling. It’s a subtle design choice, but it makes a massive difference for office workers or students who wear their buds all day.

One final thing I noticed was the build quality of the stems themselves. I’ve dropped these on concrete more than once. The plastic is durable and doesn't scuff easily. The "Midnight Black" version I have hides fingerprints well, though my friend’s "Cloud White" pair seems to show earwax and dust a bit more obviously around the sensor area. If you’re a bit messy, stick with the darker colors.

Final Thoughts After 90 Days

If you had asked me on day one if I would recommend the Soundcore Liberty 4, I would have said, "Maybe, let's see how that slider lid holds up." Now, on day ninety, the answer is a definitive yes. Despite the slightly aggressive treble and the somewhat niche health tracking, the core experience—the connectivity, the comfort, and the sheer detail in the audio—is hard to beat at this price point.

I was surprised by how much I relied on the small quality-of-life features. The way the case lights up when you slide it open to show you the charge level, the way the "Fit Test" in the app actually helped me realize I needed a larger tip for my left ear, and the way the microphones handle a breezy walking call without making me sound like I'm in a wind tunnel. These are the things you don't see on a spec sheet, but you notice them every single day you use the product.

The Soundcore Liberty 4 feels like a product made by people who actually use earbuds. It solves the "tap control" frustration, it solves the "bulk" issue of previous models, and it gives you more control than almost any other competitor. It isn't perfect—no piece of tech is—but it has earned a permanent spot in my daily carry. Whether I'm trying to focus in a loud office or just enjoying a long walk, these have been a reliable companion that consistently punches above its weight class.
