AI Verdict
These are 12mm dynamic driver earbuds with 48 hours total playback and IP54 dust/water resistance, for casual listeners wanting adaptable fit and ANC.
These earbuds offer a unique dual-fit design, allowing users to switch between open-ear and sealed-ear tips for comfort or noise isolation. However, the effectiveness of features like ANC is heavily dependent on achieving a proper seal with the in-ear tips.
If a consistent, deep seal for maximum noise cancellation is your top priority, look for earbuds with a dedicated in-ear design and multiple ear tip materials.

Dimension Scores
The 12mm dynamic drivers deliver a bass-heavy JBL Pure Bass sound that many casual listeners enjoy, with clarity in highs and mids preserved.
Adaptive Noise Cancelling is effective when a proper seal is achieved with the included silicone tips, but it's minimal without them.
The ability to switch between open-ear and in-ear fits with included tips provides adaptable comfort for different preferences and use cases.
With up to 8 hours of earbud playtime (ANC on) and 48 hours total with the case, these offer extended listening compared to many competitors.

Watch Out For
- Noise cancellation is significantly less effective without the sealed ear tips, requiring a proper fit for any noticeable reduction in ambient sound.

- Touch controls are restrictive, allowing only two out of three functions (volume, track, or ANC) to be assigned at once.
- Some users experience intermittent music playback, with audio stopping and starting every second.
- The low battery warning is a loud 'BATTERY LOW' announcement, which can be jarring and disruptive.

What Buyers Say
The biggest surprise is how much the noise cancellation depends on the ear tips; without the sealed ones, it's almost nonexistent. Users are split on the Spatial Sound, with some calling it 'shitty reverb' that's not worth using. The app customization for ANC and EQ is a definite plus, but the limited touch control options are a real head-scratcher. Also, that screaming low battery warning is a deal-breaker if you like to doze off with music.
“Man, these things sound pretty good with the bass, but the ANC is a joke unless you jam those silicone tips in, and don't even get me started on that 'BATTERY LOW' shout, almost gave me a heart attack!”
Common Praise
- The 12mm dynamic drivers provide a powerful, bass-forward sound profile.
- The option to use either open-ear or sealed ear tips offers comfort flexibility.
- Battery life is substantial, offering up to 48 hours total playback.
- Call quality is clear due to 6 microphones and environmental noise cancellation.
- The JBL Headphones app provides useful customization for sound and ANC.
- IP54 rating provides resistance against dust and water.
Common Complaints
- Noise cancellation is ineffective without the sealed ear tips.
- Spatial Sound is often perceived as artificial and not enhancing the audio.
- Touch controls are too limited, forcing users to choose between essential functions.
- Intermittent connection issues cause music to stop and start.
- The low battery warning is a loud, disruptive voice prompt.
- The plastic build quality of the case and earbuds doesn't feel premium.
Ownership Tips
- After a few weeks, you'll realize the ANC is only truly effective if you consistently use the sealed ear tips, which might not be your preferred fit.
- You'll probably end up ignoring the Spatial Sound feature because it just adds weird reverb instead of actual immersion.
- The limited touch controls mean you'll be pulling out your phone more often than you'd like to adjust settings.
- The case, while compact, can be a bit fiddly to get the earbuds out of, especially if you have larger fingers.
- The battery life is genuinely long, but the sudden, loud low battery warning can be annoying if you're trying to relax.
Frequently Asked Questions
Do these earbuds have a strong bass response?
Yes, they feature 12mm dynamic drivers and JBL Pure Bass sound, which users describe as bass-enthusiastic and punchy.
How effective is the noise cancellation?
The Adaptive Noise Cancelling works well when using the sealed silicone ear tips, but it's barely noticeable with the open-ear fit. You can adjust the level in the JBL Headphones app.
Can I use these for phone calls in noisy places?
Yes, they have 6 microphones with environmental noise cancellation and echo suppression algorithms designed to capture your voice clearly, even in windy conditions.
What is the total battery life?
You get up to 8 hours of playtime with ANC on, and the charging case provides an additional three full charges, totaling up to 48 hours of playback.
Are they water resistant for workouts?
Yes, they have an IP54 rating, meaning they are dust and water resistant, suitable for workouts or light rain.
Does the Spatial Sound feature actually work?
User opinions vary; some find it enhances immersion, while others describe it as 'shitty reverb' that distorts the sound.
Buying Guide
When you're looking at earbuds, think about how you'll actually use them. Do you need to block out a noisy commute, or do you want to hear your surroundings for safety? The fit is huge – some earbuds seal your ear canal, others sit more openly. This affects both sound quality and how much outside noise gets in. Also, don't just look at total battery life; check the 'earbud only' playtime, as that's what you'll experience between case charges.
Adaptive Noise Cancelling (ANC)
This feature actively listens to outside noise and cancels it out, like having a tiny sound-proof bubble. It's crucial for quiet listening in loud environments like buses or offices, but its effectiveness depends on how well the earbud seals your ear.
12mm Dynamic Drivers
These are the tiny speakers inside the earbuds. A larger driver (like 12mm here) can often move more air, which usually translates to a fuller, more impactful bass response, making your music feel more 'present' and powerful.
IP54 Dust & Water Resistant
This rating tells you how much abuse the earbuds can take from the elements. IP54 means they're protected against dust ingress and splashes of water from any direction, so they'll survive a sweaty workout or a sudden light rain shower without issues.
6 Mics for Perfect Calls
More microphones usually mean better call quality. These earbuds use multiple mics to pick up your voice and simultaneously filter out background noise, so the person on the other end hears you, not the traffic or wind around you.
Alternatives
If you need top-tier noise cancellation, look for models with a dedicated in-ear design and advanced ANC algorithms. For audiophile-grade sound, search for earbuds with support for high-resolution audio codecs and a neutral sound signature.
