AI Verdict
These are 50dB ANC earbuds with 11mm bass drivers and LDAC, offering 43 hours of playtime for users prioritizing deep bass and long battery life on a budget.
These earbuds are a situational fit because while they offer strong 50dB hybrid ANC and 43 hours of battery life, their default bass-heavy sound and less effective high-frequency noise cancellation might not suit everyone. The unique Smart Dial is a cool feature but can be a hassle if you're not careful with how you carry the case.
If you need more balanced audio or superior high-frequency noise cancellation, look for earbuds with a flatter frequency response or higher-rated ANC specifically for a broader range of sounds.

Pros
- LDAC lossless transmission delivers high-resolution audio with compatible devices.
- 50dB Adaptive Hybrid ANC effectively reduces lower frequency environmental noise.
- Total battery life of 43 hours with the fast charging case, and 11 hours per earbud.
- Dual drivers, featuring an 11mm ultra bass driver and a 6mm tweeter, provide distinct audio separation.
- The Smart Dial on the case offers customizable controls for volume, tracks, and noise modes.
- IP55 waterproof design provides dust and water resistance for active use.
Cons
- The default sound profile is heavily bass-focused, which may require EQ adjustment for a balanced sound.
- The Smart Dial on the case can accidentally turn in pockets, leading to unintended volume changes or mode switches.
- ANC is less effective at canceling out high-frequency sounds, which can feel amplified.
- Some users report the right earbud stops charging past 75-85% after a few months of use.
- Transparency mode can sound slightly muffled, making conversations less natural than with premium alternatives.
Dimension Scores
The dual drivers (11mm bass, 6mm tweeter) and LDAC support deliver rich, high-resolution audio, though the default bass is very prominent.
The 50dB Adaptive Hybrid ANC is effective for lower frequencies but struggles to block out higher-pitched environmental sounds.
While many find them comfortable, some users report fit issues that can lead to unreliable in-ear detection and accidental pauses.
With 11 hours of playtime per earbud and 43 hours total with the case, plus fast charging, the battery life is above average.
Best For
- Budget-conscious users seeking strong low-frequency noise cancellation.
- Listeners who prefer a powerful, bass-heavy audio experience.
- Commuters or travelers needing extended battery life for long journeys.
- Mobile gamers benefiting from 120ms low latency with Nothing phones.
Not Recommended For
- Audiophiles who prioritize a neutral and analytical sound signature.
- Users requiring top-tier active noise cancellation for high-pitched sounds.
- Individuals who frequently carry their earbuds loosely in a pocket.
Watch Out For
- The Smart Dial on the charging case is prone to accidental rotations when carried in a pocket, leading to unexpected volume changes or setting adjustments.
- Multiple users have reported an issue where one earbud, often the right one, stops charging beyond 75-85% capacity after several months of ownership.
- The matte material of the charging case scratches and gets dirty very easily and quickly, showing dark abrasions after a few days of use.
- Static noise can sometimes appear briefly when switching between normal, outdoor, or noise cancellation modes.
- In-ear detection can be unreliable, causing music to randomly pause or resume without the earbuds being removed or inserted.

What Buyers Say
Many users are surprised by the value these earbuds offer for their price, especially the inclusion of LDAC and 50dB ANC. The sound is often described as bass-heavy out of the box, which can be adjusted via the Nothing X app. The Smart Dial on the case is a polarizing feature; some love the unique control, while others find it prone to accidental activation in a pocket.
“Dude, these things sound wild for the money, but my right earbud only charges to 80% now and the case looks like it fought a badger after two weeks. Still, the bass slaps.”
Common Praise
- The sound quality is surprisingly good for the price, especially with LDAC enabled.
- The 50dB ANC effectively cancels out low-frequency background noise.
- The Nothing X app provides a robust and user-friendly interface for customization, including EQ.
- The Smart Dial on the case is a unique and satisfying way to control playback and settings.
- Battery life is long, with 11 hours per charge and 43 hours total with the case.
- Dual connection allows seamless switching between two devices.
Common Complaints
- The default sound profile is too bass-heavy for some listeners.
- The Smart Dial on the case can be accidentally triggered in a pocket.
- ANC is less effective against high-frequency sounds, making them noticeable or even amplified.
- Some users experience a specific issue where one earbud stops charging fully (e.g., only to 75-85%).
- The case material scratches and shows wear very quickly.
- Transparency mode can sound muffled, making it difficult to hear surroundings clearly.
Ownership Tips
- The charging case's matte finish is prone to visible scratches and dirt accumulation after minimal use.
- The Smart Dial on the case requires conscious locking or careful placement to prevent accidental adjustments in transit.
- Some users have reported a degradation in earbud charging capacity over several months, with one bud failing to reach 100%.
- In-ear detection can be inconsistent, leading to unexpected pauses or playback.
- The notification sound for Smart Dial adjustments can be disproportionately loud compared to the actual media volume.
Frequently Asked Questions
How effective is the noise cancellation?
The earbuds offer 50dB Adaptive Hybrid ANC, which is effective at reducing lower frequency noises like engine hum. However, it struggles more with high-pitched sounds, which some users report can feel amplified.
What does the Smart Dial do, and is it useful?
The Smart Dial on the charging case allows you to customize controls for volume, track skipping, and noise modes. It's a unique feature for quick adjustments, but it can accidentally turn in your pocket, leading to unintended changes.
What is the battery life like?
You get up to 11 hours of playtime per earbud, and a total of 43 hours with the fast-charging case. A 10-minute charge provides 3 hours of playback.
How is the call quality?
Equipped with 6 HD audio microphones and Clear Voice Technology 3.0, the call quality is generally decent, with good wind noise reduction for clearer communication.
Buying Guide
When you're looking at wireless earbuds, you need to think about how they'll fit into your daily grind. Active Noise Cancellation (ANC) isn't just about blocking out sound; it's about what *kind* of sound. Some ANC is great for airplane hum, but won't touch a crying baby. Driver size and type tell you a lot about the sound profile – bigger bass drivers usually mean more thump. And battery life? That's your freedom from charging cables. Don't forget about codecs like LDAC if you care about getting the best audio quality your phone can send.
50dB Adaptive Hybrid ANC
This isn't just a fancy number; it means the earbuds can actively listen to your environment and create an 'anti-noise' signal to cancel out sounds, especially lower frequencies. 50dB is a significant reduction, making your commute quieter, but it won't mute everything.
11mm Bass with LDAC
The 11mm bass driver is responsible for the deep, punchy low-end sound, giving your music a lot of impact. LDAC is a high-resolution audio codec, which means if your phone supports it, you're getting a much more detailed and 'lossless' audio stream, closer to studio quality than standard Bluetooth.
43H Playtime
This is the total listening time you get before needing to plug in the case. It combines the battery life of the earbuds themselves (11 hours) with the extra charges stored in the case. It means you can go for days without worrying about finding an outlet.
Smart Dial
This is a physical rotating dial on the charging case, letting you adjust volume, skip tracks, or change ANC modes without touching the earbuds or your phone. It's like having a dedicated remote, but it's on the case itself.
Alternatives
If these don't hit right, look for earbuds emphasizing a 'neutral' or 'balanced' sound profile if you're not a bass-head, or check reviews specifically mentioning strong ANC performance against high-frequency noises. Consider models with touch controls directly on the buds if a case dial isn't your thing.
