ANC is consistently rated as very good for $99: strong enough for commuting, offices, and travel, but still a step below the very best premium earbuds. The ANC controls are a plus, with multiple levels and adaptive behavior giving users more flexibility than many earbuds at this price.
ANC performance is good for the price but not unanimous: several reviews call it strong in Max/Smart modes, while others describe it as average or clearly behind key rivals. Expect solid low-frequency reduction, with more variance on mid/high chatter and wind. Most reviewers note multiple ANC strength options (Mild/Moderate/Max plus Smart/adaptive). Smart can be handy, but lower settings may feel much weaker than Max and the adaptive shifts are not always obvious.
Android users get extra upside from features like Fast Pair and LDAC, making the Ear (a) a particularly good value outside closed ecosystems.
Android support is strong thanks to Fast Pair, broad feature access in HeyMelody, and LHDC availability on compatible phones. Non-OnePlus Android devices may need the app for full control.
Nothing X is widely praised for being clean, stable, and genuinely useful rather than filler software, adding meaningful value to the overall package.
The HeyMelody app (or OnePlus system settings) delivers broad control over modes, EQ, and features. Experiences range from polished and fast to occasionally glitchy, especially when the app fails to detect the buds reliably.
Video lip-sync and general A/V timing are typically good, and low-latency/game modes help in demanding scenarios. Some gaming use can still show slight delay in fast shooters depending on device and settings.
Bass is energetic and satisfying, with enough weight for pop and hip-hop, but the default tuning can lean bass-heavy until you dial it back in the app.
Bass is a defining trait: often described as powerful and punchy, sometimes even thunderous. Whether it is a plus or a minus depends on your taste, and several reviews suggest using EQ/BassWave to moderate it.
Battery life is a clear plus overall, especially with ANC off, and most reviewers found the case and quick top-ups easy to live with day to day.
Real-world battery is usually around 6.5 to 7 hours with ANC on and closer to 10 hours with ANC off, matching most manufacturer claims. Heavy feature stacking (ANC + LHDC + spatial) can noticeably reduce runtime.
Bluetooth stability is mostly solid, but there are scattered reports of stutters in interference-heavy areas, so reliability is good rather than flawless.
Baseline Bluetooth stability is generally solid in everyday use, with rare reports of app-connection hiccups or slower initial pairing rather than persistent dropouts.
General build quality is good enough for the price, but the clear plastics and case finish draw some concern about scratches, creaks, and long-term wear.
Build quality is generally good for the price, with solid fit and finish and durable day-to-day handling. A few reviewers flag that the buds are not especially rugged or that glossy parts show wear like fingerprints.
Control mapping is flexible in the app and most gestures work reliably. A few reviews dislike the lack of pressure-squeeze controls or note that default mappings may require customization to feel complete.
The case is generally liked for its smaller footprint and pocketability, though some reviewers found it fiddly to open, awkward to load, or prone to cosmetic wear.
The case is typically described as compact and pocketable with a decent hinge and finish. A few reviews call the plastic feel less premium or note it can be a bit slippery when removing buds.
Charging is convenient thanks to fast USB-C top-ups, but the missing wireless charging is one of the most repeated compromises in the reviews.
Charging is fast and generally reliable, with quick-charge behavior repeatedly mentioned. The main downside is the lack of wireless charging on the case.
Codec support is strong for the price, covering AAC and SBC broadly while also adding LDAC for higher-quality Android listening.
Codec support is strong for the tier (SBC/AAC plus LHDC 5.0) and generally works well. However, some testing suggests very high LHDC bitrates can be unstable and can cost battery.
Long-session comfort is one of the most consistently praised traits, with reviewers repeatedly calling the earbuds easy to wear for hours without fatigue.
Comfort is a consistent strength: the buds are lightweight and many reviewers report long-session comfort. Fit can feel slightly loose for some ears, so tip selection matters.
Design is a major selling point: the transparent Nothing look feels distinctive, stylish, and far less generic than most earbuds in this price band.
The included tip selection works for most listeners, but the fit options are not especially expansive, so very small ears may need more trial and error.
The box typically includes three tip sizes, which covers most ears but not all; some reviewers wish for extra-large tips or more varied options.
EQ options are helpful and easy to use, but customization depth is limited versus pricier models because the Ear (a) relies on a simpler 3-band approach.
EQ support is a major strength: multiple presets plus a custom multi-band EQ are widely praised for meaningful tuning, though a minority say changes can feel subtle depending on the preset and listening habits.
Find My is a small but appreciated bonus that makes the feature set feel unusually complete for budget earbuds.
Find My features are typically audio-based (playing a sound) rather than full location tracking. Useful for nearby couch-cushion situations, less helpful for true lost-and-gone scenarios.
Frequency response out of the box is commonly described as V-shaped rather than neutral. With the right preset or custom EQ, several reviewers say it can get much closer to balanced listening.
Where instrument separation was discussed, the Ear (a) performed well, making layered parts and small details easier to pick out than expected for budget buds.
Instrument separation is often praised for this class, helped by the dual-driver design and tuning tools. Not every review calls it exceptional, but most agree it is above average at the price.
LDAC support is a real differentiator in this segment and repeatedly mentioned as one reason the Ear (a) feels more premium than its price suggests.
LDAC is not supported; multiple reviews point to LHDC as the hi-res option instead. If you specifically want LDAC, this model is a mismatch.
Clarity at high volume is good overall, though several reviews warn that treble can get harsh or sibilant when pushed toward the top end of the volume range.
Voice isolation can be impressively effective in some tests, yet reviewer consensus is more mixed once wind and heavier background noise enter the picture.
Background-noise handling on calls is frequently praised, with several reviews noting strong suppression of chatter and environmental sounds. Wind handling is good but not universally perfect across all reports.
Call quality is usually clear enough for everyday use, but it is not universally excellent, with some reviews reporting compressed or only average-sounding calls outdoors.
Call quality is often rated very good for the price, with voices coming through clearly. A minority describe it as merely adequate rather than class-leading.
When reviewers called out the mids, they usually praised clear vocals and an open midrange, though the tuning is still more fun than strictly neutral.
Midrange presence is generally decent but can feel recessed compared to the bass and treble in the default tuning. Some reviewers find vocals clear, while others want more natural mid emphasis.
Cross-platform behavior is a quiet strength, with reviewers liking that the core experience works well across Android, iPhone, and PC instead of favoring one ecosystem too heavily.
Cross-platform support is better than many budget buds: iOS users get the app and most core features, but hi-res codec advantages and some behaviors may vary by device ecosystem.
Multipoint is a standout convenience feature here, with most reviews praising smooth two-device switching, though a few noticed occasional prioritization hiccups.
Multipoint is frequently highlighted as a standout convenience feature, with several reviewers calling it excellent or flawless for switching between two devices. Using multipoint can reduce available hi-res bandwidth on some setups.
Preset profiles are generally useful (with some reviewers preferring certain presets as closer to balanced). Bass-leaning presets and BassWave can be fun but may not satisfy listeners chasing a reference curve.
In-ear detection and related sensor-based conveniences add polish, though fit sensitivity can occasionally trigger false pauses until the tips are dialed in.
Wear detection and other sensors generally work as expected for pausing, mode toggles, and personalization tests, though performance can vary by ear fit and configuration.
Glossy or chrome-like surfaces tend to pick up fingerprints and smudges, which multiple reviewers call out. The case finish is often less prone to marks than the earbuds.
Setup and day-to-day software use are repeatedly described as fast, intuitive, and frustration-free, which helps the earbuds feel polished beyond their price.
Setup is usually straightforward with Fast Pair on Android, but a few reviewers report slower pairing or extra friction when installing/using HeyMelody on non-OnePlus phones.
Across the reviews, sound quality is the Ear (a)'s biggest strength: lively, clear, and more refined than most sub-$100 rivals, even if it stops short of true flagship polish.
Overall sound quality is widely considered strong for the price, with an energetic, consumer-friendly tuning and plenty of detail for casual listening. A few reviewers still categorize it as merely good-not-great versus flagship sets.
Several reviews describe the presentation as wider and more spacious than expected at this price, helping music and movies feel less boxed in.
Soundstage is generally moderate with a sense of space that improves with spatial modes, but it is not universally described as wide or holographic in standard stereo playback.
Spatial or 3D audio is polarizing: some reviewers find it immersive and a big value add, while others call it underwhelming or artificial, and it may not behave consistently across apps/devices.
Fit security is usually strong enough for commuting and light workouts, though a few reviewers still had occasional loosening depending on ear shape and activity.
Stability in the ear is good for most users and workouts, but not perfect: a handful of reviews mention needing occasional readjustment, especially with sweat or a looser seal.
The pinch-based controls are usually described as responsive and more reliable than typical tap controls, although some advanced gestures take practice.
Touch and swipe controls are generally responsive and feature-rich (including volume gestures). Some users report occasional mis-taps or finicky behavior when moving or when the touch area is hard to locate.
Transparency mode is usable and sometimes above average for the class, but it is also one of the most common weak spots, especially versus flagship rivals.
Transparency generally sounds natural and usable, but quality varies: some find it close to best-in-class for conversations, while others say it still muffles speech or is not clearly better than ANC.
Treble detail is generally strong for the class, but some listeners noted the top end is not as airy or extended as pricier earbuds.
Treble is usually described as lively and detailed, though it can become sharp, sibilant, or fatiguing at higher volumes for some listeners.
USB-C charging is standard and consistently present across reviews, with no major complaints about the port itself.
Volume output is strong, with enough headroom for outdoor use, though not every reviewer found it exceptionally loud versus the broader market.
Maximum loudness is a frequent positive: many reviewers note it gets very loud without needing to push the volume far. This helps in noisy environments but can tempt unsafe listening levels.
The buds are seen as gym- and commute-friendly thanks to their splash resistance, but the lower-rated case means the protection is not equally robust everywhere.
The IP55 dust and water rating is a meaningful plus for rain and sweat, and reviewers generally treat it as dependable for everyday exercise. It is not intended for submersion.
