Product 2: Nothing Ear (a) Earbuds
4.1

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.

Android compatibility

No score yet
Product 2: Nothing Ear (a) Earbuds
4.4

Android users get extra upside from features like Fast Pair and LDAC, making the Ear (a) a particularly good value outside closed ecosystems.

App
Product 1: H2O Audio TRI 2 PRO...
3.9

The app is useful for firmware, library management, and Playlist+ tasks, but it is basic rather than feature rich and can feel awkward compared with more polished headphone apps.

Product 2: Nothing Ear (a) Earbuds
4.4

Nothing X is widely praised for being clean, stable, and genuinely useful rather than filler software, adding meaningful value to the overall package.

Bass performance
Product 1: H2O Audio TRI 2 PRO...
3.1

Bass is inconsistent. Some reviewers hear solid or even punchier bass, especially underwater or with earplugs, but others call it hollow, woolly, or nearly absent on land.

Product 2: Nothing Ear (a) Earbuds
4.2

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.

Battery
Product 1: H2O Audio TRI 2 PRO...
4.0

Battery life is solid for the category, with most reviews landing around the claimed 9 hours over Bluetooth and 6 hours from memory mode, though some testing suggests real-world endurance can fall short of the marketing numbers.

Product 2: Nothing Ear (a) Earbuds
4.2

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.

Bluetooth
Product 1: H2O Audio TRI 2 PRO...
3.2

Bluetooth is fine for some above-water use, but stability is not flawless. Multiple reviewers mention stutters, disconnects, or pairing friction, and underwater Bluetooth remains impractical as expected.

Product 2: Nothing Ear (a) Earbuds
4.2

Bluetooth stability is mostly solid, but there are scattered reports of stutters in interference-heavy areas, so reliability is good rather than flawless.

Build quality
Product 1: H2O Audio TRI 2 PRO...
4.2

Build quality comes across as sturdy, flexible, and ready for abuse in the pool or during training. The sealed construction and soft exterior inspire confidence.

Product 2: Nothing Ear (a) Earbuds
3.9

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.

Button control usability
Product 1: H2O Audio TRI 2 PRO...
3.4

The controls are the most common complaint. Physical buttons offer tactile feedback, but many reviewers found them too small, too close together, slow on secondary presses, or easy to trigger incorrectly while moving.

Cable quality
Product 1: H2O Audio TRI 2 PRO...
3.0

The magnetic proprietary cable supports the waterproof design, but it adds one more special accessory to keep track of, and one reviewer reported unreliable wired file transfers.

Product 2: Nothing Ear (a) Earbuds
No score yet
Carry case quality
Product 1: H2O Audio TRI 2 PRO...
4.0

The included cases are generally well regarded. Reviewers call them protective and practical, though some found the standard case bulkier than necessary.

Product 2: Nothing Ear (a) Earbuds
4.1

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.

Charging
Product 1: H2O Audio TRI 2 PRO...
4.3

Charging is straightforward once aligned with the magnetic connector, and case-based charging options add convenience, but the waterproof-focused approach means living with a proprietary setup.

Product 2: Nothing Ear (a) Earbuds
3.8

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.

Codec support
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.4

Codec support is strong for the price, covering AAC and SBC broadly while also adding LDAC for higher-quality Android listening.

Comfort during long use
Product 1: H2O Audio TRI 2 PRO...
4.2

Comfort is one of the strongest recurring positives. The open-ear design avoids ear-canal fatigue, vibrations are generally well controlled for the category, and several reviewers found them easy to wear for long swims or runs.

Product 2: Nothing Ear (a) Earbuds
4.6

Long-session comfort is one of the most consistently praised traits, with reviewers repeatedly calling the earbuds easy to wear for hours without fatigue.

Design and Aesthetics
Product 1: H2O Audio TRI 2 PRO...
3.9

The design is sporty and practical rather than stylish. Reviewers like the soft-touch finish and purpose-built form, even if it looks more specialized than everyday headphones.

Product 2: Nothing Ear (a) Earbuds
4.5

Design is a major selling point: the transparent Nothing look feels distinctive, stylish, and far less generic than most earbuds in this price band.

Ear tip size options
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
3.9

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.

Equalizer customization
Product 1: H2O Audio TRI 2 PRO...
1.0

EQ tuning is essentially missing, so you are mostly stuck with the default sound signature.

Product 2: Nothing Ear (a) Earbuds
4.0

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.

Find My
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.1

Find My is a small but appreciated bonus that makes the feature set feel unusually complete for budget earbuds.

Included accessories
Product 1: H2O Audio TRI 2 PRO...
4.2

Accessories are a plus. Earplugs and a protective case show up repeatedly as useful inclusions, and they materially improve the swim experience.

Instrument separation
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.4

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.

LDAC
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.5

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.

Maximum volume clarity
Product 1: H2O Audio TRI 2 PRO...
2.0

Pushing volume too high hurts sound quality. At max levels, reviewers noted distortion, harsher vibrations, and less pleasant listening.

Product 2: Nothing Ear (a) Earbuds

Microphone noise reduction
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.0

Voice isolation can be impressively effective in some tests, yet reviewer consensus is more mixed once wind and heavier background noise enter the picture.

Microphone quality for calls
Product 1: H2O Audio TRI 2 PRO...
2.8

Call quality is usable but not a strength. Voices tend to sound quiet, distant, or light on detail, which fits the swim-first design but limits all-purpose appeal.

Product 2: Nothing Ear (a) Earbuds
4.0

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.

Midrange clarity
Product 1: H2O Audio TRI 2 PRO...
2.9

Mids and vocals are serviceable rather than standout. They come through well enough for workouts and can sound more balanced underwater, but several reviews say voices lose body or detail above water.

Product 2: Nothing Ear (a) Earbuds
4.2

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.

Multi-platform compatibility
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.5

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.

Multipoint connectivity reliability
Product 1: H2O Audio TRI 2 PRO...
1.0

Multipoint support is absent, which limits convenience if you switch between devices often.

Product 2: Nothing Ear (a) Earbuds
4.4

Multipoint is a standout convenience feature here, with most reviews praising smooth two-device switching, though a few noticed occasional prioritization hiccups.

Noise isolation (passive)
Product 1: H2O Audio TRI 2 PRO...
3.2

The open-ear design provides almost no passive isolation on its own. The included earplugs make a noticeable difference in the pool by reducing splash noise and improving perceived clarity and bass.

Product 2: Nothing Ear (a) Earbuds
No score yet
Offline playback and onboard storage
Product 1: H2O Audio TRI 2 PRO...
3.8

The local-memory feature is the reason to buy these. Reviewers like the 8GB storage, drag-and-drop loading, and true phone-free swimming, but Playlist+ is often described as clunky, slow, or awkward, and 8GB trails some rivals.

Product 2: Nothing Ear (a) Earbuds
No score yet
Sensors
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.0

In-ear detection and related sensor-based conveniences add polish, though fit sensitivity can occasionally trigger false pauses until the tips are dialed in.

Software/setup simplicity
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.6

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.

Sound quality
Product 1: H2O Audio TRI 2 PRO...
3.4

Sound quality is the main compromise. Underwater playback is often described as good or at least satisfying for the category, while above-water listening ranges from merely okay to clearly weak compared with better open-ear or in-ear alternatives.

Product 2: Nothing Ear (a) Earbuds
4.4

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.

Soundstage width
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.3

Several reviews describe the presentation as wider and more spacious than expected at this price, helping music and movies feel less boxed in.

Stability
Product 1: H2O Audio TRI 2 PRO...
4.4

Once the fit suits your head, stability is excellent. Reviewers regularly say the headset stays put through swimming, running, and vigorous movement, though smaller heads can end up with extra rear loop.

Product 2: Nothing Ear (a) Earbuds
4.4

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.

Touch control responsiveness
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
4.3

The pinch-based controls are usually described as responsive and more reliable than typical tap controls, although some advanced gestures take practice.

Transparency mode quality
Product 1: H2O Audio TRI 2 PRO...
No score yet
Product 2: Nothing Ear (a) Earbuds
3.7

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.

Treble clarity
Product 1: H2O Audio TRI 2 PRO...
2.8

Treble is acceptable for exercise use, not refined listening. Highs are often described as rolled off, grainy, or slightly distorted when volume climbs.

Product 2: Nothing Ear (a) Earbuds
4.2

Treble detail is generally strong for the class, but some listeners noted the top end is not as airy or extended as pricier earbuds.

Volume output
Product 1: H2O Audio TRI 2 PRO...
3.5

There is enough output for workouts and spoken-word listening, but open-ear use in noisy settings often requires higher volume than ideal.

Product 2: Nothing Ear (a) Earbuds
4.3

Volume output is strong, with enough headroom for outdoor use, though not every reviewer found it exceptionally loud versus the broader market.

Water/sweat resistance rating
Product 1: H2O Audio TRI 2 PRO...
5.0

Water performance is the standout strength. The IPX8 rating and real underwater playback are consistently praised, making these far more convincing for swimmers than most open-ear alternatives.

Product 2: Nothing Ear (a) Earbuds
4.3

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.

Weight comfort
Product 1: H2O Audio TRI 2 PRO...
4.9

These are repeatedly described as lightweight and unobtrusive, which helps during long sessions and makes the headset easy to forget once positioned.
