Average score
H2O Audio TRI 2 PRO Headphones
3.6
Equalizer customization
H2O Audio TRI 2 PRO Headphones
1.0
EQ customization is essentially absent, with reviewers explicitly noting no EQ or presets to tune the sound.
Shokz OpenFit 2+
4.2
EQ customization was a clear strength: reviewers liked tweaking sound, custom EQ, and personal preference controls, though one app workflow was limited.
Instrument separation
H2O Audio TRI 2 PRO Headphones
1.8
Instrument separation is weak in critical listening, with strings, guitar, and bass parts getting lost or failing to cut through the mix.
Shokz OpenFit 2+
4.7
Instrument separation was praised when reviewers heard clean, distinct instruments or stereo separation without muddying vocals and guitars.
Maximum volume clarity
H2O Audio TRI 2 PRO Headphones
2.0
Maximum-volume playback is a recurring weakness, with distortion, muddiness, overpowering tracks, or bone-conduction tickle appearing at louder levels.
Shokz OpenFit 2+
4.5
Most reviewers who discussed high-volume behavior heard clean playback without distortion, though one warned that very high volume could sound cranky.
Noise isolation (passive)
H2O Audio TRI 2 PRO Headphones
3.8
Passive isolation depends on the open-ear tradeoff: awareness is strong, but external noise can drown out playback unless earplugs are used.
Shokz OpenFit 2+
1.5
Passive isolation is essentially not the point of the design; the cited reviewer emphasized that the earbuds do not isolate the listener from the world.
Microphone quality for calls
H2O Audio TRI 2 PRO Headphones
2.3
Call quality is a weak point overall; some calls are usable, but several reviewers report quiet, distant, or incomplete microphone pickup.
Shokz OpenFit 2+
4.2
Call quality was mostly praised as clean, clear, or very good, with caveats around wind, crowded cafés, or heavy processing.
Button control usability
H2O Audio TRI 2 PRO Headphones
3.0
Controls are divisive: some reviewers found them reachable or simple, while many criticized stiff buttons, accidental presses, and unreliable secondary commands.
Shokz OpenFit 2+
4.5
Physical buttons were widely praised as easier, more reliable, and more comfortable than touch-only controls, though one ultrarunner wanted an on/off button.
Portability/foldability
H2O Audio TRI 2 PRO Headphones
4.0
Portability is supported by a compact, gym-bag-friendly case in the review that discussed it.
Shokz OpenFit 2+
2.5
Portability had one notable criticism from an ultrarunner who found carrying the case extra weight and space during long races.
App
H2O Audio TRI 2 PRO Headphones
2.9
The app is adequate but limited; some found it easy to navigate, while others wanted clearer instructions, more customization, or smoother access to stored music.
Shokz OpenFit 2+
4.3
The app was generally considered useful, simple, or feature-rich for EQ, firmware, controls, Dolby, and tracking, though a few reviews described it as minimal or not essential.
Treble clarity
H2O Audio TRI 2 PRO Headphones
3.0
Treble is serviceable but not consistently crisp; reviewers mention rolled-off, grainy, or missing high-end detail, with a few brighter elements coming through well.
Shokz OpenFit 2+
4.4
Treble drew mostly positive comments for crispness, sparkle, and detail, while SoundGuys found the treble weak and less detailed in busy mixes.
Midrange clarity
H2O Audio TRI 2 PRO Headphones
3.1
Midrange and vocals range from clear and full in some testing to static, under-defined, or not very cutting in more critical reviews.
Shokz OpenFit 2+
4.3
Midrange and vocals were generally described as clean, natural, energetic, or more forward, with the strongest praise coming from music-focused reviews.
Bass performance
H2O Audio TRI 2 PRO Headphones
3.0
Bass is highly inconsistent: some reviews praise punch or improved bass in water, while others say land playback lacks low-end impact or becomes woolly and hollow.
Shokz OpenFit 2+
4.2
Bass was often better than expected for open-ear earbuds, especially with EQ or Dolby, but several reviewers still noted limited punch and depth compared with sealed earbuds.
Software/setup simplicity
H2O Audio TRI 2 PRO Headphones
3.1
Setup is mixed: drag-and-drop loading can be easy, but Playlist+, app handling, and troubleshooting are often described as clumsy or time-consuming.
Shokz OpenFit 2+
4.3
Setup simplicity was supported by the convenient pairing button and the fact that app use is not required for basic functions.
Sound quality
H2O Audio TRI 2 PRO Headphones
3.5
Reviewer opinion is split by use case: underwater and swim use often sounds good or even impressive, while several reviewers criticize above-water sound as tinny, muddy, or below regular earbuds.
Shokz OpenFit 2+
4.5
Reviewers broadly praised the open-ear sound as unusually strong, clear, balanced, or top-tier for the category, though SoundGuys treated it as below critical-listening earbuds and one runner focused mainly on clear voice playback.
Battery
H2O Audio TRI 2 PRO Headphones
4.0
Battery life is mostly good for workouts and swims, though one review found real-world drain below the stated claim.
Shokz OpenFit 2+
5.0
Battery life received strong agreement as excellent, long-lasting, or a non-issue for daily use, training, and long sessions.
Value for money
H2O Audio TRI 2 PRO Headphones
3.5
Value depends heavily on the use case: swimmers often get enough benefit, while land users and audio-focused buyers face better-value alternatives.
Shokz OpenFit 2+
4.5
Value was usually positive for first-time buyers because reviewers saw the $10-$20 Plus premium or category price as justified, though existing OpenFit 2 owners may not need to upgrade.
Volume output
H2O Audio TRI 2 PRO Headphones
3.0
Volume is adequate for some voices and workouts, but multiple reviewers had to raise it high, noticed vibration, or found volume changes distracting in water.
Shokz OpenFit 2+
4.0
Volume was usually enough for music, calls, and outdoor use, but reviewers split on headroom in noisy places, with some wanting more output.
Design and Aesthetics
H2O Audio TRI 2 PRO Headphones
3.8
Design works well for aquatic use and looks clean to some reviewers, but fit gaps and sizing for smaller heads create caveats.
Shokz OpenFit 2+
4.8
Design and aesthetics were praised as classy, understated, premium, sleek, and among the best-looking open-ear designs tested.
Carry case quality
H2O Audio TRI 2 PRO Headphones
4.1
Case quality is mostly praised as nice, protective, or convenient, though one reviewer found the standard case bulky.
Shokz OpenFit 2+
3.3
Case quality was mixed: reviewers liked the size/design and wireless charging, but cited a pinch hazard, poor low-battery signaling, and non-waterproof case limitations.
Comfort during long use
H2O Audio TRI 2 PRO Headphones
4.1
Comfort is generally strong thanks to low weight and soft contact, though a few reviewers report long-wear soreness or fit quirks.
Shokz OpenFit 2+
4.9
Comfort was one of the strongest points across nearly every review, with repeated praise for long-wear softness, low fatigue, and all-day active use.
Sound leakage
H2O Audio TRI 2 PRO Headphones
3.5
Sound leakage is mixed: pool use appears discreet, but above-water leakage can appear at higher volumes.
Shokz OpenFit 2+
4.3
Sound leakage was generally better than expected for open-ear earbuds at reasonable volumes, but reviewers still warned that higher volumes can be heard nearby.
Water/sweat resistance rating
H2O Audio TRI 2 PRO Headphones
4.9
Water readiness is the strongest consensus area, with reviewers repeatedly praising pool, underwater, and waterproof performance.
Shokz OpenFit 2+
4.3
Water and sweat resistance was generally reassuring for rain, sweat, and workouts, though reviewers warned against submersion and sweat-related charging care.

Shokz OpenFit 2+

Shokz OpenFit 2+
2.0
Only SoundGuys offered an opinionated frequency-response critique, finding upper mids and treble below its preferred target.

Shokz OpenFit 2+
5.0
Multi-platform compatibility was positively supported by tested compatibility across Android and iOS.
Bluetooth
H2O Audio TRI 2 PRO Headphones
2.9
Bluetooth experiences vary sharply: pairing can be easy on phones and laptops, but underwater use, stutters, random disconnections, and clumsy setup hurt reliability.
Shokz OpenFit 2+
3.3
Bluetooth behavior was mixed: reviewers liked seamless single-bud use, but others reported earbuds staying connected in the case or draining phone battery without an off switch.
Build quality
H2O Audio TRI 2 PRO Headphones
4.4

Shokz OpenFit 2+
4.8
Build quality was praised through flexible/durable ear hooks and robust-feeling materials.
Charging
H2O Audio TRI 2 PRO Headphones
4.2
Charging feedback is positive where reviewed, with magnetic connection clarity and roughly one-to-two-hour charging times.
Shokz OpenFit 2+
4.5
Charging was praised for wireless convenience and quick top-ups, but one review reported case charging behavior that could leave earbuds undercharged.
Stability
H2O Audio TRI 2 PRO Headphones
4.3
Stability is a major strength in water and workouts, although one reviewer with fit issues felt less secure while running.
Shokz OpenFit 2+

Stability was strong for running, workouts, and general movement, but reviewers found caveats with helmets, buffs, high-impact jumps, or losing an earbud when removing layers.

H2O Audio TRI 2 PRO Headphones
4.7
Weight comfort is a clear strength; reviewers repeatedly call the headset lightweight enough for running, swimming, and extended workout use.
Shokz OpenFit 2+
4.8
Weight comfort was consistently praised; reviewers repeatedly said the earbuds felt very light or nearly disappeared on-ear.
Active noise cancellation
H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+
1.3
Reviewers consistently framed ANC as absent or unsuitable for noise-cancellation seekers, treating the product as intentionally awareness-first instead.
Audio-video sync accuracy
H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+
4.0
One reviewer found video latency minimal and acceptable for casual gaming, while noting no dedicated gaming mode elsewhere in the review.
Cable quality
H2O Audio TRI 2 PRO Headphones
2.7
Charging and transfer cable feedback is mixed, from necessary for waterproofing to inconvenient proprietary limitations and one failed USB loading experience.
Shokz OpenFit 2+No score yet
Clamping force comfort
H2O Audio TRI 2 PRO HeadphonesNo score yet

The one explicit clamping-force assessment was very positive because the reviewer felt no clamping pressure at all.
Codec support
H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+

H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+

Headband adjustability
H2O Audio TRI 2 PRO Headphones
2.5
Adjustability is limited, with one reviewer wishing the band could be adjusted for a looser fit.
Shokz OpenFit 2+No score yet
Included accessories
H2O Audio TRI 2 PRO Headphones

Shokz OpenFit 2+No score yet

H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+

Microphone noise reduction
H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+

Offline playback and onboard storage
H2O Audio TRI 2 PRO Headphones

Soundstage width
H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+

Spatial audio
H2O Audio TRI 2 PRO HeadphonesNo score yet
Shokz OpenFit 2+
4.1
