Compare JBL Endurance Race 2 Earbuds vs Bose QuietComfort Ultra Earbuds (2nd Gen)

ANC is useful for taking the edge off treadmills, office chatter, and travel noise, but every detailed reviewer said it falls clearly short of premium earbuds. ANC and ambient tuning are adjustable in the app, but reviewers generally felt those sliders and sport-mode tweaks made only modest real-world differences.

Noise cancelling is repeatedly described as class-leading, with especially strong suppression of engine rumble and broad-spectrum everyday noise; a few reviews note minor hiss or occasional artifacts with sudden loud impacts, but overall performance remains top tier. Adjustability is strong via app modes and sliders, including custom levels and adaptive behavior (such as smoothing spikes), though some mode limitations and UI quirks are mentioned.

Android support looks solid thanks to Google Fast Pair support and no reported compatibility red flags, though direct Android testing was limited.

Android support is repeatedly framed as a strong use case, with modern Bluetooth features and higher-quality codec options that cater well to Android ecosystems.

The JBL app adds meaningful tuning options, sports modes, and control customization, but several reviewers found some mode behavior inconvenient or not especially impactful.

The Bose app is generally seen as essential and functional for modes, device management, and settings, though some workflows (like mode creation) can feel limited or slightly confusing.

aptX Adaptive (including higher-quality variants cited by reviewers) is a key advantage versus some rivals for Android listeners who want better Bluetooth audio performance when supported by their phone.

Audio/video sync is usually fine for casual viewing and even editing for some users, but multiple comments suggest latency is not ideal for competitive gaming or fast-reaction play.

Bass is decent and workout-friendly, but multiple reviews suggest it benefits from EQ boosting rather than sounding especially punchy on the default tuning.

Bass is consistently described as deep, punchy, and satisfying; some listeners consider it aggressive or dominant, especially out of the box.

Battery life is a standout strength, with reviewers consistently praising the long single-charge runtime and strong total endurance with the case.

Battery life is consistently called average for the category: typically around 6 hours with ANC, dropping with immersive/spatial modes, and supported by multiple case recharges.

Connection stability was excellent in testing, with easy room-range use during workouts and no reported dropouts.

Bluetooth stability is generally reported as solid across iOS and Android devices, with few or no dropouts in typical use, though some reviewers mention earlier-gen complaints and suggest toggling certain features if problems appear.

Earbud build quality is generally considered premium, with durability expectations aligned to the price; the case gets more mixed feedback on feel and refinement.

Controls are easy to learn and include useful gestures (notably swipe volume), yet multiple reviews mention finickiness and accidental activations; the ability to disable touch controls is an important mitigation.

The case is functional but not a highlight: it is on the larger side, only lightly protected against moisture, and can pick up wear in a gym bag.

The case is frequently described as bulky and less premium-feeling than the earbuds themselves; some reviewers also note the buds can be awkward to retrieve.

Charging performance is strong, with quick-charge support and reasonable full-charge times repeatedly called out as practical positives.

Charging is a Gen 2 strong point thanks to wireless charging support, plus fast top-ups via the case; a few notes suggest wireless coil placement can be finicky on some pads.

Codec support is a highlight for many reviewers, especially for Android users, with modern high-quality options noted alongside broad device compatibility.

Long-session comfort is unusually good for winged sports buds, with reviewers noting they stayed comfortable through runs, workouts, and daily use.

Comfort is widely praised for long sessions, especially once tips and stability bands are dialed in; a consistent caveat is that the shell size may not suit the smallest ears.

The design is sporty and available in appealing colors, but the buds are still noticeably chunky and protrude more than slimmer everyday earbuds.

Design is polarizing: many like the sleek, modern look, but the buds are visually and physically large, which can be a problem for smaller ears.

The included three ear-tip sizes were a useful fit aid, though one reviewer still felt the overall shell size may be too large for smaller ears.

Tip and wing options are helpful for achieving a strong seal, but multiple reviews note the included range is adequate rather than expansive given the premium price.

EQ customization is a real plus, letting users add extra bass or adjust the sound for workouts without needing third-party tools.

EQ customization is a frequent criticism: it is typically described as a basic 3-band tool with limited precision, which may frustrate listeners trying to meaningfully reshape the tuning.

One reviewer explicitly noted that there is no Find My-style locating feature, which limits convenience compared with some rivals.

Accessory support is good for the class, with extra ear tips, wing options or covers, and a charging cable included in the box.

Accessories commonly include multiple tip sizes and stability bands plus a charging cable; a few reviewers wish for extras like more sizes or a longer cable.

Instrument separation is repeatedly rated as strong, helping busy tracks stay organized and making details easier to pick out.

The earbuds include an onboard multi-mic setup that works well enough for routine calls and general hands-free use.

At higher volumes, clarity drops off and upper-range detail compresses, so these do not stay especially clean when pushed hard.

At higher volumes, clarity generally holds up well according to multiple impressions, though overall tonal preference still depends on how you feel about the bass-forward tuning.

Call noise handling is respectable rather than exceptional, keeping traffic and background noise fairly controlled without fully erasing it.

Noise reduction for calls is frequently praised (including AI-style voice isolation), yet a minority of measurements-based reviews report that wind and background sound can still bleed through depending on scenario.

Call quality is generally clear and usable, though voices can sound slightly hollow instead of especially rich or natural.

Call quality is widely reported as improved versus earlier generations, often sounding clear and intelligible; however, some tests still find it can struggle in very windy or extremely noisy environments.

Midrange performance is one of the stronger parts of the tuning, with vocals and core musical content coming through clearly for the price.

Midrange presentation is generally clear enough for vocals and instruments, but opinions vary: some hear warmth and natural tone while others cite recessed or uneven mids that can affect certain voices.

Compatibility looks broad, with successful use across phones, laptops, watches, and support for both Google and Microsoft quick-pair systems.

Cross-platform use is broadly positive across phones, tablets, and computers; iOS works well, though several reviewers still note Apple ecosystem extras remain a separate advantage for AirPods users.

Multipoint was a meaningful win, with seamless switching between devices highlighted as one of the more premium-feeling features at this price.

Multipoint is a meaningful quality-of-life feature and is mostly described as seamless for switching between two devices, with occasional notes that pausing one stream before starting another helps.

No summary yet.

Portability is only average because both the buds and especially the case are a bit bulky compared with more pocket-friendly alternatives.

Portability is mixed: the case is pocketable but noticeably larger than key competitors, and runners often find it inconvenient to carry during workouts.

The preset sports profiles are more interesting on paper than in practice, with reviewers often describing them as gimmicky or only mildly different.

Preset EQ profiles are described as basic and not always effective at fixing core tuning preferences, especially for listeners sensitive to boosted bass or treble.

In-ear detection and related sensors are supported and configurable; at least one review suggests turning detection off if it contributes to unwanted playback behavior or stutters in edge cases.

Setup is straightforward, with easy pairing and uncomplicated day-one use standing out as low-friction strengths.

Setup is usually straightforward, but several reviews emphasize the app is effectively mandatory for fully managing features like multipoint, modes, shortcuts, and certain tuning behaviors.

Overall sound quality is good for the money and enjoyable for workouts and casual listening, but it does not deliver premium detail, depth, or polish.

Overall sound is widely praised as rich, engaging, and detailed, though it is not tuned for strict neutrality; a few reviewers find the stock profile too boosted at the extremes and harder to correct due to limited EQ.

Soundstage is commonly described as roomy and spacious for earbuds, with immersive modes able to expand the sense of space further (sometimes with tonal side effects).

Spatial/immersive audio features are robust and can sound more natural than many implementations, but not everyone prefers the processing, and it typically reduces battery life.

Stability is one of the product's best traits, with the twist-lock wing design keeping the buds secure through running, gym work, and sweaty sessions.

Fit security is a major strength thanks to stability bands/wings, with several reviews calling them suitable for workouts and even running, though some users mention footstep thud in ANC mode.

Touch controls are usable but not ideal for exercise, with some lag and reduced reliability versus physical buttons, especially with sweat or gloves.

Touch responsiveness is generally strong and often praised for quick gesture recognition, but sensitivity can lead to accidental triggers during fit adjustments or certain activities.

Transparency mode is the most divisive feature: one reviewer found it fairly natural, but the more detailed running-focused reviews said traffic awareness was still lacking.

Transparency/Aware mode is generally clear and natural, with useful loud-spike handling in some implementations, but several reviewers still place it behind the very best competitors and note occasional hiss or wind sensitivity.

Treble and upper-range clarity are only middling, with repeated comments about limited sparkle, detail, and openness up top.

Treble is often described as crisp and detailed without obvious harshness for many, though some reviews report boosted regions that can fatigue sensitive listeners and note limited EQ control to tame it.

USB-C charging is included and treated as an expected but welcome convenience for everyday use.

USB-C charging is standard and widely appreciated, with fast-charge behavior commonly referenced for quick listening time boosts.

Value is a major selling point, with every review framing the Endurance Race 2 as a feature-rich, sports-focused bargain that undercuts pricier rivals.

Voice assistant support is absent according to one review, which is a notable feature gap even at a budget price.

Voice assistant support is present via shortcut customization, with practical use reported (including Google Assistant), though it is not typically positioned as a headline differentiator.

Maximum loudness is below average for the category, and multiple reviewers had to raise volume more than expected during outdoor runs.

Volume output is frequently described as loud and satisfying, with enough headroom for travel and commuting environments.

The IP68 buds are extremely well-suited to sweaty training and rainy runs, making durability against dust and water one of the clearest strengths.

An IPX4 rating is repeatedly cited as sufficient for sweat and light rain, appropriate for workouts but not for full submersion scenarios.

Even though the shells are fairly large, reviewers still described them as light enough to stay comfortable during movement and longer sessions.
