Compare JBL Endurance Race 2 Earbuds vs Soundcore by Anker Space A40 Earbuds

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.

Across reviews, ANC is strong for the price, especially against steady low-frequency rumble (traffic, engines), but it is less consistent against voices and higher-frequency clatter; a few reviewers still call it merely adequate compared with premium flagships. ANC offers manual and adaptive modes plus strength presets, but several testers report little real-world difference between levels, and changing presets from the earbuds is limited; others find the adjustability useful enough to dial in.

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 strong, including access to LDAC and the full Soundcore app feature set on compatible devices.

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 Soundcore app is a major value add: it is usually described as straightforward, stable, and essential for unlocking features like EQ, control remapping, and firmware.

aptX support is explicitly absent in multiple reviews, so users prioritizing aptX should look elsewhere.

Latency and A/V sync are generally reported as good, especially for video; gaming modes exist, but several reviewers say improvements are subtle and best for casual mobile gaming.

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 tends to be punchy and fun, with some reviews noting a mid-bass lift; extension and sub-bass weight are more variable, and stock tuning can feel light down low for bassheads unless EQ is used.

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 a consistent highlight: real-world playback commonly lands around 6–8 hours with ANC and higher without it, with the case extending total time well beyond a full workweek for many.

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

Bluetooth stability is usually reliable with quick pairing and solid range, though at least one review reports intermittent re-pairing frustration that may require forgetting devices.

Overall build quality is solid for the price, though small durability concerns show up around case hinges and scratch-prone glossy interior surfaces.

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 compact and convenient with wireless charging, but some reviews flag lid/hinge security or imperfect closure that can risk accidental opening.

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

Charging features are premium for the price, typically including fast-charge boosts and wireless charging; real-world convenience is strong even if total runtime varies by codec and ANC.

Codec support is strong for the class (SBC/AAC with LDAC often available), but higher-quality modes can reduce battery life and may constrain other features like multipoint.

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

Comfort is a strong point thanks to the small shells and light weight; long sessions are generally easy, though a few users report minor pressure or discomfort after several hours.

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 frequently described as stylish and premium-looking for the price, with a compact, pocket-friendly aesthetic that does not scream budget.

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.

Multiple ear tip sizes are included (often five or six), improving fit odds; however, people with very large ear canals may still need third-party XL tips.

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 one of the standout features, with extensive presets plus custom multi-band control and HearID-style personalization that can noticeably refine mids/highs and bass balance.

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

Find My-style locating is present in some accounts, typically using audible beeps rather than true GPS tracking, and works as a practical backstop for misplaced buds.

Tuning is described as broadly balanced and inoffensive, with the ability to correct the signature via EQ; some note small tonal shifts when ANC is enabled.

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

Instrument separation and imaging are often highlighted as a strength, delivering good layering and placement for the money, though not at true flagship levels.

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

LDAC support is repeatedly called a key differentiator for Android users, enabling higher-bitrate streaming; expect higher power draw and the need to toggle settings in the app.

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

Maximum-volume clarity is mostly maintained, with limited distortion reported; tonal balance, rather than distortion, is the more common complaint at higher levels.

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

Mic noise reduction can be effective at separating voice from traffic or café noise, yet wind processing artifacts and aggressive suppression can reduce naturalness or intelligibility for some callers.

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

Call mic quality is mixed: indoor clarity is often fine, and some reviewers are impressed, but others report thin, muffled, or inconsistent voice pickup in louder or windy 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 is generally clear with decent vocal intelligibility, but a few reviewers note slightly veiled vocals or a cooler tuning that benefits from HearID/EQ tweaks.

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

Cross-platform support is good across iOS and Android, but the best codec features and some behaviors vary by platform (for example LDAC typically being Android-only).

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

Multipoint/dual-device connectivity is commonly praised as smooth and dependable, but at least one source claims it is missing and others note tradeoffs (like dropping to AAC/SBC when enabled).

Passive isolation is generally above average with a good seal, providing a solid baseline even before ANC; fit-dependent leakage is the main limiter if tips do not seal well.

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

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 plentiful and generally useful, giving workable options for music genres and spoken word; most reviewers still recommend light personalization for best results.

Wear sensors are a weak spot: multiple reviews call out the lack of auto-pause/in-ear detection, which reduces day-to-day convenience compared with some rivals.

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

Setup is generally easy with quick pairing, but the feature set can feel dense; most reviewers suggest using the app to configure controls, codecs, and listening modes early.

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.

Sound quality is widely praised for a sub-$100 set, with a clean, detailed presentation and lots of tuning flexibility; a recurring theme is that it is enjoyable rather than truly reference-grade for critical listening.

Soundstage is typically called wider than expected for compact buds, but still varies by listener and EQ, with some describing it as more in-head than expansive.

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 stability is generally good for daily use and light exercise, though the lack of stabilizing fins means heavy workouts and running can require occasional readjustment.

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

Touch controls are customizable and usually responsive, but several reviewers mention occasional missed taps, lag, or finicky behavior that takes practice.

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 mode is feature-rich (often with full and vocal-focused options) and can work well for quick conversations, but opinions diverge on naturalness: some hear hiss, brightness, or a narrow sound window.

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

Treble detail is good for the price, yet multiple reviewers mention either a treble spike/snappiness or a slight roll-off and reduced sparkle depending on tuning and ANC mode.

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

USB-C charging is standard and universally present, with quick top-ups frequently cited as genuinely useful.

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 integration is available but not always reliable, with reports of lag or misinterpreted commands on some platforms.

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

Peak volume is generally more than sufficient for most listeners, with at least one measured test placing it firmly in loud-enough territory without obvious strain.

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

The IPX4 rating is adequate for sweat and light rain but not for dunking or heavy water exposure; runners wanting more protection may prefer higher-rated alternatives.

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

Weight comfort is excellent, with the buds routinely described as lightweight and easy to forget once seated properly.
