Compare JBL Endurance Race 2 Earbuds vs Denon Perl Pro True Wireless 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.

ANC effectiveness is usually rated good but not class-leading; it can handle commute rumble well, yet several reviewers say Sony/Bose options suppress more, especially in the upper ranges. Noise cancelling and awareness modes are often limited in fine control, with some reviews noting on/off style behavior and few intensity tweaks compared with competitors.

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

Android compatibility is good overall, and Android users with aptX-capable Snapdragon devices can get the most from Lossless/Adaptive modes; on other phones it still works well but with fewer codec benefits.

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 companion app is feature-rich for personalization, EQ, control mapping, and updates, but some sources mention slow loading or occasional instability, and several note it is effectively required to get full value.

aptX support is a highlight, with repeated mentions of aptX Adaptive/Lossless (and sometimes aptX Voice) as a key advantage for compatible Android devices.

Video latency is generally reported as well controlled, with reviewers noting little to no audio-video sync issues during typical streaming and YouTube viewing.

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 frequently praised as impactful and well controlled, with Immersion mode letting you add heft without obvious bleed; a few listeners still find the default or certain profiles bass-light or overly sculpted.

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 marketed as long, but real-world reports vary, with at least one standardized test landing closer to about six hours; most still consider it adequate for daily use.

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

Bluetooth stability is mostly strong with quick reconnects, though at least one review reports occasional stuttering in specific conditions.

Build quality is generally viewed as solid and premium-feeling, with durable housings and a well-made overall package.

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 charging case is often described as somewhat bulky but generally sturdy with strong magnets; a few comments mention hinge/handling quirks.

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

Charging is a strong point with fast-charge support and both wired and wireless options, though a small number of users report the case can get warm on a wireless pad.

Codec support is broad, including aptX Adaptive and aptX Lossless alongside AAC/SBC; the main caveat is that benefits depend on having a compatible source and LDAC is missing.

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

Long-wear comfort is highly personal: some find the fit secure and comfortable, especially with wings, while others report pressure, heat, or discomfort due to the large shells.

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 distinctive and polarizing: the large circular faceplate stands out, but many note the buds are physically big and may look or feel awkward in 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.

Ear tip options are generous, typically including several silicone sizes plus at least one foam set, which helps comfort and isolation when matched correctly.

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

EQ options are strong for the category, typically including a 5-band ProEQ plus an Immersion bass slider to fine-tune tonality after personalization.

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

Frequency response accuracy is divisive: some praise a balanced, natural tuning once updated, while others cite measured or perceived tonal issues out of the box that may require firmware and EQ.

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

Included accessories are a highlight, with multiple tip sizes, foam options, and stabilizing wings helping users dial in fit and seal.

Instrument separation and imaging are commonly highlighted as a standout, with precise placement and clean layering across busy mixes.

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

LDAC is repeatedly called out as not supported, so Android users who rely on LDAC for high-bitrate Bluetooth may prefer alternatives.

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

Clarity at higher volumes is typically strong, with multiple sources noting low distortion and intelligible detail even when played loudly.

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

Noise and wind reduction on calls is frequently reported as effective, helping keep speech understandable in busy or windy environments.

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

Call quality is generally above average, with voices described as clear and intelligible; a few reviewers still note slight processing or that top rivals edge it out.

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 and present, but can sound forward or radio-like depending on the AAT profile and firmware, so some users prefer minor EQ adjustments for balance.

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

Multi-platform use is supported across phones and computers, but fidelity and feature access can vary by platform, with iOS often limited to AAC and Android benefiting more from aptX.

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

Multipoint connectivity is a consistent win, with reviewers reporting reliable dual-device pairing and fast handoff between phone and computer/tablet.

Passive isolation depends heavily on getting a good seal; with the right tips, attenuation is described as decent, but it is not the main selling point versus active cancellation.

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.

Personalized AAT profiles can produce dramatic, often positive changes, but results vary by listener and tips; some profiles trade a sense of spaciousness for extra punch or focus.

In-ear sensors for auto play/pause are commonly mentioned and generally work as expected, with options to change or disable behavior in the app.

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

Setup and daily usability are good once configured, but some reviews describe the experience as less polished than rivals because controls and tuning can require initial tinkering.

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 the main strength: many reviews describe a clean, low-distortion, spacious and highly detailed presentation, especially after Masimo AAT personalization and/or EQ tweaks, though a minority found stock tuning or earlier firmware disappointing.

Soundstage is widely described as unusually wide and open for true wireless, with good spacing; a few reviews note it can feel a bit flatter in depth compared with the very best rivals.

Spatial audio gets mixed reactions: some find it immersive and bubble-like, while others call it subtle or underwhelming, and it is typically not head-tracked.

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.

Stability is usually good when the right tips and wings are used, though some users report slight movement during chewing or vigorous motion without added support.

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 commonly described as responsive and highly customizable, with reliable gesture detection and audible feedback.

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 or social mode is usable but mixed: some call it smooth and subtle, while others find it less natural, occluded, or slightly artificial versus AirPods-class passthrough.

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

Treble tends to be detailed and airy, but reports vary from smooth and controlled to tinny or over-sharpened on older firmware or specific personalized profiles.

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

USB-C charging is consistently supported and frequently mentioned as the standard wired option.

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 supported through touch controls, with reports of common assistants working reliably when mapped.

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

Volume output is often described as louder than average with plenty of headroom, useful for dynamic music and noisy 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.

IPX4 water and sweat resistance is consistently noted, making the earbuds suitable for light workouts and rain, though not for submersion.

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 a recurring tradeoff: the earbuds are heavier and more noticeable than many rivals, which can cause fatigue for smaller ears.
