Compare JBL Endurance Race 2 Earbuds vs Sennheiser CX 80U Wired 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.

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

USB-C compatibility is a clear strength, with successful use on Android phones in both reviews and no reported compatibility issues.

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

There is no companion app, which is typical for wired earbuds but still limits customization and feature depth.

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 punchy, agile, and clean rather than bloated, but both reviews suggest the very lowest bass lacks some rumble and weight.

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

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

Build quality is viewed positively, with one review specifically calling it impressive for such an inexpensive wired model.

One review specifically highlights the integrated DAC and 24-bit/96kHz playback support as a real value-add for budget wired listening.

The in-line controls are easy to press and responsive, but overall functionality is basic and volume adjustment is a notable limitation.

The cable looks slim and tidy, but the non-flat design can bunch up and tangle in a pocket.

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.

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

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

Comfort is one of the strongest recurring themes, with both reviews describing long listening sessions as easy and irritation-free.

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

The CX 80U looks understated and practical overall, with one reviewer liking the classy silver accents while another found the design too plain to stand out.

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 eartip sizes help users dial in both comfort and seal, which directly supports the earbuds' fit and passive isolation.

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

There is effectively no EQ customization here, so users cannot tailor the sound profile beyond tip choice and source settings.

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

Reviewers consistently describe the tuning as balanced and accurate for the price, with natural vocals, convincing tonal balance, and good detail retrieval.

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

The accessory bundle is basic but useful, mainly centered on extra eartips rather than premium extras.

Layering and separation are generally good for a budget model, though one review noted that mids are not as distinctly separated as on pricier alternatives.

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

An in-line mic is included for calls and voice use, but it feels more functional than premium.

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

At higher listening levels, the earbuds stay controlled and avoid the harsh or tinny edge that often hurts cheap wired earbuds.

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

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

Mic performance is acceptable but not exceptional, with decent vocal clarity offset by noticeable static in one review.

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

Mids are clear and robust, especially for vocals and acoustic material, though they do not reach the finesse of more expensive earbuds.

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

Cross-device compatibility is excellent for a wired USB-C model, with smooth use reported on phones, tablets, and laptops.

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

Passive isolation is a standout strength, with the seal doing a surprisingly strong job of reducing office chatter and everyday outside noise.

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.

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

Setup is about as simple as it gets: plug in the USB-C connector and start listening with no app, pairing, or extra steps required.

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 reason to buy the CX 80U, with both reviews describing it as unusually refined, detailed, and balanced for the price. The wired USB-C path delivers clean, detailed playback and is a big part of why these earbuds outperform many cheap rivals.

The presentation has more openness and spatial breathing room than expected at this price, helping the earbuds sound immersive rather than cramped.

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.

With the right eartips, the earbuds stay in place well enough for desk use and walking.

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

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.

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

Treble is vivid and expressive without turning harsh, which helps preserve detail and a sense of space.

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

USB-C is a major advantage here, making the earbuds feel current and widely usable across modern devices.

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.

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

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

No water-resistance rating is highlighted, so these are a poor fit for buyers who need workout or rain-friendly earbuds.

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

The earbuds are very light, which contributes to their easy long-session comfort and unobtrusive feel.
