Compare Sennheiser CX 80U Wired Earbuds vs JBL Vibe Beam 2

ANC is generally a strength for the price, with strong praise in several reviews, though one reviewer found it not great.

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

Android compatibility is directly supported through Android pairing and Google Assistant or Gemini activation.

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

The JBL Headphones app adds meaningful value through control changes, EQ, ambient settings, video mode, and other feature controls.

Video sync and latency are strong points, with video mode, fixed lip-sync, and zero-latency gaming impressions all noted.

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

Bass is usually described as a JBL-style strength, but one reviewer found it weak out of the box and another wanted more bass.

Battery life is one of the strongest areas, with all reviews pointing to 40 hours total or strong earbud runtime.

Bluetooth is consistently positive, with Bluetooth 5.3, Google Fast Pair, easy pairing, and multi-device support mentioned across reviews.

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

Build quality is good for the price, though one review says the earbuds are not premium.

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.

Case quality is mixed: reviewers noted minimal water resistance and one awkward removal design, but also solid holding of the earbuds.

Charging is mixed: fast charging is praised, but multiple reviews call out the lack of wireless charging.

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

Comfort is mostly positive thanks to light weight and extended-wear comfort, though one reviewer’s ear shape caused fit trouble.

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.

Design impressions are positive overall, with reviewers liking the stem design, clean look, and JBL styling.

Fit depends on the listener, with one reviewer getting a good default seal and another reporting ear-shape-related issues.

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

Ear tip options are a plus because reviewers mention included smaller, larger, and multiple-sized tips.

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

EQ customization is a clear strength because reviewers repeatedly mention presets and user-created EQ profiles.

Find My support is present through the app’s Find My Buds feature, which makes an earbud beep.

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

Frequency balance leans colored rather than neutral, with the main review calling out a bass-heavy sound signature.

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

Included accessories cover the essentials, including the case, earbuds, USB-C cable, ear tips, and manual.

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.

Instrument separation is not a standout because one review specifically says it lacks the nuanced separation of a high-end model.

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

Integrated microphones are a clear feature, with multiple reviews noting four mics or two built-in microphones per earbud.

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

Microphone noise reduction is a weakness in the main review because wind and background noise make the voice muddy and distant.

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

Call quality is mixed and context-dependent, with four mics helping clarity but background noise still causing muddy or distant voice pickup.

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

Midrange feedback ranges from decent to clear, though one review says the bass-heavy tuning can overpower the mids.

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

Multi-platform compatibility is positive, with reviewers pairing to a Garmin watch, PC, Fire tablet, iPod, and multiple devices.

Multipoint is supported and presented positively, with reviewers noting switching between multiple Bluetooth devices.

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

Portability is supported by the case sliding into a pocket well, although foldability is not relevant to this earbud design.

Preset EQ support is useful, with reviewers using or listing JBL presets such as bass, vocals, club, and other modes.

Sidetone or Voice Aware exists, but quality is mixed because one reviewer barely noticed it while another lists it as adjustable.

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.

Setup simplicity is strong in one review that paired the earbuds easily with several devices.

Sound leakage is a concern in one review, which reports a lot of leakage from the earbuds.

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.

Sound quality is the most split area: some reviewers called it clear or excellent for the price, while others found it tiny, bass-limited, or merely decent.

Soundstage depth is limited, with reviewers noting the sound is not especially immersive or high-end in presentation.

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

The sense of width is limited; reviewers noted a non-immersive presentation and a soundstage that is not especially detailed or balanced.

Spatial audio is not a strength because one review explicitly says the earbuds do not provide an immersive experience.

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

Stability is mostly strong, with several reviewers saying the earbuds stayed secure for workouts or running.

Touch controls are useful and easy to access from the stems, with one reviewer praising quick ANC control.

Transparency and ambient features are useful but not premium; reviewers alternately called them good, basic, and slightly electronic.

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

Treble is mixed: some reviewers heard crisp highs, while others described the highs as washed out or overpowered.

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

USB-C is clearly supported through the port and included charging cable, with several reviews mentioning USB-C or Type-C charging.

Value for money is strong across reviews, especially for the $40-$80 price range and the feature set offered.

Voice assistant integration is supported through press-and-hold controls on either earbud.

Volume output appears strong in the one direct volume test, where the reviewer described the earbuds as pretty loud.

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

Water and sweat resistance are a practical strength, with IP54 for the earbuds repeatedly tied to sweat, splashes, dust, and workouts.

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

Weight comfort is a clear advantage, with reviews highlighting the 50 gram total weight and a barely-there in-ear feel.
