Compare Edifier NeoBuds Planar Earbuds vs Sennheiser CX 80U Wired Earbuds

ANC is widely described as effective or better than expected, though most reviewers stop short of calling it class-leading.

Android setup is straightforward, with Android recognition and Fast Pair both mentioned.

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

The ConneX app is widely described as useful and feature-rich, even if not every reviewer liked its look or behavior.

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

aptX family support is explicitly confirmed, including aptX Adaptive.

Where tested, video and gaming latency are described positively, with low-latency use called fine or strong.

Bass is the main dividing line: several reviews hear limited punch or body, while others report strong or satisfying bass once fit or tuning is dialed in.

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 usually judged average or mediocre for the price, though some reviews report acceptable day-to-day runtime.

Reviews note Bluetooth 5.4 support and solid wireless basics.

Build quality gets mixed-to-positive feedback, with some reviews calling the buds well-made and others criticizing cheap-looking materials.

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

Reviews repeatedly confirm hi-res playback support, though they focus on playback capability rather than DAC specifics.

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

Squeeze, pinch, and pressure controls are often described as deliberate and more reliable than typical touch inputs.

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 impressions are mixed, ranging from ugly or cheap-looking to robust and well-made.

Charging is a clear strength thanks to wireless support and quick top-ups.

Codec support is a major strength, with repeated praise for the unusually broad hi-res codec list.

Comfort is consistently strong, with several reviewers saying they could wear the earbuds for hours or all day.

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

Design is divisive: some reviewers call the earbuds modern or futuristic, while others simply do not like the look.

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.

With the right tip size, reviewers report an excellent seal and secure fit.

Multiple reviews confirm a wide ear-tip selection, typically spanning extra small through extra large.

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

The EQ offers real customization, but several reviews say it is limited, technical, or less effective than expected.

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

One review confirms a find-my feature that makes the earbuds beep when misplaced.

One review says the tuning stays reasonably close to the Harman curve.

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

Reviews confirm a generous bundle that can include multiple ear tips, a charging cable, manuals, and a pouch or carrying case.

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

Instrument separation and layering are a standout, with reviewers repeatedly calling the presentation clean and highly detailed.

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.

Multiple reviews explicitly mention a six-mic or three-per-side microphone setup.

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

LDAC support is repeatedly confirmed across reviews.

Lossless support is explicitly cited through aptX Lossless and related hi-res codec support.

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 mixed: some reviewers hear background suppression struggle, while others say it helps keep calls usable outdoors.

Call quality ranges from decent to very good, with clear pickup in good conditions but not universal best-in-class performance.

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

Midrange performance is generally clear and natural, but one review says vocals can dip back in the mix on some material.

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

Reviews describe straightforward use across Apple devices and Android, suggesting broad everyday compatibility.

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

Multipoint support is present and often works well, though some reviews report occasional sluggish or manual switching.

One review says the earbuds provide decent passive isolation with a proper fit.

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

One review calls the case very pocketable and easy to carry.

Presets such as Dynamic or Electrostatic are often useful, with reviewers finding modes that better suit their tastes.

Several reviews note customizable case lighting with multiple color options.

Wear detection and other onboard sensors are present, but wear-detection behavior is not consistently praised.

One review says the matte case finish helps prevent fingerprints.

Setup and pairing are often easy, but one review notes awkward app behavior across devices.

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.

Reviews repeatedly praise the NeoBuds Planar for detailed, high-fidelity sound, though one review found the tuning inconsistent from track to track.

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.

One review explicitly says the presentation has width but lacks depth.

Multiple reviews describe an open, spacious presentation with a large soundstage.

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

One review explicitly notes that spatial audio is not included.

Fit security is generally good, including for workouts and movement.

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

Controls are generally usable, but responsiveness and refinement are not universally praised.

Transparency mode is usable and sometimes helpful, but most feedback stops short of calling it natural or fully open-sounding.

Treble clarity is a recurring strength, with reviewers highlighting clean, precise highs and strong upper-frequency detail.

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

USB-C charging is explicitly confirmed in multiple reviews.

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

Value is the main weakness, with frequent pushback on the $299 price even from reviewers who liked the sound.

One review says native voice assistant commands are acted on swiftly.

Volume output is usable but not exceptional, with some reviewers saying the buds are not especially loud.

Reviews cite IP54 or IP55 protection for sweat, dust, and light weather exposure.

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

One review notes the 5.6g weight keeps them from feeling heavy.

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