Compare Denon Perl Pro True Wireless Earbuds vs Nothing Ear (a) Earbuds

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.

ANC is consistently rated as very good for $99: strong enough for commuting, offices, and travel, but still a step below the very best premium earbuds. The ANC controls are a plus, with multiple levels and adaptive behavior giving users more flexibility than many earbuds at this price.

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.

Android users get extra upside from features like Fast Pair and LDAC, making the Ear (a) a particularly good value outside closed ecosystems.

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.

Nothing X is widely praised for being clean, stable, and genuinely useful rather than filler software, adding meaningful value to the overall package.

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 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.

Bass is energetic and satisfying, with enough weight for pop and hip-hop, but the default tuning can lean bass-heavy until you dial it back in the app.

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.

Battery life is a clear plus overall, especially with ANC off, and most reviewers found the case and quick top-ups easy to live with day to day.

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

Bluetooth stability is mostly solid, but there are scattered reports of stutters in interference-heavy areas, so reliability is good rather than flawless.

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

General build quality is good enough for the price, but the clear plastics and case finish draw some concern about scratches, creaks, and long-term wear.

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

The case is generally liked for its smaller footprint and pocketability, though some reviewers found it fiddly to open, awkward to load, or prone to cosmetic wear.

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.

Charging is convenient thanks to fast USB-C top-ups, but the missing wireless charging is one of the most repeated compromises in the reviews.

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.

Codec support is strong for the price, covering AAC and SBC broadly while also adding LDAC for higher-quality Android listening.

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.

Long-session comfort is one of the most consistently praised traits, with reviewers repeatedly calling the earbuds easy to wear for hours without fatigue.

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.

Design is a major selling point: the transparent Nothing look feels distinctive, stylish, and far less generic than most earbuds in this price band.

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

The included tip selection works for most listeners, but the fit options are not especially expansive, so very small ears may need more trial and error.

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

EQ options are helpful and easy to use, but customization depth is limited versus pricier models because the Ear (a) relies on a simpler 3-band approach.

Find My is a small but appreciated bonus that makes the feature set feel unusually complete for budget earbuds.

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.

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.

Where instrument separation was discussed, the Ear (a) performed well, making layered parts and small details easier to pick out than expected for budget buds.

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

LDAC support is a real differentiator in this segment and repeatedly mentioned as one reason the Ear (a) feels more premium than its price suggests.

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

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

Voice isolation can be impressively effective in some tests, yet reviewer consensus is more mixed once wind and heavier background noise enter the picture.

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.

Call quality is usually clear enough for everyday use, but it is not universally excellent, with some reviews reporting compressed or only average-sounding calls outdoors.

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.

When reviewers called out the mids, they usually praised clear vocals and an open midrange, though the tuning is still more fun than strictly neutral.

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.

Cross-platform behavior is a quiet strength, with reviewers liking that the core experience works well across Android, iPhone, and PC instead of favoring one ecosystem too heavily.

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

Multipoint is a standout convenience feature here, with most reviews praising smooth two-device switching, though a few noticed occasional prioritization hiccups.

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.

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.

In-ear detection and related sensor-based conveniences add polish, though fit sensitivity can occasionally trigger false pauses until the tips are dialed in.

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.

Setup and day-to-day software use are repeatedly described as fast, intuitive, and frustration-free, which helps the earbuds feel polished beyond their price.

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.

Across the reviews, sound quality is the Ear (a)'s biggest strength: lively, clear, and more refined than most sub-$100 rivals, even if it stops short of true flagship polish.

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.

Several reviews describe the presentation as wider and more spacious than expected at this price, helping music and movies feel less boxed in.

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

Fit security is usually strong enough for commuting and light workouts, though a few reviewers still had occasional loosening depending on ear shape and activity.

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

The pinch-based controls are usually described as responsive and more reliable than typical tap controls, although some advanced gestures take practice.

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.

Transparency mode is usable and sometimes above average for the class, but it is also one of the most common weak spots, especially versus flagship rivals.

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.

Treble detail is generally strong for the class, but some listeners noted the top end is not as airy or extended as pricier earbuds.

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

Voice assistant integration is supported through touch controls, with reports of common assistants working reliably when mapped.

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

Volume output is strong, with enough headroom for outdoor use, though not every reviewer found it exceptionally loud versus the broader market.

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

The buds are seen as gym- and commute-friendly thanks to their splash resistance, but the lower-rated case means the protection is not equally robust everywhere.

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