Compare Poly Voyager Free 20 Earbuds vs Denon Perl Pro True Wireless Earbuds

ANC was one of the strongest consensus points, repeatedly described as effective against office, commute, fan, and low-frequency noise.

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 compatibility was supported by app availability and Android, Pixel, or Samsung testing.

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 Poly Lens app is important and feature-rich on mobile, but desktop functionality and firmware workflows drew criticism.

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 was not confirmed; the only evidence flags uncertainty around advanced codec support.

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 was divisive: some reviewers heard strong or punchy low end, while others found it timid or lacking energy.

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 was broadly praised, commonly around 8 hours with ANC and longer with ANC off or 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.

Bluetooth support was strong overall, with Bluetooth 5.4, stable pairing, and good range mentioned despite setup quirks.

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

Build quality was mixed: earbuds were described as solid or well built, while the case and hinges felt fragile.

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

Control usability was mixed: push buttons prevent accidental touches but often push the buds into the ear and require pressure.

The included cable drew criticism for being very short.

Case quality was split: reviewers liked magnets, size, and style, but several criticized plastic feel, loose hinges, and fingerprints.

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

Charging was strong, with repeated fast-charge mentions plus USB-C and wireless charging 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 was a weak point because HP did not specify supported codecs in one review.

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.

Comfort was mostly strong, with multiple reviewers reporting long wear or low fatigue, although one had soreness after a couple of hours.

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 was generally liked for its sleek, professional, black-and-gold or lightweight look.

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.

Dongle support is absent, and reviewers called out the missing USB dongle compared with more work-focused alternatives.

Fit was a recurring strength, aided by fit tests and tip choices, though fit still depended on ear size.

Ear tip options were strong because multiple reviews confirmed four sizes or multiple tips.

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 was a repeated weakness, with reviewers wanting more than limited presets or a custom curve.

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

Find My-style location support appears in Poly Lens, but evidence is limited to last-known or location features.

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.

Hinge durability was a concern because reviewers found loose hinges on the charging case.

Included accessories were solid, with ear tips, charging case, and USB-C cable included.

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

One review praised the earbuds for balancing different sounds, supporting strong instrument separation.

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

Integrated microphones are a core feature, with repeated references to three mics per bud or six noise-canceling microphones.

LDAC support was not confirmed; the only evidence flags uncertainty around advanced codec support.

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

Maximum-volume clarity was limited by peaking and high-frequency distortion in one review.

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

Noise reduction for calls was praised for reducing background noise and helping voices stay clear.

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

Call quality was consistently positive, with reviewers hearing clear, understandable voice pickup.

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 clarity was generally a strength, with repeated comments about clear vocals and mids suited to calls and podcasts.

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.

Multi-platform compatibility was strong across phones, laptops, Windows, iPhone, MacBook, Android, and general Bluetooth use.

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 major work-use strength across phone and laptop pairings, though one reviewer noted switching delays.

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

Passive isolation was decent to strong because the sealed tips fully plugged the ears before ANC was considered.

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 was helped by a slim case that fits in a pocket.

Preset EQ options were limited to Bass, Flat, and Bright and were often described as underwhelming or too similar.

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.

Sensors were useful for wear detection, call answering, and media pause/resume behavior.

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.

Sidetone adjustment scored poorly because one reviewer said the Free 20 lacked the ability.

Smudge resistance was poor, with multiple reviewers calling out fingerprints and scratches.

Setup and software simplicity were mixed: basic setup could be straightforward, but firmware and desktop support created friction.

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.

One review referenced a fit test for audio leakage, suggesting leakage control depends on getting a proper seal.

Most reviewers described sound as good to excellent, especially for calls, vocals, and everyday music, though one found music compressed and shallow.

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 depth was mixed, with one review finding it unexciting and another finding it immersive.

Soundstage impressions were mixed, ranging from solid but unexciting to spacious and immersive.

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 scored low because one review explicitly said it is lacking.

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 was good, with reviewers noting no slipping, secure fit, and fit-test support.

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 scored poorly because one review stated the earbuds have no touch controls.

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

Transparency mode was useful in some reviews but less consistent, with complaints about switching friction or weak amplification.

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 came through clearly in some reviews, but one reviewer heard high-frequency distortion at maximum volume.

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 is well supported for the case and charging cable.

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

Value was strongest when discounted or judged against sound and ANC performance, but one review felt $150 was pricey.

Voice assistant support is present through controls, though evidence focused on activation rather than deeper integration.

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

Volume output was treated as a strength in hands-on use, though evidence was limited.

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

Water and dust resistance was a positive feature across reviews, though one reviewer warned against running water.

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

The earbuds’ low weight was repeatedly tied to easy long-session comfort.

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