Compare Poly Voyager Free 20 Earbuds vs Soundcore by Anker Space A40 Earbuds

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

Reviewers repeatedly found ANC strong for the price, especially against steady low-frequency noise, though a few noted weaker high-frequency cancellation and one called it subpar.

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

Android support is strong through LDAC availability and the Android Soundcore app, though LDAC-specific benefits are repeatedly limited to compatible Android devices.

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

The Soundcore app is a major strength, with reviewers praising customization, easy setup, EQ, ambient controls, and firmware/settings access.

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

aptX support is absent; PCMag directly notes the codec set excludes AptX.

Video sync and latency are generally good, with reviewers reporting minimal or no noticeable lag, though gaming mode improvements were sometimes described as small.

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

Bass is generally punchy and enjoyable, but opinions vary from light on sub-bass to somewhat emphasized or bass-heavy depending on EQ and reviewer preference.

Battery life was broadly praised, commonly around 8 hours with ANC and longer with ANC off or the case.

Battery life is a consistent strength, with long earbud runtime and large case reserves, though LDAC and ANC reduce the headline numbers.

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

Bluetooth support is broadly solid with Bluetooth 5.2, quick pairing, range praise, and mostly stable wireless performance, despite one review citing re-pairing issues.

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

Build quality is mostly considered solid or premium for the price, but case security, scratches, and lid fit drew isolated criticism.

Hi-res playback support is mostly evidenced through LDAC and Hi-Res audio certification rather than any separate built-in DAC discussion.

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 case is compact and often praised for design, wireless charging, and magnets, but reviewers also flagged weak lid closure, insecure hinges, or scratch-prone plastic.

Charging was strong, with repeated fast-charge mentions plus USB-C and wireless charging positives.

Charging is a strong feature because reviewers mention USB-C, wireless charging, and fast-charge claims around four hours from a short charge.

Codec support was a weak point because HP did not specify supported codecs in one review.

Codec support is broad for the class with SBC, AAC, and LDAC, but it lacks aptX.

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

Comfort is one of the strongest consensus areas, with many reviewers wearing the earbuds for hours or describing them as lightweight and easy to forget.

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

Design impressions are positive overall: reviewers call the buds small, sleek, stylish, luxe, compact, and pocketable.

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.

Fit is usually secure and well-sealed, though one reviewer found the largest included tips too small and another said getting the right fit took practice.

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

Ear tip coverage is strong, with most reviews highlighting five or six included sizes, although one reviewer with larger canals needed third-party XL tips.

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

Equalizer customization is a standout, with repeated praise for custom EQ, HearID, eight-band controls, and customizable preset options.

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

Find-device support appears in the app, but reviewers describe it as beep-based rather than true GPS-style tracking.

Frequency response is considered balanced or close to preferred targets by some reviewers, while others say it is fun rather than truly accurate for critical listening.

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

Case hinge/security feedback is negative where discussed, with SoundGuys specifically criticizing loose case hinges.

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

Included accessories are solid, especially the multiple ear tips and USB-C cable that several reviewers mention.

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

Instrument separation is generally good for the price, with several reviewers praising stereo placement, separation, or clean presentation.

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

The integrated microphones are present and functional, with six-mic arrays or onboard mics mentioned across reviews.

Single-bud and seamless left/right use are supported in the review evidence and described as working smoothly.

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

LDAC is a repeated strength and is often framed as a high-res or Android-friendly feature at this price.

Lossless-related support is limited and mainly appears through app sound-quality prioritization rather than broad lossless codec support.

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

Maximum-volume clarity is good where tested, with PCMag reporting no bass distortion at top volume.

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

Microphone noise reduction is mixed: some reviewers praise voice isolation in noise, while others say ambient noise or wind still hurts call quality.

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

Call microphone quality is mixed, ranging from clear and reliable to average, tinny, muffled, or poor depending on environment.

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

Midrange clarity is mostly good but not unanimous; reviewers praise vocals in some tracks while others describe veiled vocals or a desire for more mids.

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

Multi-platform use is helped by iOS/Android app access and reviewers using the buds across phones, tablets, laptops, and computers.

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

Multipoint is a major feature and usually reliable, though at least one review had connection switching/re-pairing complaints.

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

Passive isolation is consistently helped by the in-ear seal and is often described as good even before ANC is added.

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

Portability is strong because both the buds and charging case are repeatedly described as compact, pocketable, and easy to carry.

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

Preset EQ quality is strong, with reviewers repeatedly noting many presets that can improve or tailor playback.

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

Sensors are a weakness because multiple reviewers explicitly note no wear detection or auto-pause sensors.

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.

Smudge resistance is supported by the matte case finish, with one review saying it should not show fingerprints or scratches easily.

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

Setup and software usability are generally easy, with several reviewers calling the app simple or the setup straightforward.

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

Sound leakage appears favorable where discussed, with reviewers saying the buds kept sound private or avoided noise leakage.

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 broadly praised as clear, detailed, balanced, or excellent for the price, with only audiophile and tuning caveats.

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

Soundstage depth is positively mentioned in one review through depth and clarity, but it is less widely discussed than separation or width.

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

Soundstage width is mixed but generally decent, with praise for wide or spacious soundstage offset by one reviewer saying it is not wide.

Spatial audio scored low because one review explicitly said it is lacking.

Spatial audio is a missing premium feature according to WIRED, which explicitly lists lack of 3D spatial audio among the omissions.

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

Stability is strong for everyday use, with reviewers reporting snug fit, no falling out, and stable fit during activity.

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

Touch controls are customizable and often responsive, but several reviewers mention patience, missed taps, or finicky behavior.

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

Transparency mode is mostly useful and often praised, though some reviewers call it bright, hissy, tinny, or less natural than premium rivals.

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

Treble clarity is mixed: some hear crisp and clear highs, while others report spikes, thin cymbals, or less sparkle.

USB-C is well supported for the case and charging cable.

USB-C is well supported, with reviewers repeatedly mentioning USB-C charging or included USB-C cables.

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

Value is a strong consensus strength because reviewers repeatedly call the earbuds a bargain, great buy, or strong package for the price.

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

Voice assistant integration is available, but performance is mixed: some reviewers say pickup is good while Tom’s Guide found Siri and Google Assistant unreliable.

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

Volume output is strong enough for most listeners, with reviewers reporting loud output or a measured 113.6 dB peak.

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

Water and sweat resistance are adequate for workouts and light rain at IPX4, but reviewers caution it is not dunkable or waterproof.

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

Weight comfort is a major strength, with the light buds repeatedly described as low-fatigue or nearly disappearing in the ear.
