Compare Poly Voyager Free 20 Earbuds vs Audio-Technica ATH-CKS50TW Earbuds

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

ANC is consistently present and useful, but reviewer opinion ranges from very effective to average or clearly behind stronger noise-canceling rivals.

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

Android support is backed by Google Fast Pair, Android/Google device pairing, and aptX-related benefits for compatible Android phones.

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

The Audio-Technica app is a major strength, repeatedly praised for controls, codec options, battery information, firmware support, EQ, and listening modes.

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

aptX support is repeatedly confirmed, including aptX Adaptive in several reviews and standard aptX on compatible devices.

Low-latency and video sync performance is consistently strong, with reviewers reporting no perceptible delay or only a tiny delay.

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

Bass is one of the most supported strengths, described as deep, warm, impactful, and well suited to bass-forward listening, though not every reviewer found it exceptional.

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

Battery life receives the strongest agreement, with nearly every review emphasizing unusually long playback and case endurance.

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

Bluetooth support is generally strong through Bluetooth 5.2 and stable connection reports, though one reviewer experienced occasional signal drops.

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

Build quality is mostly positive, with sturdy earbuds and cases noted, though at least one reviewer criticized overall build confidence.

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

Physical buttons divide reviewers: some prefer their tactility and reliability, while others find them fiddly, awkward, or disruptive to fit.

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 sturdy or sleek in some accounts but repeatedly criticized as large, bulky, or inconvenient for pockets.

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

Charging is helped by USB-C and quick-charge performance, but several reviews mark the lack of wireless charging as a drawback.

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

Codec support is broad for the category, with SBC, AAC, aptX, and aptX Adaptive mentioned across reviews.

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

Comfort is generally better than the size suggests, but bulk and unbalanced weight make long wear more context-dependent.

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

Design earns mixed marks because reviewers like some clean or sturdy elements but often call the buds and case large, plain, or bulky.

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 often secure and comfortable with the right tips, though some reviewers warn that larger ears or wind isolation issues can matter.

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

Ear tip size coverage is solid, with multiple sizes included to help users find a seal.

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

EQ customization is a clear strength, with reviewers highlighting five-band adjustment, custom presets, and meaningful tuning control.

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

Find My-style support is limited but present through the app’s ability to locate the earbuds.

Frequency balance is praised in the clearest review evidence, with the full range represented without obvious overstatement.

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 basic but useful, especially extra silicone ear tips and charging cable references.

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

Instrument separation and detail placement are mostly strong, though one reviewer expected more from the large housings.

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

The earbuds include built-in or dual microphones, supporting calls and app-enabled voice features.

Left/right flexibility is a notable strength, with independent single-bud use and TW2 magnetic snap-together behavior documented.

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

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

Maximum-volume clarity is mixed: one review notes slight compression at louder volumes, while another praises detailed treble at high volume.

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

Microphone noise handling is the weak side of call performance, working better in quiet settings than in wind, music, or busy streets.

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

Call quality is generally usable to good, with several positive comments, but some reviewers rate it merely adequate or average.

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

Midrange clarity is mixed because vocals and mids can be clean and natural but are sometimes recessed by the bass-forward tuning.

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

Multi-platform use is supported by evidence of quick switching and pairing across a phone and tablet.

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

Multipoint connectivity is repeatedly confirmed and generally described as useful for switching between computers, phones, tablets, or calls.

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

Passive isolation is strong when the seal works, aided by the earbud housing and silicone tips.

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

Portability is a recurring weakness because the case is often described as too large, bulky, or hard to pocket.

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

Preset EQ quality is supported by the Clear Vocal preset fixing a vocal detail issue in one review.

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

Sensors score poorly because multiple reviews mention missing wear detection or desired auto-pause behavior.

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

Sidetone is a useful call feature, helping wearers hear their own voice naturally during calls.

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 is generally simple through automatic power-on, fast pairing, Google Fast Pair, and quick reconnection.

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.

Overall sound quality is widely liked for warm, satisfying, bass-friendly performance, though a few reviewers stop short of flagship praise.

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

Soundstage depth is mostly respectable, but the image can feel close or less expansive than some reviewers hoped.

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

Soundstage width is often praised as wraparound, broad, or convincing, despite one reviewer wanting more width.

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

Spatial audio is split: some reviewers found 360 Reality Audio immersive, while one found the 3D effect disappointing and others note service limits.

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

Stability is generally good for workouts and head movement, though one TW2 review finds the bulky fit unsteady.

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

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

Hear-through mode is useful and often decent, but reviewer praise is less consistent than for battery or EQ.

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

Treble is usually clear and present, but some reviews find it subdued, less sharp, or deliberately softened.

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

USB-C charging is repeatedly documented and functions as the main wired charging method.

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

Value is mostly favorable because battery, features, and sound compete well around the price, though one reviewer strongly prefers a lower sale price.

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

Voice assistant support is basic and mixed, with device-assistant access noted but no built-in voice-assistant control.

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

Volume control is flexible through app step options and the earbuds can get loud.

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

Water and sweat resistance is consistently supported, with IPX4 for the original model and IP55 noted for the TW2.

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

Weight comfort is mixed because the buds are heavier or unbalanced for some but still wearable for others.
