Compare Poly Voyager Free 20 Earbuds vs Technics EAH-AZ100 Earbuds

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

ANC is widely rated top-tier for everyday noise and transit rumble, but several reviews stop short of calling it the absolute best in the category. Noise control is highly adjustable, with adaptive ANC plus granular sliders that let you tune intensity and reduce pressure effects.

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

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

The Technics Audio Connect app is feature-rich (ANC, EQ, multipoint, spatial settings), but some reviews call the interface clunky or menu-heavy.

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

Several reviews explicitly note aptX codecs are not supported.

Where tested, audio-video sync is reported as excellent with minimal to no noticeable lag.

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

Bass is repeatedly called deep and unusually controlled for true wireless, though one review found it can feel heavy or change with ANC settings.

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

Battery life is commonly reported around 10 hours with ANC on (AAC) plus substantial case recharges, with lower figures when using high-res modes.

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

Bluetooth stability is generally reported as reliable with few dropouts across devices and environments.

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

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 generally pocketable and premium-feeling, but some reviews mention weak magnets, slight rattle, or scratch/scuff issues.

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

Charging is praised for USB-C plus Qi wireless and quick-charge support; full recharge times are typically a few hours.

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

Codec support is strong (SBC/AAC plus LDAC and LC3/LE Audio features noted), appealing to both iOS users and Android audiophiles.

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

Comfort is widely rated high thanks to a smaller/lighter fit, though some users may still experience fatigue or fit variability over long sessions.

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

Design is viewed as premium and more compact than the prior model, though not everyone finds it the sleekest-looking option.

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.

Multiple ear tip sizes are commonly included, helping most users achieve a seal, though tip choice remains key to fit.

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

EQ customization is a strength, often cited as an 8-band EQ plus presets that can significantly change the sound.

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

Find My/location features are present, but feedback varies; some appreciate the feature, while others complain the locating beep or accuracy is limited.

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.

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

Instrument separation is frequently praised on busy tracks, helping the AZ100 stay clean and layered.

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 support is frequently highlighted for higher-quality Android streaming, with the usual battery-life tradeoff.

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

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

Voice noise reduction is often effective at cutting wind and background noise, though aggressive processing can create artifacts.

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

Call quality is mixed: many find it usable or improved, while others report robotic processing or, in one case, serious call glitches.

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

Midrange is generally clear and natural for vocals, with occasional notes that bass-heavy mixes can push voices slightly back.

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

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

Three-device multipoint is a major differentiator and is often described as seamless; occasional switching lag is mentioned but not common.

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

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.

Preset EQ options are generally useful, though some (like extra-bassy modes) may be too much for neutral listeners.

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

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.

Case finish durability is mixed, with some noting scratches/scuffs and others calling it relatively scratch-resistant.

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

Setup is mostly straightforward, but the lack of a case pairing button and some app UX quirks can add friction.

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.

Reviews consistently praise the AZ100 for highly detailed, spacious sound with strong dynamics; a few note the default tuning can be bass-forward or benefit from EQ.

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 a standout: multiple outlets describe an immersive, wide presentation that feels larger than typical earbuds.

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

Dolby spatial audio/head tracking is supported and can add immersion, but some reviewers find it subtle or prefer it off for music.

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

Fit stability varies: many report a secure hold, while some reviewers experienced looseness or buds falling out during vigorous movement.

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

Touch controls are responsive and highly configurable, with the main complaint being occasional over-sensitivity.

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

Transparency/ambient mode is strong and adjustable, but some reviewers note hiss at higher levels, an unnatural voice-focused mode, or not enough outside sound for awareness.

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

Treble is described as airy and detailed without harshness, but a few critics wanted more sparkle or presence.

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

USB-C charging is consistently supported and frequently mentioned as a modern convenience.

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.

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

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

The earbuds are commonly cited as IPX4-rated for sweat and light rain, but not for heavy water exposure.

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