Compare Technics EAH-AZ100 Earbuds vs LG xboom Buds by will.i.am

ANC is broadly strong and often near flagship level, though several reviewers say it still falls short of the very best Bose-style silence.

Noise cancellation is one of the clearest strengths, with reviewers praising how effectively it dulled or blocked low-frequency and everyday noise for the price.

Android compatibility is praised for LDAC, fast pairing, and strong ANC value with Android phones.

The app is mostly praised for useful controls, customization, stability, and EQ access, despite some complaints about layout.

The companion app is mostly praised for customization, fit testing, ANC controls, and clarity, though one short review criticized it.

aptX support is a weakness because one reviewer specifically wished Qualcomm aptX codecs were included.

aptX support is a weakness because TechRadar specifically called out the absence of aptX Adaptive as a limitation.

Video sync is mostly strong, with two reviewers reporting zero or no visible lag, while one notes a slight delay with some codecs.

Auracast support is a concern in one scored review because the reviewer criticizes its absence.

Auracast is repeatedly framed as a useful, uncommon, or unique feature that adds value if nearby broadcasts matter to the user.

Bass is widely praised for depth, control, punch, and low distortion, with only one review criticizing the default balance as too boomy.

Bass is a mixed strength: reviewers heard impact, depth, and fun energy, but several also connected the tuning to muddiness or reduced clarity.

Battery life is consistently a strength, with reviewers praising long ANC runtime and major improvement over the AZ80.

Battery life receives broad praise, with reviewers calling the figures strong, competitive, or impressive for the price.

Bluetooth reliability is consistently praised, with reviewers reporting stable connections and no meaningful dropouts.

Bluetooth setup is hurt by iOS pairing friction, with one reviewer criticizing the lack of automatic discoverability on iOS.

Build quality is praised as premium, tactile, mature, and a substantial step forward.

Hi-res playback is praised in the one scored review, where LDAC/FLAC listening brought more detail, solidity, and space.

Control remapping is praised as unusually flexible and useful across the app and earbuds.

Case quality is mixed: it is compact and pocketable, but multiple reviewers criticize weak magnets, rattle, scratches, or bland styling.

Carry case impressions are modest, with reviewers describing it as basic or cheap rather than premium.

Charging is viewed positively where evaluated, especially wireless charging and case convenience.

Charging is a positive in the available review evidence, especially because the buds topped back up quickly.

Codec support is praised for LDAC/LC3 breadth, but the absence of aptX is called a mild limitation.

Codec support is a drawback because reviewers criticized the lack of higher-resolution codec options.

Comfort trends positive thanks to smaller, lighter ergonomics, but fit fatigue and bulk remain concerns for some ears.

Comfort is sharply split: multiple reviewers found the rounded, bulky fit poor for long sessions, while others reported a comfortable fit.

Design and aesthetics are generally praised as premium, sleek, compact, or classy, though a few reviewers find the look plain.

Design and aesthetics are consistently weak, with reviewers calling the buds boring, bulky, not sleek, or visually uninteresting.

Eartip fit is generally good with the right size, but some reviewers report looseness, bulk, or falling out.

Eartip fit can be secure with a tight seal, but fit remains inconsistent because limited tip options and shape caused issues for some users.

Ear tip options are considered useful and generous, especially for finding the right fit across ear sizes.

Ear tip options are mixed: one reviewer achieved a snug fit, while another considered the number of options disappointingly modest.

EQ customization is a clear strength, with many reviewers praising the eight-band control and meaningful tuning options.

EQ customization is useful and can improve the sound, though reviewers agreed it does not fully erase the underlying tuning problems.

Find My support is useful for peace of mind, though one reviewer is disappointed by the location behavior.

Frequency response impressions are mixed: one review calls it strange, while others praise accuracy, balance, and low distortion.

Frequency balance needs adjustment, with TechRadar saying the buds require tuning for a more balanced sound.

Included accessories draw criticism where reviewed because foam tips are missing despite multiple silicone tip sizes.

Instrument separation is a standout strength, with reviewers hearing layers, voices, and complex arrangements as distinct and clearly placed.

Instrument separation is a limitation, with TechRadar noting that vocals, synths, and other elements were not layered enough.

The integrated microphone earns praise through whisper-style use, with one reviewer saying it could pick up every word.

Independent left/right earbud use is praised as convenient and useful when scored.

LDAC is received positively for higher-quality playback and better sound from compatible Android or hi-res sources.

LDAC support is absent, and reviewers treated that lack of higher-end codec support as a sonic limitation.

Maximum-volume clarity is praised for staying clean and distortion-free even at high levels.

Maximum-volume clarity is weak, with reviewers hearing distortion, fuzziness, or quality loss at high volumes.

Microphone noise reduction is polarized: several reviewers praise wind and background suppression, while one reports failed clarity and cutouts.

Microphone noise reduction is serviceable but imperfect, since higher-frequency background sounds could still get through.

Call quality is mixed, ranging from serviceable or excellent in some reviews to choppy, robotic, or poor in others.

Call microphone quality ranges from usable to excellent, with one reviewer reporting exceptionally clear call sound and others noting some tinniness.

Midrange and vocals are generally described as clear, detailed, warm, and more forward than the previous model.

Midrange clarity improves with tuning but can become muddy when bass dominates.

Multi-platform compatibility is praised because the app and customization work across iOS and Android.

Multi-platform compatibility is mixed: Google and Microsoft pairing was praised, while iOS pairing was criticized.

Multipoint is a major strength, with reviewers repeatedly praising reliable switching and three-device connectivity.

Multipoint is viewed as a useful perk, though the evidence is more about convenience than stress-tested reliability.

Passive isolation is viewed positively when the tips seal well, with reviewers noting isolation even before ANC is active.

Portability is strong because the case is repeatedly described as pocketable, small, and easy to carry.

Portability is strong because the case is compact and light enough to pocket easily.

Preset EQ quality is mostly positive, especially Direct, Dynamic, and Treble+ modes, though SuperBass+ is too heavy for one reviewer.

Preset EQ quality is uneven, with some presets improving individual tracks while treble-heavy tuning could sound harsh or tinny.

Setup and software simplicity are mostly positive, but the lack of a physical pairing button adds friction for one reviewer.

Software and setup are helped by the useful fit-test function and simple pairing experience on supported platforms.

Sound leakage is a weakness in the one scored review, which says loud music can be heard in a quiet room.

Sound leakage is a clear weakness in one review, especially above roughly 40% volume.

Reviewers overwhelmingly praise the AZ100's sound as clear, detailed, musical, and high-end, though one review found the stock tuning odd.

Sound quality is the most divisive area: some reviewers heard enjoyable or even stellar audio, while others found it muddy, unclear, or below rivals.

Soundstage depth is usually strong, with reviewers praising depth, immersion, and layering, though one long-term reviewer wanted more depth.

Soundstage depth is limited, with What Hi-Fi? describing the presentation as claustrophobic.

Soundstage width receives strong praise, with reviewers describing the presentation as spacious, broad, expansive, and room-like.

Soundstage width is limited, with reviewers wanting greater spaciousness and more expansive layering.

Spatial audio is mixed: reviewers appreciate Dolby/head-tracking support, but several find it merely decent, distracting, or less clear than stereo.

Spatial audio is a weakness because the product lacks the more immersive, three-dimensional focus found in pricier LG earbuds.

Stability is mixed: several reviewers found the fit secure, while others would not trust it for vigorous movement.

Stability is generally good thanks to hooks, seal, and secure fit, but it can fall apart when the eartips do not suit the wearer.

Touch controls are generally responsive and customizable, though sensitivity and personal preference create some mixed reactions.

Touch controls are mixed: they can be fast and responsive, but other reviewers reported accidental or phantom taps.

Transparency mode is mixed: some find it natural or useful, while others hear hiss, over-processing, or weaker situational awareness.

Transparency mode is praised as useful for letting outside sound through when needed.

Treble is usually considered clear, airy, detailed, and non-harsh, though one review says the default tuning lacks high-end content.

Treble clarity is inconsistent, sounding crisp in places but harsh or tinny without tuning.

Value is mixed-to-positive: reviewers like the premium feature set and sound, but several note the high price and strong competition.

Value for money is highly split: the buds bring ANC, battery, and features at a moderate price, but several reviewers preferred cheaper or clearer-sounding rivals.

Voice assistant integration is limited in coverage but works reliably where tested or described.

Volume output is praised as top-tier and very loud in the reviews that discuss it.

Volume output is a weakness because one reviewer found the buds quiet enough to push volume into leakage-prone levels.

Water and sweat resistance is adequate for workouts or rain, but one reviewer cautions against heavier rain exposure.

Water and sweat resistance is adequate for light rain and workouts, but review evidence does not frame it as a standout durability feature.

Weight comfort is praised because the earbuds feel better distributed, light, and easier to forget during use.
