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

Reviews consistently praise ANC for strong everyday isolation, especially against low-frequency noise, even if it is not described as class-leading versus premium rivals.

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.

One review says Google and Microsoft fast pairing makes setup with those devices simple, indicating solid Android-side compatibility.

App support is generally a strength thanks to EQ, ANC and control customization, but one short review says the app still feels lacking.

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

The only direct codec evidence is negative, with one review explicitly noting there is no aptX Adaptive 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 is repeatedly described as deep, impactful and weighty, though some reviews say the low end can dominate or muddy the presentation.

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 is a clear positive, with reviews repeatedly citing around 10 hours from the buds and roughly 30 hours total with 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.

One review explicitly confirms Bluetooth 5.4 with low-energy support.

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

Build impressions are mixed: one review says the buds themselves have decent build quality, while other design comments are less enthusiastic overall.

Case impressions are mixed-to-negative, with one review calling it basic and another saying it feels cheap.

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

Charging is described as quick, with one reviewer seeing the buds return to full after a short top-up.

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

Codec support is functional rather than premium, with SBC, AAC and LC3 confirmed but no evidence of higher-end wireless codecs.

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

Comfort is the biggest divisive point: several reviews call the buds bulky or tiring in-ear, while two shorter reviews describe them as comfortable.

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

Design is broadly seen as plain, bulky or utilitarian rather than stylish.

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

Fit can be snug and sealed with the right tips, though not every reviewer found the available options ideal.

The buds include multiple ear tip sizes, but reviewers still note that the selection is modest compared with some rivals.

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

EQ customization is a major strength, with multiple reviews highlighting custom tuning tools and flexible adjustment.

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

One review confirms a Find My feature that can play a sound to help locate the buds.

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

Tonal balance is inconsistent in the direct listening tests, with one review specifically calling the sound muddy.

Included extras are modest but useful, with extra ear tips and a removable hook specifically mentioned.

Instrument separation is a weak point, with one review explicitly saying these buds do not deliver phenomenal separation.

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

Integrated microphones are clearly present and feature-rich, with one review noting three mics per earbud.

LDAC support is directly criticized as missing.

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

Maximum-volume performance is a weakness, with one review saying clarity worsens at higher volumes.

Mic processing features are a strength, with reviews mentioning suppression of unwanted noise and dedicated wind-noise handling.

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

Call quality is generally good rather than class-leading, with reviews describing clear speech and one standout whisper-mode result, but also a little tinniness in one case.

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

Midrange clarity is mixed: some tuning improvements help, but muddiness remains a recurring complaint in other listening notes.

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

Cross-platform behavior is uneven, with iOS pairing friction specifically called out in one review.

One review highlights multipoint as a perk for maintaining connections with multiple devices.

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

Passive isolation benefits from a snug seal and secure in-ear fit when the right tips are used.

The small, lightweight case makes the buds easy to carry on the go.

Preset EQ modes are useful but inconsistent: they can improve some tracks, yet reviewers also describe the preset selection as limited.

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

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

Software and setup are not fully frictionless, with one review warning users to find the correct app.

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

Sound leakage is a clear weakness once volume rises past moderate listening levels.

Overall sound quality is highly mixed across the review set: some hear enjoyable, affordable tuning, while others call it a letdown that trails key rivals on clarity and refinement.

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.

Depth is limited, with one review specifically describing the presentation as claustrophobic.

Reviewers wanting a more open presentation are left unsatisfied, with one review explicitly calling for greater spaciousness.

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

One review says LG removed the focus on spatial, three-dimensional sound found in pricier alternatives.

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

Stability is generally good thanks to the hook and snug fit, although one review says that security is only moderate if the tips do not suit your ears.

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

Touch controls are polarizing: some reviewers found them fast and reliable, while others complained about phantom or accidental taps.

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

Transparency and ambient listening are described positively, with reviewers saying outside sound comes through naturally enough for awareness.

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 needs care: one review found crisp vocals on the right track, but others say the upper range can be overly forward or harsh.

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

USB-C charging is explicitly confirmed.

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

Value is mixed but not disastrous; several reviews see decent value or fair pricing, while others say stronger-sounding alternatives exist nearby.

Volume output is on the low side in one review, forcing louder listening and exposing leakage issues.

Water resistance is consistently listed as IPX4, making the buds suitable for splashes and light rain rather than tougher workout protection.

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