Compare Sony WF-C710N Earbuds vs Technics EAH-AZ100 Earbuds

ANC was the clearest consensus strength, repeatedly described as highly effective, above its price class, and unusually strong for budget earbuds.

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

Android compatibility was positive where tested, including Android pairing and no cross-platform issues.

The app was mostly praised for control and customization, but some reviewers wanted easier setup, more features, or fewer connection frustrations.

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

aptX support was criticized as absent, especially because some cheaper or similarly priced earbuds offer it.

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

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.

Bass was one of the most praised traits, usually described as powerful, punchy, deep, or dynamic, with a minority saying it can overpower the mix or sound too heavy out of the box.

Charging was mixed: quick charging earned praise, but the lack of wireless charging was a repeated limitation.

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

Codec support was a recurring weakness because reviewers repeatedly criticized the earbuds for offering only AAC/SBC and lacking higher-quality options.

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

Comfort was a major strength, with many reviewers saying the earbuds remain comfortable for hours or even all day.

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

Design opinions were mixed but leaned positive, especially for the transparent Glass Blue finish; some reviewers found it toy-like or only average.

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

Eartip fit was usually secure and comfortable when the right size was found, though smaller ears and seal sensitivity remained caveats.

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

Integrated microphones were generally adequate to good for calls, with stronger indoor performance and weaker results in noisier conditions.

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

LDAC support was repeatedly called out as missing, which reviewers saw as disappointing for Sony earbuds and a drawback for serious listeners.

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

Lossless audio support was weak because one reviewer explicitly noted the lack of aptX lossless and LDAC.

Maximum-volume clarity was mixed, with reviewers noting muddier mids at high volume and occasional treble distortion.

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

Microphone noise reduction was often praised for wind and background suppression, but a few reviewers said voice quality suffers or becomes hard to understand in noisy settings.

Multi-platform compatibility was positive in the one review that tested both iPhone and Android without issues.

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

Multipoint was valued when it worked, but one reviewer reported disruptive dual-device buzzing, making reliability context-dependent.

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

Passive isolation received strong marks where tested, with reviewers crediting the ear tips and secure seal for blocking outside noise before ANC.

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

Portability was mostly good because the case fits pockets, though several reviewers called it bulkier than rivals or less ideal for tight pockets.

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

Preset EQ profiles were viewed positively when reviewers found bass boost, Excited, or Bright profiles useful for shaping the sound.

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

Wear-detection sensors were praised as smooth, useful, and battery-saving.

Sidetone was weak in one review because the earbuds did not feed enough of the caller’s own voice back during calls.

Smudge resistance was mixed, with one reviewer finding the case not fingerprint-prone and another saying it attracts fingerprints and dust.

Software/setup simplicity was mixed, with one reviewer praising guided EQ setup and others reporting frustrating app signup or connection issues.

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

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

Soundstage depth received positive comments around three-dimensional space, soundstage, and bass/soundstage impact.

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

One lab-based review credited the earbuds with wide, clearly defined spatial presentation.

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

Spatial audio support was not a major draw, with reviewers noting limited service support or calling the feature unimpressive.

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

Stability was polarizing: some reviewers had no fallouts, while others found the earbuds slipped during running or were insecure for workouts.

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

Touch control responsiveness was generally good, but repeated taps and accidental triggers made the control experience uneven.
