Test Sony WF-1000XM6 (2026): ANC, LDAC and Real Battery Life

The WF-1000XM6 display 6.5 g per earbud, i.e. 0.6 g more than the XM5. The difference seems negligible on the scale, but it translates into a slightly increased shell volume, visible as protrusion beyond the auricle. On ears of standard morphology, this protrusion remains within acceptable limits. On smaller ears, the pressure of the housing against the antihelix is felt after 90 minutes of continuous wear.

The memory foam tips provided are the strong point of comfort. Their expansion capacity in the canal improves passive isolation (estimated attenuation of 22 dB in low frequency) and reduces pressure on the canal walls compared to classic silicone tips. Sony provides four sizes; we used size M throughout the test, with stable fit even during brisk walking.

The IPX4 certification covers water projections in all directions, not immersion. In practice, this means:

• Resistance to sweat during moderate sports sessions
• Use in light rain without risk
• Exclusion of rinsing under the tap or swimming

Stability in motion is correct, without ear hooks. We did not observe any dropouts during brisk walking sessions on the seafront in Vannes, including in sustained crosswinds.

The default signature of the WF-1000XM6 deviates from the Harman target curve in a characteristically Sony manner: pronounced sub-bass boost between 40 and 80 Hz (approximately +4 dB relative to the target), mids slightly recessed between 800 Hz and 2 kHz, and high-frequency presence correctly dosed to avoid excessive sibilance. This profile flatters genres with a strong rhythmic component (electronic, hip-hop, pop) but introduces a perceptible coloration on classical and acoustic jazz, where instrument bodies lack density.

The soundstage is wide for an in-ear model, with clear separation of planes on well-constructed stereo mixes. Scene depth remains limited, which is inherent to the in-ear format. Perceived distortion at high volume (85 dB SPL) remains low and only becomes audible on very short transients at full power.

The active noise reduction of the WF-1000XM6 relies on an adaptive algorithm that adjusts processing in real time according to the ambient sound profile. We conducted evaluations in three distinct contexts, with ambient level measurement using the reference sound level meter.

Rennes metro line B (rolling noise, 72-78 dB): attenuation is remarkable on low frequencies, with the rolling rumble disappearing almost entirely. The perceptible residue occurs on high transients (audio announcements, brake squeals) where ANC lets through approximately 8 to 12 dB more than on low frequencies.

Open-space (human voices, 58-64 dB): this is the most difficult ground for any ANC. The XM6 effectively attenuate the continuous background hubbub but let nearby and distinct voices filter through. Estimated attenuation on the 500 Hz to 2 kHz band is around 15 to 18 dB, which remains superior to the Bose QC Ultra Earbuds 2 on this register.

Long-haul flight (cabin noise, 82-87 dB): this is the environment where Sony ANC has historically excelled. The XM6 maintain this reputation with an estimated turbine airflow noise attenuation of 25 to 30 dB, making music listening comfortable at moderate volume (65 dB SPL).

The transparency mode of the WF-1000XM6 restores the environment with a slight coloration in the high frequencies, perceptible on short transient sounds such as horns or SNCF announcements. The own-voice resonance effect (perceived occlusion when speaking with the earbuds in place) is well controlled, less present than on the XM5.

The processing latency of transparency mode is estimated at 8-12 ms, which remains imperceptible in everyday conversation. In urban cycling, the reproduction of surrounding sounds is sufficiently natural to circulate safely, without the "saturated microphone" effect observed on certain competitors at 200 €.

The comparison with the AirPods Pro 3 remains unfavorable to the XM6 on this specific criterion. Apple maintains a perceptible lead on the naturalness of transparency mode, particularly on the reproduction of high-frequency transients (female voices, distant cymbals). The gap is not prohibitive for daily use, but it is measurable.

The WF-1000XM6 feature five microphones per earbud (three for voice capture, two for ANC feedback). During a call from a busy street measured at 74 dB, noise reduction on the transmit side handles the continuous traffic rumble effectively. The other party hears the voice with good intelligibility and without dominant ambient noise.

Two limitations identified during testing:

• Strong lateral wind (above 30 km/h) produces a residual low-frequency hiss audible to the other party, not filtered by processing
• High-pitched female voices nearby (conversation at 1 metre) partially leak through microphone reduction

In a quiet indoor setting, voice capture quality is clean, with slight dynamic compression that smooths volume variations. On Teams and FaceTime, perceived latency in video calls stays within normal limits (under 150 ms round-trip), with no noticeable lip-sync delay.

Sony announces 8 h with ANC on and 12 h with ANC off. The editorial team conducted measurements under controlled conditions: volume calibrated at 75 dB SPL, LDAC enabled, ANC in adaptive mode, ambient temperature 20°C.

Results measured by the Mute Zone team:

• ANC on, LDAC, 75 dB SPL: 7 h 55 min (slightly below Sony's claim, within the usual margin)
• ANC off, LDAC, 75 dB SPL: 11 h 42 min (below the announced 12 h, 18 min short)
• ANC on, AAC, 75 dB SPL: 8 h 31 min (36 min gain versus LDAC, consistent with codec power draw)

The charging case provides two additional full cycles with ANC on, for a total runtime of approximately 24 h. Wireless charging is absent on this model, a step back from expectations in the 300 € segment. Wired charging via USB-C from 0 to 100 % takes about 1 h 40 for the earbuds alone.

The Sony Headphones Connect app (Android and iOS) is stable in 2026, with synchronization times under 3 seconds. The interface has been redesigned: the most used settings (ANC level, EQ, wear detection) are accessible with two taps.

Features that genuinely change the experience:

• 5-band parametric EQ: allows correction of the default sub-bass boost to approach a neutral signature
• Speak-to-Chat: automatic pause on voice detection, improved responsiveness versus the XM5 (trigger in approximately 0.8 s)
• DSEE Extreme: upscaling of compressed files, noticeable effect on AAC 128 kbps, negligible on LDAC or FLAC files

Filler features or those with marginal use:

• 360 Reality Audio: requires a subscription and a compatible source, little content available in practice
• Adaptive Sound Control based on location: useful in theory, in practice profile transitions are sometimes delayed by 30 to 60 seconds

Multipoint works on two devices simultaneously. Automatic switching during an incoming call on the second device is operational but introduces a reconnection latency of 2 to 4 seconds, during which audio from the main source is cut.

The table illustrates a tight positioning among the three models at 300 €. The WF-1000XM6 lead on battery life and high-resolution codecs (LDAC, LC3), making them superior for the mobile audiophile on Android. The AirPods Pro 3 retain their edge on transparency and microphone quality, a decisive advantage for Apple users with frequent calls. The Bose QC Ultra Earbuds 2 stand out on voice attenuation in open-plan offices, a criterion often underestimated in generalist comparisons.

None of the three models dominates across all criteria. The choice depends on the priority usage profile, not on an overall hierarchy.

The WF-1000XM6 represent the best-argued choice for three specific profiles:

• The frequent traveler on Android: LDAC 990 kbps, effective ANC on a plane, battery life exceeding 7 h 30 with ANC on, case that doubles total battery life
• The mobile audiophile: configurable signature via EQ, LC3 support for compatible sources, low distortion at high volume
• The remote worker in an open-space office: reactive adaptive ANC, functional Speak-to-Chat, multipoint operational on two devices

Two profiles for which a 200 € alternative is sufficient:

• The exclusive Apple user: the AirPods Pro 3 offer better ecosystem integration, superior transparency and MagSafe charging at the same price
• The user focused on calls in open-space: the Bose QC Ultra Earbuds 2 attenuate human voices better on the 500-2000 Hz band, which is the number-one criterion in in-person meetings

The lack of wireless charging and the slightly higher weight than the XM5 are the two objective points of friction at 300 €. They do not call the positioning into question, but they must be factored into the purchase decision.
