Sony WF-1000XM4 Wireless Earbuds Review – Silky Sound, Smart ANC and Premium Features

Designing a successor to a category-defining bestseller is never an easy task. With the Sony WF-1000XM4 wireless earbuds, Sony refines an already iconic formula by focusing on sound quality, active noise cancellation, and intelligent features that genuinely enhance everyday listening. Even in this renewed (refurbished) version, the WF-1000XM4 remains one of the most compelling true wireless earbuds on the market.

Design & Comfort

The Sony WF-1000XM4 feature a compact, ergonomic design that fits securely in the ear without creating pressure. Sony’s extensive experience with in-ear headphones is evident here: the rounded housing and lightweight construction make these earbuds comfortable for long listening sessions.

Unlike many competitors, Sony includes foam ear tips instead of standard silicone. These tips expand gently in the ear canal, improving passive noise isolation and comfort while reducing fatigue. The earbuds are also IPX4 water resistant, making them suitable for workouts, commuting, and everyday use.

Sound Quality & Audio Performance

Sound quality is where the Sony WF-1000XM4 wireless earbuds truly excel. The tuning is balanced and refined, delivering a natural and immersive listening experience across all genres.

• Bass is deep, tight, and controlled, offering impact without overpowering the mids.

• Midrange is clear and detailed, allowing vocals and instruments to sound natural and engaging.

• Treble is smooth, silky, and never harsh, even at higher volumes.

Thanks to Sony’s high-efficiency dynamic drivers and lightweight diaphragms, these earbuds provide excellent transparency and resolution. Whether you listen to electronic music, jazz, classical, or podcasts, the WF-1000XM4 maintain clarity and coherence.

Active Noise Cancellation (ANC)

Sony’s active noise cancelling is among the best in the true wireless category. Each earbud uses multiple microphones combined with Sony’s V1 processor to analyze and suppress ambient noise in real time.

Low-frequency sounds such as traffic, engines, or airplane noise are effectively reduced, while wind noise suppression improves outdoor usability. The ANC adapts automatically based on your environment, eliminating the need for constant manual adjustments.

Battery Life & Charging Case

Battery life is another strong point:

• Up to 8 hours of playback with ANC enabled

• Up to 12 hours without ANC

• An additional 16 hours via the charging case

The charging case supports USB-C fast charging, providing hours of playback from just a short charging session. For true wireless earbuds with powerful ANC, this level of battery life is excellent.

App Features & Smart Functions

The Sony Headphones Connect app unlocks the full potential of the WF-1000XM4. Through the app, users can:

• Customize EQ settings

• Enable adaptive sound control

• Activate 360 Reality Audio

• Optimize sound based on ear shape (via photo-based analysis)

Smart features such as Speak-to-Chat automatically pause music when you start talking, while ambient sound modes let external noise in when needed.

Connectivity & Call Quality

Bluetooth 5.2 ensures a stable and reliable connection. The WF-1000XM4 support SBC, AAC, and Sony’s LDAC codec, allowing high-resolution audio on compatible devices.

Call quality is excellent thanks to beamforming microphones and bone-conduction sensors that isolate your voice from background noise. Phone calls remain clear even in noisy environments like streets or public transport.

Real-World Use

The Sony WF-1000XM4 wireless earbuds perform exceptionally well in real-life scenarios:

• Daily commuting and travel

• Long flights and trains

• Work-from-home calls

• Gym sessions and light workouts

• Relaxed music listening at home

Their combination of comfort, ANC, and sound quality makes them extremely versatile.

• Bose QuietComfort Earbuds – excellent ANC, warmer sound

• Bowers & Wilkins PI7 – more audiophile-focused tuning

• Sennheiser Momentum True Wireless – detailed, analytical sound
