LDAC codec support pushes Bluetooth bitrates to 990kbps, revealing nuances in high-res tracks. DSEE HX Extreme cleverly upscales compressed MP3s, restoring lost harmonics. While not perfect, it makes streaming services like Spotify sound fuller.

Compared to AirPods Pro, these earbuds offer wider soundstage depth. Instruments occupy distinct spaces rather than blending together. For critical listening, this technical prowess justifies choosing older hardware over newer rivals.

Battery Life and Charging Efficiency

What separates good tech from great? Endurance that outlasts your day. With up to 12 hours of playtime per charge (ANC off), these buds demolish the 5-hour average of competitors. Even with noise cancellation active, you’ll squeeze 8 hours—enough for cross-country flights or back-to-back meetings.

The compact case packs serious reserves. It adds 24 hours with ANC or 36 without—triple the capacity of many 2025 models. Forget nightly charging; a weekly top-up suffices for most users. Real-world testing shows 7h25m ANC runtime, matching Sony’s claims.

Need power fast? Five minutes in the case delivers an hour of music. The dual USB-C/Qi charging options cater to desk workers (wireless pad) and travelers (cable). Full case recharge takes 90 minutes—on par with premium rivals.

Using LDAC for high-res audio? Expect 20% shorter battery life. It’s a fair trade: enjoy lossless tracks during workouts, then switch to AAC for marathon sessions. This flexibility keeps the XM4 relevant against newer buds prioritizing either quality or longevity—rarely both.

Connectivity and Bluetooth 5.2 Experience

Seamless connections define modern tech experiences. The latest Bluetooth 5.2 standard delivers faster pairing and lower latency than older versions. While not cutting-edge in 2025, it maintains reliable performance for most users.

Pairing Process and Device Compatibility

Android users enjoy one-tap setup via Google Fast Pair—just open the case near your phone. iOS requires manual pairing but maintains stable connections afterward. Both platforms benefit from:

• LDAC codec support for high-resolution streaming on compatible devices
• AAC optimization for Apple products
• SBC baseline compatibility for older gadgets

Connection range covers typical home layouts but struggles through thick concrete walls. Testing shows stable audio up to 30 feet in open spaces. However, signal drops occur after passing two interior walls.

The lack of multipoint pairing forces manual switching between phones and laptops. Fitness enthusiasts might find this inconvenient mid-workout. Single-bud use works only with the right earbud—a limitation for left-ear preferrers.

Despite these quirks, the Sony WF-1000XM4 handles daily wireless needs effectively. The companion app simplifies codec selection and firmware updates. Audiophiles will appreciate lag-free video sync across streaming platforms.
