Sony WF1000XM4/B Noise-Cancelling Wireless Earbuds Black (Renewed)

The Sony WF-1000XM4 Noise-Cancelling True Wireless Earbuds represent Sony's flagship approach to portable audio, built around the custom Integrated Processor V1. This chip powers the industry-leading active noise cancellation while managing power efficiently enough to deliver up to 8 hours of battery life per charge. The newly designed 6mm driver unit produces clear highs, detailed mids, and rich bass, with enhanced noise cancelling performance even at low frequencies where many competitors struggle. Bluetooth 5.2 with LDAC codec support transmits approximately three times more data than conventional Bluetooth, letting compatible devices stream near-wired audio quality wirelessly.

Beyond sound quality, the WF-1000XM4 earbuds include thoughtful features for daily use. Speak-to-chat technology detects your voice and automatically lowers the volume so you can interact with others without tapping controls or removing the buds. Call quality benefits from a dual beamforming microphone array combined with a bone-conduction sensor that isolates your voice from background noise. The included wireless charging case adds grab-and-go convenience, and the sweatproof design handles workouts and commutes. As a renewed product, these earbuds have been inspected and tested to meet functional standards, offering the full WF-1000XM4 experience at a more accessible price point.
