Series

Every part of Sony's WF-1000XM4 headphones has been redesigned. For example, the Integrated Processor V1, specially designed by Sony to suppress more noise than ever before, a driver with improved performance,
noise-sensing microphones, and the innovative noise-isolating ear tips for an even better fit. Sony's WF-1000XM4 headphones support wireless High-Resolution Audio thanks to LDAC. With specially designed 6mm drivers, these headphones reproduce dynamic sound despite their small size, while the powerful diaphragm enables rich bass. The Integrated Processor V1 also improves sound quality and reduces distortion. Even compressed music files are upscaled, with more advanced DSEE Extreme technology providing an intense, comprehensive listening experience. Speak-to-Chat automatically pauses music and switches to ambient sound whenever you talk to someone. This means you don't have to put down the headphones with microphone if, for example, you don't have a hand free. As soon as you end the conversation, the music automatically continues. Speak-to-Chat uses an accelerometer to detect and respond to your voice. The feature is based on Precise Voice Pickup technology, which combines four microphones and sensors with advanced audio signal processing.

Precise Voice Pickup technology uses beamforming microphones and a bone conduction sensor, allowing the WF-1000XM4 wireless headphones with microphone to clearly pick up your voice during hands-free calls - at home, in a coffee shop, or wherever you are. Plus, noise reduction ensures you hear the person you're talking to more clearly, even in noisy environments. Use all day, charge in minutes. With 8 hours of battery life, you can listen to music with your Sony Bluetooth headphones throughout the workday. Charges in the charging case allow for an additional 16 hours. That's a total of 24 hours of listening pleasure on the go. Are you in a hurry? A 5-minute quick charge gets you another 60 minutes of music. The Sony | Headphones Connect app notifies you when the charging case battery level drops below 30%. Qi technology lets you charge the headphones wirelessly.
