Sony’s new TWS headphones have arrived!

Sony has announced the WF-1000XM4 – the latest wireless model of the 1000X series. The WF-1000XM4 headphones take the top-of-the-line noise cancellation and audio quality to the next level. Made to suit every ear, they offer a personalized experience that adapts to any situation.

Even clearer sound, even less noise

The WF-1000XM4 provides the top noise canceling function in the class, which is now getting even better. The newly designed V1 processor they integrate offers even better noise cancellation. Specially designed by Sony, the built-in V1 processor further improves the noise canceling quality of Sony’s already recognized QN1e chip. Improved noise cancellation performance and Bluetooth® ‘System on Chip’ technology provide the industry’s highest level of noise cancellation, but also use less power than their predecessor. The WF-1000XM4 feature high performance dual microphones with noise sensor for excellent noise cancellation. With two noise detection microphones per ear – one feed-forward and one feed-back – the environmental noise is perceived and analyzed, resulting in high-precision noise cancellation.

A newly designed 6 mm guide with a 20% increase in magnet intensity also improves the noise canceling capabilities of the WF-1000XM4. Increasing the volume of the magnet and the high conformity aperture give improved performance at low frequencies and enhance noise cancellation by creating a high precision cancellation signal in the low frequency range. The newly developed Earbud Tips for noise isolation offer an improved fit to the WF-1000XM4. The new ends of the handset are made of a unique polyurethane foam material that is soft and elastic, which maximizes the contact surface between the end of the earphone and the ear. This eliminates gaps for sound insulation and noise reduction, as well as improved traction in the ear canal for a more stable fit.

Even days with stormy winds you will be completely immersed in the experience. The automatic wind noise reduction function detects when there is wind and suppresses its noise, automatically.

Excellent sound quality

The WF-1000XM4 now supports high-definition wireless audio, thanks to LDAC, Sony’s industry-leading audio encoding technology. LDAC transmits about three times more data (at a maximum transfer rate of 990 kbps) than conventional Bluetooth® audio, allowing you to enjoy high-definition audio content as close as possible to the corresponding wired audio. Thanks to the specially designed 6 mm guides, a dynamic sound is reproduced despite their small size and the high compliance aperture reproduces a rich range of bass. The built-in V1 processor also improves audio quality and reduces distortion and allows processing via LDAC encoder and DSEE Extreme ™. Using Edge-AI, DSEE Extreme ™ (Digital Sound Enhancement Engine) upgrades compressed digital music files in real time. Dynamically recognizing the instruments, musical genres, and individual elements of each song, such as vocals or breaks, restores the amplitude sound lost during compression for a richer and more complete listening experience.

An even smarter listening experience

Speak-to-Chat received positive reviews for its innovation when it first appeared on the WH-1000XM4 headphone model. The feature is now available on the WF-1000XM4 and allows you to have short conversations without removing the headset. Once you talk to someone, Speak-to-Chat automatically mutes the music and turns off the surround sound so you can have a conversation – useful if you want to keep your headset on or your hands free. Once your conversation is over, your music starts playing automatically again. Speak-to-Chat recognizes and responds to your voice. It is based on Precise Voice Pickup technology, which combines four microphones and sensors with advanced audio signal processing.

The “Quick Attention” function is available at WF-1000XM4, so if you want to hear an announcement or say something quickly, simply place your finger over the left earpiece to turn down the volume immediately and let go of the ambient sound. The WF-1000XM4 also features Adaptive Sound Control, a smart function that detects where you are and what you are doing – for example, traveling, walking or waiting – and then adjusts the surround sound settings for the perfect listening experience. You can choose Adaptive Sound Control to start recognizing places you visit often, such as your office, gym or a favorite cafe, and adjust the sound to suit the situation.

The headphones come with support for instant pause and resume music for a smooth experience. Just remove the headphones from your ears and the music stops thanks to the sensor that detects if you are wearing one or both headphones. Just put them on again and the music starts again.

Enjoy superior call quality
Hands-free calling is even better with the WF-1000XM4 thanks to Precise Voice Pickup technology. Combining Precise Voice Pickup technology with microphones and a bone conduction sensor, the WF-1000XM4 receives your voice with clarity and precision for hands-free calls. Radiation microphones are calibrated to receive only sounds from your mouth. With an improved signal-to-noise ratio, they will catch every word, even when there is a lot of noise around you. In addition, the new bone conduction sensor only receives vibrations from your voice – it does not record ambient sound – allowing even clearer speech when making calls. Noise cancellation makes your WF-1000XM4 calling experience even better as it lets you hear the person you are talking to more clearly, even in noisy situations.
