Sony True Wireless noise cancellation Lightweight and compact design Sound quality upscaling function Up to hours of continuous music playback IPX4

By optimally controlling the microphones mounted on the left and right sides, it precisely generates out-of-phase sound that cancels out noise. With high noise cancellation, you can immerse yourself in music even in noisy environments such as trains and buses, or in environments with many people such as streets and cafes. In addition, it also features natural ambient sound passthrough. These headphones offer a well-balanced sound from high to low frequencies, allowing you to enjoy natural and clear vocals and instrument sounds in particular. Furthermore, Sony's proprietary "DSEE" technology (*) compensates for the high frequencies that tend to be lost in compressed audio sources, restoring them to CD quality within the headphones. This allows for the playback of compressed audio sources such as streaming, MP3, and Bluetooth transmission codecs with a spacious and high-quality sound. * DSEE can be enabled through the "Headphones Connect" app. The headphones and case are designed to be compact. By minimizing the protrusion from the ear, they offer a comfortable fit and a smart appearance. They provide a comfortable fit that reduces fatigue even during long listening sessions. Furthermore, you can choose from trendy muted colors such as lavender and sage green, as well as basic white and black, to match your fashion style. With noise cancellation ON, the headphones offer up to 7.5 hours of use on their own, and a total of up to 15 hours with the charging case (*1). They also support quick charging, providing 60 minutes of playback with just 10 minutes of charging (*2).
