With a well-balanced sound from high to low frequencies, you can enjoy natural, clear vocals and instruments. Furthermore, Sony's proprietary DSEE technology compensates for high frequencies often lost in compressed audio sources, bringing them to CD-quality sound. Compressed audio sources, such as streaming, MP3, and Bluetooth transmission codecs, are reproduced with spacious, clear sound. The dedicated app allows you to customize the sound quality using the Equalizer function. Choose from eight presets, including Relaxed and Bass Boost, or customize the equalizer settings to your liking. The ear pads feature smooth, wrinkle-free, low-resilience urethane foam. The soft, comfortable ear pads provide a lightweight and comfortable fit. Enjoy up to 50 hours of music playback*. Plus, quick charging allows for approximately 1.5 hours of playback with a 3-minute charge (approximately 5.5 hours with a 10-minute charge*). Hands-free calling* is possible with smartphones, iPhones, and PCs. * Your smartphone, iPhone, or PC must be equipped with Bluetooth and support HFP or HSP. Depending on your software and environment, it may not be compatible.
