Sony WH-CH520 Wireless Headphones Bluetooth Compatible Lightweight Design (Approx. 147g) Equalizer Settings for Customizable Sound Quality via App

The headphones offer a well-balanced sound from high to low frequencies, allowing you to enjoy natural, clear vocals and instruments. Furthermore, Sony's proprietary DSEE technology compensates for high frequencies, often lost in compressed audio sources, to CD-quality sound. Compressed audio sources, such as streaming, MP3, and Bluetooth transmission codecs, are reproduced with spacious, clear sound. Compatible with the Headphones Connect app, the Equalizer allows you to customize the sound quality to your liking. Choose from eight presets, including Relaxed and Bass Boost, or customize the equalizer settings to your liking. The headphones feature smooth, wrinkle-free, low-resilience urethane foam ear pads. The soft, comfortable ear pads provide a lightweight, 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.
