Sony WH-CH520 - Blue Bluetooth Headphones

Enjoy great sound quality all day long. The Sony WH-CH520 headphones, with up to 50 hours of battery life, stable connectivity, and improved call performance, meet the demands of your daily life.

Features:

• A listening experience designed for you: Digital Sound Enhancement Engine (DSEE) restores harmonic tones and intensity lost during normal music compression to deliver a more authentic performance. You can even customize the music to your liking with the equalizer settings in the Sony | Headphones Connect app for a personalized listening experience.
• Battery for several days: With up to 50 hours of battery life, you can listen to your favorite music without worrying about running out of charge. And if the headphones' battery is running low, a 3-minute quick charge can give you 1.5 hours of listening time.
• Clear calls: The built-in microphone allows hands-free calls, as well as joining an online class or work meeting.
• Multipoint connectivity: These Bluetooth® headphones can use this technology to pair with two devices simultaneously. This way, when a call comes in, the headphones will know which device is ringing and automatically connect to the correct one.
• Designed for all-day use: The design is not only stylish but also user-friendly. The lightweight structure and swivel ear cups put on and take off smoothly, while the adjustable headband, padding, and soft ear cushions provide comfort all day long.
• Sustainability as a goal: Our products are not only stylish but also environmentally friendly. The WH-CH520 headphones are made with recycled plastic*. Additionally, the individual packaging contains no plastic**. These headphones reflect Sony's commitment to reducing the impact of our products and practices. *Recycled plastic is used in multiple parts of the headphones' body (subject to change). **Adhesive and coating materials are excluded.
