Sony WH-CH520 Wireless Headphones Bluetooth On-Ear Headset with Microphone, Blue New

Active Noise Cancelling (ANC) /Transparent Mode: Professional advanced noise cancellation silences up to 90% of machine noise. Cancels noise from aircraft, subways, cars, and crowds, allowing you to focus on your task. "Transparent Mode" allows you to hear and interact with the sounds around you while wearing headphones. This feature lets in ambient noise, so you can easily hear announcements on an airplane or subway, or listen to what's happening around you without removing the headphones. The sensitive buttons control makes it easy to switch between this mode and Active Noise Cancellation (ANC). Up to 65 hours of playtime: Enjoy up to 40 hours of music in noise cancelling mode, or extend the playtime to 65 hours in standard mode. A quick 5-minute charge gives you 4 hours of listening. Note: If you are not using the headphones in Bluetooth mode, please turn off ANC to conserve power. Premium sound quality: The 45mm drivers reproduce a full range of frequencies, providing deep, powerful, and immersive sound at any volume.
