These headphones, equipped with noise-canceling technology, are among the lightest at 192g, making them comfortable to wear for extended periods. I received them as a gift and used them a few times, but I'm selling them because I don't use them. Color: White Features: Noise-canceling & Ambient Sound Mode The battery allows for up to 50 hours of continuous playback. Also, a 3-minute charge provides 1 hour of playback. Price negotiable. Feel free to comment if you have any questions. Thank you for looking. Sony Model Name: WH-CH720N
