Sony Bluetooth wireless headphones with noise-canceling function. I haven't used these much since I bought them, and they've been stored in their carrying case. I'm selling them because I don't use them. Functionality has been confirmed, and there are no issues. Accessories include the carrying case, a USB charging cable, and a stereo mini-cable. - Brand: SONY - Color: Black/Blue - Features: Wireless, Bluetooth connection, Noise-canceling - Controls: Volume adjustment, Play/Pause button - Charging port: USB-B - Earpad material: Synthetic leather - Power button: Yes Thank you for looking.
