【Excellent Condition】Sony Wireless Headphones WH-CH520 Lightweight Approx. 147g

Thank you for looking.

It was very good, but I can't wear it to work, so
I've kept it in a drawer, barely used.

Just in case, I've uploaded as many photos as possible from various angles, so please check the condition.

Please download the instruction manual from the internet.
