Thank you for viewing. This is the audio-technica ATH-CKR35BT. I purchased it last year for around 7000 yen, but I no longer use it, so I am selling it. 【Design and Features】 The blue cable and the earphone body are USB rechargeable and feature convenient operation buttons, allowing for easy volume adjustment and play/pause control. 【Accessories】 A storage bag is included, making it convenient for carrying and storage. - Brand: audio-technica - Model Number: ATH-CKR35BT - Color: Blue - Accessories: Storage bag - Connector Type: USB rechargeable - Operation Buttons: Volume adjustment button, play/pause button Thank you.
