Sony's wireless noise-canceling headphones, the "WH-XB900N." This is a model from the EXTRA BASS series, which offers overwhelming bass. ■ Included Items (as shown in the photos) • Headphones (Blue) • Dedicated carrying pouch • Audio cable for wired listening × 2 (※One is for spare use or convenient use depending on the situation) ※The outer box and USB charging cable are not included. ■ Condition of the Item • Operation confirmed. Bluetooth connection, noise canceling, and button operations are all good. • There are wrinkles and signs of use on the ear pads (please check the photos). There are no tears. • The headband and housing are in relatively clean condition. ■ Shipping • As this is precision equipment, it will be placed in the pouch, carefully wrapped with cushioning material (bubble wrap), and shipped via Mercari delivery. Immediate purchase is welcome. Due to the completeness of the included items, I am not currently considering a significant price reduction. Thank you.
