The complete individual lengths are published by the separate Japanese maker accessory list.14Maker product pagesony.jp/headphone/products/ULT_WEARRead 8 October 2026The exact maker supplied-accessory list states a headphone cable approximately 1.2 m long and a USB-A to USB-C cable approximately 20 cm long. The original guide separately confirms one of each. This preserves the supplied charging-cable length without adopting optional aftermarket cables.
