I used these for a certain period when going out, and have since stored them at home. Operation has been confirmed (Bluetooth connection, charging, and sound output all work without issue). The original ear tips are missing, so I will include unused ear tips as a replacement, as well as SpinFit CP360 ear tips for fully wireless earphones, sizes S/M and M/L (likely). Some of the SpinFit ear tips have been used for trial fitting. Please consider these as a bonus. The USB-C charging cable may not be the original accessory. Please check the detailed condition in the photos. 【Product Description】 These are fully wireless earphones with active noise canceling (ANC) function and are waterproof and dustproof (IP57). The compact design provides a comfortable fit, making them suitable for sports, commuting, and other situations. Sound customization is also possible through app integration. 【Shipping Method】 Will be shipped via Yu-Packet Plus or Takkyubin Compact. 【Regarding Purchase】 ・We do not accept price negotiations. (If a price negotiation is requested even though this is stated, the price will be temporarily increased.) ・Please consider purchasing only if you understand that this is a used item. ・Returns and exchanges are not accepted to prevent product substitution.
