For sale: SONY Wireless Noise Canceling Earbuds WF-C700N Purchased in January 2024. I enjoy gadgets and own multiple pairs of earphones, so these were used as a secondary pair. Therefore, the usage frequency was low, and I took care in handling and storing them, so I don't feel much battery degradation. They were used and stored in a smoke-free and pet-free environment. [Operation] - Operation confirmed - Bluetooth connection and noise canceling both work without problems [Condition] - Overall, there are no major scratches or stains, but there is some wear on the exterior of the case due to being carried in a bag. - There are no noticeable scratches or cracks. - Please check the condition in the images. [Earpieces] - S / M / L size earpieces are included. - Currently, the S size is attached and will be shipped. - The M size earpiece has some white spot-like discoloration (unknown cause, possibly chlorine marks from when I washed the earpieces and didn't dry them completely? The marks don't come off even when wiped.) They are usable, but if you are concerned, you can discard them. [Accessories] - Earphone body - Charging case - Cord (unused) - Earpieces (S / M / L) - Outer box * Please purchase only if you understand the condition as a used item. We will perform a simple cleaning before shipping. If you have any questions, please feel free to comment before purchasing. Thank you.
