This is the earbud unit for the SONY WF-1000XM4. I am selling it because I lost the charger and can no longer charge it. Operation has been confirmed (images 11 and 12). [Set Contents] ・Earbud unit (black) with SS ear tips attached ・Ear tips (S x 1, L x 2) ← Brand new, unused ・Included USB Type-C cable ・Instruction manual x 3 ・Warranty ・Recommendation for product support registration ⭐︎I will generally not send the SS ear tips. ※ I was able to use it without any problems for about a year, but there are fine scratches and dirt on the main unit. I have included overall photos, so please check them yourself, although they may be difficult to see in the images. To reduce shipping costs, it will be shipped in simple packaging. Please understand. #SONY #Sony #WirelessEarphones
