Thank you for viewing. I am selling these earphones because I recently purchased a new pair. Brand: SONY Model Name: WF-1000XM3 Features: Noise Canceling Bluetooth compatible Google Assistant compatible Alexa compatible Other Color: Black Charging Case: Yes Used for approximately 5 years. All accessories are included, such as ear tips, instruction manual, and USB cable. Only one ear tip has been used, the others are unused. Purchased at Bic Camera (receipt not included). ＜Product Condition＞ As with many other sellers, the right earbud's battery drains a bit faster. When worn, it seems to run out of battery (without being returned to the charging case) in about 60 minutes or less. It drains even faster when using noise canceling. The charging case is used, but I don't charge it frequently. I can use it for over a week without charging. So I don't think there's a problem, but I haven't compared it to others. The charging case has normal wear and tear, which is difficult to see in the photos. Other than that, as far as I can tell, there are no particular problems, but I may have overlooked something. If you have any concerns, please comment. The above is my subjective assessment, but I hope it helps. In preparation for listing, I wiped it with an alcohol wipe, but If you are uncomfortable with used items, including the product condition, please refrain from purchasing.
