★ I have taken photos of all the items I will be sending. See the second and third photos. The original box can sell for over 2000 yen even if it's empty, so I can include it for an additional 1000 yen if you want it. Since it has been replaced, the serial number on the original box will not match the serial number on the main unit. Reference: The last four photos are from someone who opened a replacement AirPods Max they received online. I have added screenshots confirming the serial number in Apple's "Support" app and on Apple's warranty check website. I believe it will increase your trust if you confirm that the serial number on the box matches the serial number on the device. The serial number is: H0YN93FNP3W9 ↑ This is the number 0 (zero). Please note that when you copy the text from the images, the 0 (zero) is sometimes read as O (oh). Apple AirPods Max Space Gray with Black Headband ★ I purchased a brand new AirPods Max Space Gray, but it was replaced because I hadn't used it for a long time. I removed the ear cushions and the Smart Case and only gave the main unit to the delivery company, so both of those items, along with everything else, are brand new. ★ As proof of authenticity, the serial number on the box can be found on the inside of the left ear cushion of the main unit, and also when connected on macOS, iOS, or iPadOS. If the item is opened and returned, the value will be reduced by more than half, so I hope you will trust my rating and the comments in the feedback section. Recently, there was a problem where the cardboard box had a hole and the product package was damaged, and there is a possibility that the buyer blamed the delivery company for the damage they caused themselves, so I will carefully pack and ship the item while recording a video to keep evidence. ★ These are genuine Apple headphones and are very popular. They are highly rated worldwide for their functionality and sound quality. The reason a new AirPods Max with updated sound quality hasn't been released for several years is because the sound quality is already perfected.
