"Anonymous shipping, instant purchase OK, ships within 24 hours in principle" This is the Asuna Ver., a collaboration model of the "WF-1000XM4," a famous noise-canceling wireless earphone from SONY, with "Sword Art Online (SAO)." The color is black, and it's a set of the main unit and charging case. Both the left and right earphones have been replaced with new genuine Z55H batteries (unused after replacement). This is a used item, confirmed to be working. While I don't see any major scratches, it is a used product with minor scratches, so please refrain from purchasing if you are overly concerned about the condition. Everything shown in the first product image is included in the sale. There are no smokers or pets in my family. ■ Contents ・WF-1000XM4 "Sword Art Online" Asuna Model 　Earphone body: Right ear, Left ear 　Color: Black 　Main unit software: Ver. 2.1.0 (latest version at this time) ・Charging case "Sword Art Online" Asuna Model 　Color: Black #WF-1000XM4 #SwordArtOnline #SAO #Asuna Sony Model Name...WF-1000XM4 Other features...Noise canceling
