Functionality confirmed. - Brand: Sony - Model: WF-1000XM4 - Color: Black - Accessories: Eartips (various sizes), charging cable, instruction manual - Case: Charging case (black) Complete with original box. Silicone case included as a bonus. Thank you for viewing. Sony Model Name: WF-1000XM4 Other Features: Noise canceling Functionality confirmed. Used for commuting for about 3 years, so the battery life is somewhat diminished. The right earbud's battery life is particularly reduced. Recommended for those who charge frequently or use them for short periods. S and L size eartips are unused. They are in relatively good condition as they were kept in a silicone case. Please refrain from purchasing if you are overly concerned about condition or do not charge frequently. Shipping will be via Yu-Packet Post with the box disassembled. Thank you. (*^_^*)
