Sony 1000X series wireless earbuds, black, with a bonus silicone case. Functionality confirmed. - Brand: Sony - Model: WF-1000XM4 - Color: Black - Accessories: Eartips (various sizes), charging cable, instruction manual - Case: Charging case (black) Complete with the original box. A silicone case is 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. The S and L eartips are unused. I kept them in a silicone case, so they are in relatively good condition. Please refrain from purchasing if you are sensitive to imperfections or do not charge frequently. Shipping will be via Yu-Packet Post with the box disassembled. Thank you very much (*^_^*) ※ A similar item sold, but was mistakenly purchased, so I am relisting it.
