Used Sony WF-1000XM4 Noise Cancelling Earbuds. PLEASE NOTE: Battery life is not great, especially the left earbud only has about 15 minutes of usable life. These are great earbuds, the noise cancellation is top of the line. Someone with technical ability could buy a battery replacement kit and make these excellent again. Comes with original packaging and materials, including different sizes for the earbuds. These is in great condition with no scratches, dents, or other blemishes.
