Thank you for viewing. I received this as a gift, but I don't feel I need it, so I'd like to sell it. I have opened it and charged it to confirm its performance. (No issues, and the ear tips have been disinfected.) It comes with the main unit, charger, ear tips, a case for the main unit, a cleaning brush, and the instruction manual. 【Small and Lightweight, Comfortable to Wear】The main unit weighs only 6g, putting less strain on the ears, and providing a comfortable fit even for extended use. 【For Both Left and Right Ears】The ear wire uses a 360-degree rotating flexible cord, allowing it to be worn on either the left or right ear. It fits behind the ear, securing it in place and eliminating the worry of it falling out. 【Volume Control and Sound Quality Switching Function】The dial can be turned up and down to adjust the volume in 4 steps, and can be used for TV audio, conversations, music appreciation, etc. 【Clear Sound Quality, for Seniors】It makes the incoming sound softer and clearer. It achieves a perfect balance of high sound quality and noise suppression.
