Lenovo Bone Conduction Headphones Wireless Earphones with Microphone 【Product Description】 - Brand: Lenovo - Model Name: thinkplus - Included Items: USB charging cable, instruction manual - Type: Bone conduction earphones 【Additional Information】 These are bone conduction earphones purchased from Aliexpress. I bought them in late October for work, but my telework project ended at the end of November, so I haven't used them much and am now selling them. Operation has been confirmed. The main unit is in excellent condition with no scratches. Please note that the outer box is dented. They are more affordable than brands like SHOKZ. How about these for your first bone conduction earphones? Returns are not accepted except for initial defects. I will pack them in a plastic bag, bubble wrap, and cardboard box for shipping.
