Changing small bluetooth headphones for a phone, tablet and more

I bring to your attention small bluetooth headphones for a phone tablet and not only is the condition good, but there are small life marks on the case; I bought it and hardly used it; it was lying there, so there are abrasions; it was dragged from place to place; put the battery in because the fast chargers will quickly cover them, I change them to 2 external USB hard drives, watch movies at the dacha via USB on the TV, or I change them to an external drive for a netbook so that the power is exactly 220 volts from an external 12 volt power supply, like the model and brand in the photo does not matter for all questions you are interested in, respectfully please write to Olkh in a personal message since the phone is not available due to a sick child, write, be interested, ask, I will answer if possible to everyone, I look forward to your options and suggestions, sincerely, Mikhail
