This is the black Earfun Air Pro 4. I purchased it around last summer. I am selling it because I bought other wireless earbuds and no longer need these. I have confirmed that it works without any problems. The seal on the surface of the box has been peeled off, so the product image is slightly peeled and sticky. The main unit case has a few scratches, and the ear tip case and instruction manual have some folds. I only tried the largest size ear tips once to test the fit, and I used the ones that came with the product from the beginning until the end, so the other ear tips are unused. The charger is also unused. All accessories are included. I will clean it again before shipping. I am not currently considering price negotiations.
