The EarFun Free Pro 3 is very popular as a cost-effective earphone! I used it for about a year, but I am selling it because I bought another pair of earphones. I had no problems with malfunctions or defects while using it! I will clean and disinfect it before shipping! It comes with a dedicated case, so you can use it as is! * Due to the material of the dedicated case, there may be small dust particles. * The top half of the case is attached to the main body with double-sided tape. Thank you for your consideration!
