Wireless earphones, Earfun Pro 3. Multi-point connection possible with smartphones and PCs. The noise cancellation is also quite excellent, and I've been using them for two years, enjoying them comfortably even on public transport. However, the Bluetooth connection has stopped working, so I'm selling them as junk. They seem to be in pairing mode (earphones blinking blue rapidly), but they are not recognized by devices such as smartphones. It seems they are charging from the case (red light when stored in the earphones). Unfortunately, they cannot be used as earphones as they are. Please consider them for parts for those who know about them, or for using the charging case only.
