JOYROOM Bluetooth Earphones Ear-hook type Purchased in 2018. Used a few times, but it didn't suit my needs, and it's been stored in a drawer for a long time. I checked the functionality. It works without any problems. There is a two-pronged charger. I have uploaded a photo of the back of the package with the specifications. =============================================== 【Bluetooth 5.0 Enhanced Version】 Bluetooth Earphones, Both Ears, High Sound Quality, Completely Wireless Earphones, Ear-hook Type, Automatic Pairing, IPX5 Waterproof, Bluetooth Earphones with Microphone, Lightweight, Siri Compatible, Bluetooth Headphones, Hands-free Calling, CVC6.0 Noise Canceling, Compatible with iPhone & Android
