This product, which is worn on the ear like a coil of mosquito incense, is actually a Bluetooth headphone. The large round shape in the middle of the mosquito incense is the phone switch, and when there is an incoming call, ripples will appear on this round shape. The tail of the mosquito incense is a small round shape, which is actually the microphone. The other day, I got the idea from a banana-shaped Bluetooth headphone: why not design a Bluetooth headphone that can be worn like an earring? Combining earrings with Bluetooth headphones, they could be used for making calls as well as serve as accessories, surely appealing to women and becoming a trendy fashion. In the future, there would be no need to hold the mobile phone while calling. It turns out that similar conceptual designs already exist. Although this design doesn't quite look like an earring, it's still a pretty good design.
