IV. bluetooth headset problem
The main thing is actually the Bluetooth headset itself. Especially the design of the headphone cavity structure is unreasonable. If you've learned physics, sound in the process of transmission, if encountered obstacles, will inevitably produce echoes, structural design unreasonable, will lead to echo too big, so that people can obviously feel out, especially Bluetooth headset microphone design and handset distance closer, it is easier to produce echoes. If you disconnect the Bluetooth headset, you can eliminate the echo, connect the Bluetooth headset and Echo, then this is the problem of the headset itself.
