Maybe some friends still feel puzzled. What is the difference between this "Bluetooth headset" and "Wireless headset"? Many friends will say that many Bluetooth headsets are wireless, but traditional in-ear Bluetooth headsets still have cables on both sides for audio signal transmission. In other words, the two sides of the in-ear Bluetooth headset with a cable can work at the same time, just like a Bluetooth speaker, the in-ear Bluetooth headset can be transmitted through the cable, so that the two ears can emit sound stably and synchronously, but this is only The earphone and audio source line are omitted. True wireless bluetooth earphones will have the difference between the main earphone and the sub earphone. When connecting, you need to connect the transmitting device (mobile phone, tablet computer, music player with Bluetooth output, etc.) to the main earphone first, and then connect with the auxiliary earphone after confirming the connection. It can work normally after the connection is completed.
