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 headphone and audio source line is 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.
In other words, compared with traditional “wireless headphones”, the connection of true wireless headphones is not only the signal transmission between the headphones and the signal transmitting device but also the wireless connection between the main and auxiliary headphones. Compared with traditional “wireless earphones”, true wireless earphones have a more complicated structure, higher transmission requirements, and higher power consumption. These elements will also have a more obvious impact on the sound effect. The general phenomenon is that the sound quality of truly wireless earphones is slightly lower than that of Bluetooth earphones of the same price. Difference.
