Compared with wired headphones, the biggest difference between Apple's third generation Bluetooth headphones is the connection method and the cable. Bluetooth headphones use Bluetooth technology to connect to the device, avoiding the restrictions brought by the cable, so that users can move freely. The wired headset needs to be connected to the device through the wire, and there are problems such as wire entanglement and limitation. In addition, Apple's third generation Bluetooth headset also supports touch operation, automatic switching and other functions, so that users can use more convenient. However, Bluetooth headphones also have problems such as unstable signals and insufficient power, and the price is higher than that of wired headphones. Taken together, users can choose their own headphones according to their needs and budgets.
