手机能否当作蓝牙耳机使用？
Can mobile phones be used as Bluetooth headsets?
只要手机自带蓝牙设备，且蓝牙耳机的版本高于手机蓝牙版本，就能实现连接使用。具体连接方法如下：
As long as the phone has built-in Bluetooth and the Bluetooth headset version is higher than the phone's Bluetooth version, they can be connected. The specific connection methods are as follows:
1. 首次配对连接
1. First-time pairing connection
耳机开机后会有语音提示自动搜索设备，此时需要打开手机蓝牙功能。
The headset will prompt voice search for devices when powered on, at which time you need to turn on the phone's Bluetooth function.
2. 设备搜索与连接
2. Device search and connection
手机开启可检测性后，搜索附近的蓝牙信号，找到耳机型号点击连接。如需密码，默认通常是0000。
After enabling detectability on the phone, search for nearby Bluetooth signals, find the headset model and click to connect. If a password is required, the default is usually 0000.
3. 更换配对设备
3. Changing paired devices
在耳机关机状态下长按多功能键8秒，直到红绿灯交替闪烁，即可进入配对模式。
Press and hold the multifunction button for 8 seconds when the headset is off until the red and green lights flash alternately to enter pairing mode.
4. 自动重连
4. Automatic reconnection
成功配对后，下次开机时蓝色指示灯缓慢闪烁表示自动连接成功，来电时按多功能键即可接听。
After successful pairing, the blue light will flash slowly when powered on next time indicating successful automatic connection. Press the multifunction button to answer calls.
温馨提示：不同品牌蓝牙耳机操作可能略有差异，请参考产品说明书。
