First, you need to determine whether the headset supports playing music; if so, connect the mobile phone to a Bluetooth device. Just use the software to play music normally.
The method is as follows:
1. There is a button operation panel on the headset cord. The plus sign is the volume key. Click once to increase the volume. Press and hold for the next song. The minus sign also means that you can click to turn down the volume, and press and hold for one second to return to the previous song. The middle one is the playback pause button. You can answer and hang up calls on a stand-alone device. Press and hold for one second to reject incoming calls.
2. When the battery of the headset is low, it will have a voice prompt that the battery is low, please charge. When you hear the voice prompt, it means your battery power is below 10%. There is a small opening on the side of the operation panel, which opens into the charging port.
3. Finally, there is a light indicator on this headset. If it is charging, it will turn orange. When the battery is fully charged, the light will turn white. The white light will also turn on during Bluetooth operation. An orange light will illuminate when the battery is low.
Extended information
Wireless Bluetooth headsets include Bluetooth headsets and infrared headsets. Bluetooth headsets apply Bluetooth technology to hands-free headsets, allowing users to avoid annoying wires. Feel free to talk in a variety of ways. Since the advent of Bluetooth headsets, they have been a good tool for mobile business people to improve efficiency.
Bluetooth was initially developed by six manufacturers including Ericsson, Nokia, IBM, Intel, Toshiba, and CEIEC. It is a communication interface for short-distance wireless transmission. The basic communication distance is about 10 meters. The rate is about 721kbps, working in the 2.4GHz frequency band, supporting one-to-many data transmission and voice communication.
Because Bluetooth is not designed to carry large traffic loads, it is not a suitable replacement for a LAN or WAN. As the name suggests, Bluetooth headsets are headsets with the above-mentioned Bluetooth function. They are now mostly used to communicate with mobile phones with Bluetooth function.
