Mobile phone headphone connection is divided into wired headphone and wireless Bluetooth headphone two, the plug of the wired headphone is 3.5mm headphone plug, you need the phone with the headphone jack, because the current production of mobile phones do not have 3.5mm headphone jack, you need to use the adapter.
The other is Bluetooth connection. After turning on the headset, switch to the state to be connected. Open the Bluetooth menu of the mobile phone to search for the headset and select connection.
