Same.
Huawei Bluetooth headset charging cable and Huawei mobile phone are universal, are type-C port charging cable, freebus3, Freebuds pro and FreeBus4\/4i are all.
In general, the data cable of the Bluetooth headset and the data cable of the mobile phone are common, only the power transmitted by the data cable.
The word itself is universal, but it is recommended that you use it, but the official has a choice, which may damage the data line used by its own mobile phone, mainly depending on the use time. But by itself, the impact is not huge
The data cable of the Bluetooth headset is the same as that of the mobile phone, but you have to see if the interface of the Bluetooth headset is the same as his interface, anyway, the data cable is the same, but some may be the interface is different, because there are several interfaces of the current smart phone, so the interface of the Bluetooth headset is the same as that of the previous Android version of the data cable. So charge with the data cable of the Android phone to charge, so it is better.
