1. Type-c interface transfer. This should be the easiest, quickest and cheapest way.

Xiaomi 6 is also the latest reversible Type-c interface, so you only need a Type-c to 3.5mm audio port data cable

That’s it.

2. Change to a Bluetooth headset.

Bluetooth headsets should be the most convenient. You can change it to any interface. Anyway, you don’t need to use a data cable to connect.

After turning on Bluetooth on your phone, pair it with the headset and you can use it directly. Generally, Bluetooth can support transmission within a range of about 10 meters.
