If you need to use wired headphones and can't use the 3,5mm jack on your BV8000, you can try this, which I tested and works:
1) You need to get a USB sound adapter (as cheap as $1 on Aliexpress). Something like this: https://www.aliexpress.com/store/product/Hot-sale-Audio-Adapter-3D-Sound-card-5-1-USB-To-3-5mm-mic-headphone-Jack/2711003_32886524426.html
2) Connect the sound adapter to the phone, using the usb host cable.
3) Connect the headphones to the sound adapter. If you also need to use the microphone on the headphones, you will also need something like this: www.aliexpress.com/store/product/New-3-5-mm-Black-Headphone-Earphone-Audio-Cable-Micphone-Y-Splitter-Adapter-1-Female-to/1988229_32826339576.html
That, or do what I do and use USB headphones with the Type C - USB adapter that comes with the phone.
