I have these:
- 3x car handsfree - NOT android auto
- Plantronics headset
- 2x Sony headphones
- 1x Android auto
I use Plantronics whole day, but sometimes I drive the car also, so I switch the Plantronics off and use car handsfree.
Pixel has no problems switching devices in a second - while music from phone playing in the car, I switch on the Plantronics, the music will start to play in the headset in 1-2 seconds and vice versa.
NP2 is a disaster to switch devices, spent 5 minutes this morning to switch the audio to headphones when arrived by car - had to manually connect the headphones, then had to toggle “media audio” option off/on and then NP2 (spotify) shows that it is playing on headphones, but no sound at all…
