I use only one, I put the left bud in the right ear and turn the stem up, lock it under the fold there. It stays great, even in a call. Or jogging
#3 How is this on phone calls and the background noise while on a call?
Excellent in my experience. To test, I called a number and left a voicemail, and then listen to it.
#4 How many phones/devices can these ear buds be paired to? thank you
The Life P2 Mini don't support multi-point pairing, the earbuds can only be paired to one device.
#5 How do these differ from the life p2 true? does it have cvc 8.0 noise reduction also?
The Life P2 Mini has touch control and 3 EQ mode compared to Life P2 but both Life P2 and P2 Mini don't have ANC.
#6 Does this have adjustable EQ modes on the Soundcore app?
This model does not use a phone app (one of the reasons I preferred it as it was not spying on my choices) but it does have three EQ modes that you can adjust by tapping on the ear bud when you are wearing them.
