My Life dot 2s came right out of the box and connected to my phone. Upon turning on noice cancellation, slight movement would allow me to hear a rattling in the earbuds, as if something is loose. What do I do about this
You will need to make sure you have the right fit of the ear buds.
You may need to change the earwings and tips to get a good fit.
Unsure about the rattle sound. Could it be the microphones rubbing on your ear or maybe ear hairs hitting the mics.
