Dual device pairing is one of the most useful earbud features
Taking a call from one phone and listening music on another? Use dual device pairing feature on your earbud. It will allow the multitasking convenience where you don’t need to disconnect and re-connect to each phone.
I have used this feature, usually when any call comes on my phone, the earbuds fail to understand which input it should consider. As such, my audio often stops playing.
