Here's a video showing how to connect the LC-B41 with two phones: https://www.amazon.com/vdp/06dbf5b3080a4907ac5382afdfed8165

Step 1: Turn on the earpiece and open Bluetooth function on phone A, search the earpiece and connect it, then close the connection on phone A;

Step 2: Connect Phone B with the earpiece as the same as step 1;

Step 3: Keep Phone B connecting and then re-connect Phone A;

Make sure the two devices are successfully connected with the earpiece at the same time, and you can make/receive phone calls from both. Auto connection will be default when you use it next time.

Note: Connect two mobile phones at the same time, only one mobile phone can work, the other is in standby mode. That is mean it can't play two phone's sound at the same time.
