The ShareMe button is marked with an S in a circle, and must be clicked briefly. Do not keep the button pressed. Step 4 may go wrong if not done correctly. Please make sure that you have the second Everest 300 turned off. Now press AND HOLD the on/off button for about 15 seconds. The LED must switch to white/red blinking to indicate that it is actually in BT pairing mode. Now simply wait until the two headphones have communicated with each other, and established the BT connection. The white led below the S buttons will light constantly on both headphones when the ShareMe connection is ready. Now you just begin music play on the source, and both headphones will play.
