With headphones turned off, & within 1 meter (3 feet) of music device, press & hold center key for more than 4 seconds until you see alternating red/green flashing of the status indicator and a voice prompt saying “Searching for your music device”. 2. On your phone/music device, turn Bluetooth on & have it search for Bluetooth devices (see instructions in the phone/music device manual for details). 3. Check for “X2” and select (enter passcode 0000 if prompted). 4. X2 voice prompt will say “headphones connected”. 5. If the pairing is not successful, switch off headphones by pushing the center key for more than 4 seconds and repeat the steps outlined above.<br><br><b>HOW DO I CHARGE MY HEADPHONES? </b><br>Analyze the primary power and charging source. We find computers to be a great, safe method. Anything that is less than 1 AMP is safe and recommended. Over charging your battery will quickly reduce the life of the headset, so along with monitoring the power supply, try to keep your charge time limited to 2.5 hours. To get the most out of your battery it is recommended to charge the buds when the low battery status is indicated.
