Not all models have this function, but if yours should, we‘re here to help! Here is the step-by-step guide: pair your headphones with your first device (say it‘s a smartphone), switch the device off, and switch off the headphones. Next, repeat the same process for the second device (say it‘s another smartphone). Once both smartphones are paired with the headphones, turn your first smartphone back on, turn on the “Bluetooth” feature, and select your model from the list of available devices – ‘voila’, both of your smartphones are now paired with your headphones!
