Hi the method these things do to connect is called pairing which simply means it needs to seek the device and make communications with it, be is a mobile phone or an MP3 player.
or even a computer like an apple.
so it may take some time to function.
are you aware that this device uses a radio frequency of some 2.4 ghz the same frequency as the microwave oven and although at low power it is still cooking the meat in your head namely your brain,
so do you want a tumor later in life due to using this thing stuck in your ear.
well i don't.
