This small Gadjet I bought me for the following reason. I wanted to wirelessly use Zello while other programs are in the foreground. That works wonderfully wired. So I bought a Bluetooth headset and plug button. Unfortunately my phone thinks that this is a three-button headset. After initial difficulties (instrument sound and Microphone want to use the headset) that have been solved by software, was now just the problem, that the apparently random button triggered one of the three buttons. So it came time to the fact that it was loud, sometimes quiet, sometimes Zello was triggered. Through 4 different programs I could not turn off, circumvent or tricking the. Either bad product or completely incompatible with my phone (Samsung Galaxy Note 3). The Morse functions I have not at first been tested.
