Change the audio out jack to headphones PLUS mike (iPhone headset)?
The device has an audio jack - but this connects only audio out for headphones, I still have to use the - very good - Jabra microphone. But this picks up a LOT of ambient noise.
I would like to plug in my iPhone headset and use also its microphone.
Can I change the audio jack to one which when a plug is inserted it switches of the Jabra internal microphone and instead uses headphones and microphone of the iPhone headset?
Or could I add a second jack?
