Intelligibility can be described as good, the processing is also great. Simply fold the microphone and you connect headset and iPhone. Thanks to the Jabra app you can still make a few small adjustments.
At the beginning it is used to adjust the unit. Once you get the hang of, it is no longer a problem. Certainly more comfortable to wear than the Jabra Wave.
I am now arrived at the Jabra Stealth. Can you recommend also. :-)
