Coincidentally, I also own a pair of the Oticon Opn 1, and I pretty much agree with the blog piece. My biggest gripe is how short the battery life is when on bluetooth. And my 2nd biggest gripe is that there is no way to 'lock' the Opn into Loop mode when wearing headphones. If the headphones move a bit, the Opn no longer detects the magnetic coil and disengages loop mode. I would like to be able to use the iPhone app to lock them into loop mode until I manually change the mode...
Oh, and yeah, I ALWAYS take my hearing aids out when I am at the barber! The idea of leaving them in... shudder!!
