I had an email from K & S Distribution who are the distributors here in the UK for Phonak, after I sent an email to Phonak in Switzerland and this is what they said " The short answer is yes, Phonak are due to bring out a new product, a multi-balanced armature Earphone. I believe it's scheduled for release around April 2011 but other than that the details are closely guarded!"
So I suppose we just have to wait and see.
