I got my PFE012 about a week ago and they really impress me. But I've been poisoning myself on the PFE232s. This review really helps. I think I'll go ahead and get myself one. I was considering them against the Westone 4 but I think that liking the sound signature and comfort of the PFE series, I think is the one for me.
I have no experience with the Westone's or other Phonak's. I'm sure the 012's have similar sound signatures. But from what i've read the 232's have a more rich, detailed and open sound. You only have them a week, so i'm sure you can return it for the 232's. And if you don't like them (hard to imagine) you can return it anyway.
