hey its shy again! haha yes chime in.
i also asked phonak about a retailer and they referred me to the same site as you said www.hifiheadphones.co.uk
so thats where ill be getting them. maybe they can put this website at the end of the Phonak PFE review page too aside from amazon.com.
from your description of the filters, then they are just the grills/mesh covering right? hehe weird about how they can "break and need replacing in time" (earwax or physical damage aside).
yeah nice idea about buying the 012 instead. it didn't stick to my head when i read about the Perfect Bass model as having just a different filter. it always came to me as a different lower-end cheaper model because both the name and price were different. thanks again. nice recommendation and saved me some money!
