Where some IEMs are one-size-fits-all, it seems that the 1602s are one-size-fits-the-few. I guess that is consistent with the FAD 'out-there' ethos.
I have huge ears, both the canal and also the entire auricula. I am cautiously optimistic that the PFIX is going to slot right in and look a lot like on that model. I however will not look a lot like that model.
