I have no idea.  It doesn't look like there is any residue or anything on the housings, so I'm not sure how they were on there or if they are replaceable.  I guess I'll have to contact PAnny.   My biggest concern is if I can ruin them with out the filters.

Thanks Marcus!  So you are suggesting what you think others will suggest?      Are those the Panasonics?   My budget is capped at $200, but if there is something comparable at a lower price I'll pick them up (just saying I don't NEED to buy a name....long as they perform that's all that...
