ear plugs today.

I don't want to get anyones hopes up. Although,

I'm prolly setting

myself up for a big disappointment. The frequency response curve of

these devices are in the ballpark for what I think I need. On the

Knowles website it looks like an odd fabric type filter so it may not

be so easy to design around a desired responce.
