ONE more milestone for me today! I had to return to my audi to have the custom molded silicone tips REMOVED from my new Phonak Life aids. They were just excruciatingly painful to wear. 
She put the run-of-the-mill power double-dome tips on these receivers and … I couldn’t wait to get home, do a good workout, then JUMP IN THE SHOWER with these aids on! WooOoOoOoOOOO! They got a good soaking, and annoyingly, the dingle-dangle behind my ear kept flopping forward like a big KIDNEY bean on a string! Argh. Since I no longer have the super snug custom molds in, I had a moment of panic wondering if the dang aids would fall ot of my ears and wash down the drain. But they didn’t fall out! I just kept pushing them back behind my ears and tried not to bend my head TOO far forward.
Got out of the shower, patted the aids down, dropped 'em in my ReDux dryer, and to my amazement, in just under 15 min, some 4.2uL of moisture was removed. That is actually a BIT less than the amount the ReDux removed after I’d showered wearing the custom mold tips in my ear just last week.
So two pieces of good news here: 1.) Phonak Life aids appear to be fairly waterproof, and 2.) the ReDux dryer gives me that extra edge of confidence that I’m not destroying a brand new pair of aids. 
I’ve now dunked the Phonak Life aids in two showers with ZERO degradation of sound quality or performance at all during or after the shower. Could this be my watersport aid DREAM come true!?!!
