I OWN THE OLDER TYPE EXCALABUR WITH BLUE HEADPHONES. MY PROBLEM IS WHEN I PLACE THE RUBBER GASKET ON THE CORD AND THE TWIST IT ON FIRMLY TO THE BATTERY, WATER SEEMS TO GET ON BOTH SIDES OF THE RUBBER GASKET. WHEN I DETECT MY EXCAL SEEMS FINE, THEN AFTER A HALF HOUR IT MAKES A LOW TONE THAT COMES AND GOES. THIS SOUND CONTINUES NO MATTER WHAT I ADJUST. I THINK IT MAKES THIS SOUND BECAUCE OF THE WATER REACHING THE BATTERY THROUGH THE RUBBER GASKET. I MAY BE SWISTING THE CABLE END TOO TIGHT, OR POSSIBLY NEED A NEW GASKET? OR MISSING SOMETHING THAT STOPS WATER FROM ENTERING THE BATTERY AREA. THIS IS WHAT I DO, CHARGE BATTERY PLACE RUBBER GASKET ON CABLE WITH THE THREE PRONGS, TWIST THE CABLE TO THE BATTERY, I DO TWIST THIS TIGHT, TO ENSURE NO WATER GETTING IN. BUT IT STILL GETS IN. SORRY ABOUT THE CAPS, I AM AT WORK AND IN A HURRY. PLEASE HELP ME. IF I NEED NEW PARTS LET ME KNOW A PHONE NUMBER ORDER THEM. I LIVE IN MICHIGAN. THANK YOU.
