OK I spent most of last night wrestling with this X30I,,, changing sizes, of everything trying to find one that will not make hissing noises and constantly leak...
I make more calls yesterday with nothing good happening....
There was vibration sound coming from both sides of the head gear. If I pushed in on both sides the noise quit but the pressure went down
in the nose pillows - which of course makes sense
Somewhere around 3:30 ish I began moving my fingers under and around the edges of the mask and everywhere else......
Once again I turn off the resmed 11 took everything apart and put it back together with the parts I have always figured to be the ones needed for my best fit.
Turn it back on and like always nice and quiet no sound for a few minutes and then it started up again. I ran my fingers under and around the outside of the oral cushion , pulling the edge out and up and letting it snap back and magically all sound quit it function well perfectly.
I managed to get about 3 hours of sleep with out leaks......
I sue hope whatever it was is now gone forever...
I do like the mask, just not the hassle
