It happened. They failed the other day. the same problems as stated with the older S9's. So I am getting warranty replacements from Motorola.
I am kinda bummed. Like I have stated before I had thought they had fixed the sweat problem. I have noticed something new. I believe that the sweat is actually getting into the headphones through the speaker holes.
This time they failed only after I blew into the holes after a workout. I saw something in them and I tried to blow it out. They were sweaty and the second I did that the volume down started going repeatly. and started beeping and not responding.
So there you have it. I am going to try something I read about putting a water resistant/repellant on them. I remember I use to put somthing on my old car distributor cap and the plug wires to keep them dry and not corrosive.
wish me luck
P.S. still have my trusty BlueTrek ST1's so I am not totally out of luck.
