Query: Charging Problems

I bought this product and it worked well for a month or so. Then the headset would not take a charge. I returned them and they sent me a new unit. Two months later the new unit will not take a charge. I am sending them back now. The unit sounds good when working and the cordless feature is great for the gym but the battery life on the Ipod is cut to about 3 hours maximum with this unit. I am constantly chargeing my Ipod. I have read other reviews about moisture on the headset. Mine get soaked at the gym but so far customer service has not said a work about it. they are good to deal with but you have the shipping costs and the time lag to deal with. All in all I think it is easier to put up with the cord and have you unit last longer than it is to fool around with these especially at the cost.
