Summary: Has 3 channels on the base charger and the ear phones automatically switch to that channel when you flip the switch on the ear phones. That is just the start. When you hang the head phones onto the base charger, the head phones automatically switch off and the charger switches on.
Excerpt: Ordered a pair, worked great for one week, then one ear piece stopped working. Ordered a 2nd pair and they didn't work on either side right out of the box. Where are all these good reviews coming from?? I give up.
