This headset seemed great at first.  Now, people can't hear me when I use it.  They say I'm breaking up.  Adjusting the volume doesn't help.  Finally, when I disconnect the BT350, my call becomes crystal clear.  Also, this headset always turns itself on when it's in my purse and then dials people.  That is a problem of draining the battery and of nusance calls.  Unfortunately, I've had just past the 1 year warranty period so I'll probably have to buy a different one.
