I disagree. Sure, it connects - but mulitple people have told me that they here a whirring/buzzing in the background when I talk. I double-checked this by calling my home line and sure enough, I hear the same buzz. =-/
Well, mine always made the whirring/whining noise to my recipients. I picked up another brand (cheaper actually) and this one works just fine with no complaints from recipients of my calls. For some reason, the Motorola H500 never worked correctly with my iPhone. Hope you fair better results!
