Mobile phones can stream videos, play songs, podcasts, audio books, even pay for your dinner bill. So why is it still so hard to hear the person on the other line?
Science and technology writer Jeff Hecht says he doesn’t even own a smart phone.
“I don't have a smartphone. I do have a dumb phone,” Hecht says, “The dumb phone does have one advantage — it's a flip phone. So there's a logical place to hold it to my mouth. One side's on my ear, one side's on my mouth I can feel where it is so it doesn't just drift off.”
