Can You Hear Me Now?

This device makes it easier for hearing-aid users to go cellular. The tiny ELI plugs into the bottom of most behind-the-ear hearing aids, essentially turning them into wireless cell-phone headsets and eliminating the static that often occurs when hearing aids and mobile phones interact. A miniature microphone transmits the wearer's voice back to the phone. And for people who use in-the-ear hearing aids, there's another version of ELI that hangs on a cord around the neck.
