SPECIAL MENTION: Phonak‘s Roger On wireless microphone (from $1,200) streams audio from afar into most modern hearing aids and cochlear implants, making it easier to isolate someone who’s talking in a noisy social gathering or speaking at a lectern. Attachments let it transmit audio from a TV, computer or other audio source. —Don Steinberg

Correction Nov, 10

The original version of this story misstated the microphone’s starting price. It starts at $1,200, not $3,000.
