  • Phonak Audéo EON R — Sienna Red
1 1

The Phonak Audéo CROS EON is for people with hearing in only one ear. Worn on the side that can't be aided, it picks up speech and sound from that side and streams it instantly to a Phonak Audéo EON R hearing aid in your better ear — so conversations, restaurants, and car rides stop depending on where you sit. It runs on Phonak's newest EON platform, matches the EON R in size and colors, and recharges in the same case. Pair it with an Audéo EON E90-R, E70-R, E50-R, or E30-R, and our licensed hearing care providers will program both sides to your audiogram before they ship.

Platform Comparison

The biggest Phonak upgrade in years

EON is Phonak's newest platform. Every model runs the new ERA chip, AutoSense OS AI 8.0, and WindBlock 2.0 — and EON Sphere adds the HYPERSONIC AI chip with Spheric Speech Clarity 3.0. Here's exactly what changed from the last generation.

Highlights of what's new:

  • 25% smaller and 20% lighter — the smallest Sphere Phonak has ever made
  • WindBlock 2.0 — 95% of wearers said it took the effort out of listening outdoors
  • Auracast™ broadcast audio — tune into airports, theaters, and TVs that broadcast sound
  • Up to 38 hours of battery life on a single charge

Why it matters day to day

Smaller than ever

25% smaller and 20% lighter than the last generation. Made to wear all day — most people forget they're wearing it.

Hear in wind

WindBlock 2.0 takes the effort out of listening outdoors — on walks, patios, and the back nine.

Auracast™ is here

The first Phonak with Auracast broadcast audio. Experience the front row wherever sound is broadcast.

All-day battery

Up to 38 hours per charge, with a pocket-size charger that tops you up on the go.
