Phonak Eon Sphere

Phonak Audéo Eon Sphere is a rechargeable behind-the-ear hearing aid with the receiver in the ear canal (RIC). It is the third generation of Phonak's AI-supported Sphere series. Phonak states that it is 25 percent smaller, 20 percent lighter and uses 37 percent less energy than the previous Sphere generation.

Sound and hearing features

The device's HYPERSONIC AI chip, with Spheric Speech Clarity 3.0, uses a deep neural network to separate speech from surrounding sounds in crowded, noisy places. Phonak states a signal-to-noise ratio improvement of up to 10 dB in complex group conversations. AutoSense OS AI 8.0 continuously analyses the environment and adapts the settings automatically; WindBlock 2.0 works to reduce wind noise. The Sphere feature is available in the Eon family at Standard, Advanced and Premium technology levels. The device can be used for mild to profound hearing loss.

Connectivity and app

The device connects via Bluetooth to your phone, music and TV sound, and works with iPhone and Android phones. Phone calls can be made hands-free using the device's own microphones. With Auracast broadcast audio support, you can join Auracast broadcasts in places such as airports, meeting halls or places of worship. In the myPhonak app you can change the volume and programs, and get remote fine-tuning from your hearing care professional when needed. It also works with Roger microphones and receivers.

Charging and use

The device runs on a rechargeable battery, so there are no batteries to change. Phonak states up to 38 hours of use on a full charge; actual time varies with hearing loss, streaming use, environment and battery condition. Besides the desktop charger, there is also a portable charging case with its own battery. A fast charging option is available for a quick top-up.

Durability and colours

The device is specified as IP68 rated against dust and water. There are eight colour options: Graphite Gray, Silver Grey, Velvet Black, Champagne, Chestnut, Sandalwood, Sand Beige and Sienna Red.

Who is it for?

Phonak Audéo Eon Sphere can be used for mild to profound hearing loss. Suitability depends on the degree of your hearing loss and the shape of your ear; the decision is made together after an audiological assessment.

At our centre in Pendik we first carry out a free hearing test, then, if the device is suitable, you can try it in your daily life. You can find other rechargeable models on the rechargeable hearing aids page.
