SONNET 3 is our behind-the-ear audio processor. With the slogan “Be Flexible. Be Free,” SONNET 3 has been designed with the flexibility to fit your hearing and lifestyle needs, giving you more freedom.

SONNET 3 is available as both a cochlear implant audio processor and an electric acoustic stimulation (EAS) audio processor. Any MED-EL recipient with a SYNCHRONY series, CONCERTO series, SONATA series, PULSAR, C40+, or C40 implant can use SONNET 3.

SONNET 3 is equipped with FineHearing to provide the closest to natural hearing possible. FineHearing technology offers better hearing and a richer, fuller hearing experience.

In addition, SONNET 3 has Automatic Sound Management 3.0 with Adaptive Intelligence. This automatically changes the volume and other settings to match the hearing environment you are in. It also reduces background noise so you can hear more clearly in busy environments.

SONNET 3 uses dual microphones and the latest technology to give you microphone directionality. With two microphones, SONNET 3 can focus in on the sounds in front of you and reduce background noise. This makes it easier to hear the most important sounds around you, especially in noisy environments.

You can also use the universal connectivity device AudioLink XT as a remote microphone for SONNET 3. Put it on the table and hear the conversation more clearly at dinner, in meetings, or in many other situations. Or use AudioLink XT to connect to non-smart TVs.

SONNET 3 measures 52 mm high, 39 mm deep, and 9.5 mm wide with the Rechargeable Battery Standard. Including the battery pack and two zinc-air batteries, SONNET 3 weighs only 9.5 grams. With the Rechargeable Battery Micro, SONNET 3 weighs just 7 grams and is only 46.86 mm high.

SONNET 3 is also sweat resistant so you can enjoy uninterrupted hearing during high-energy activities.

Both RONDO 3 and SONNET 3 offer our latest sound coding technology, Automatic Sound Management 3.0. They also both have two microphones, offering a similar level of hearing performance. But when it comes to design, they have some distinct differences. RONDO 3 sits off the ear, whereas SONNET 3 hooks behind the ear. RONDO 3 is charged wirelessly and has an all-in-one design for extra simplicity. SONNET 3’s modular design makes it compatible with different wearing options like SONNET 3 BabyWear. SONNET 3 is equipped with integrated direct streaming. To stream with RONDO 3, you need the AudioStream Adapter.
