ReSound's flagship hearing technology
ReSound Sensia 9AI hearing aids for the conversations you want to be part of.
The dinner table. A busy café. The people who matter. Sensia 9 helps bring speech into focus while keeping you connected to the sounds around you.
Choose the compact rechargeable microRIE for Sensia's most complete automatic listening support, with Bluetooth streaming and care from a hearing professional.
Sensia 9 rechargeable is worth considering when your day moves between quiet moments and lively places—and you want hearing aids that adapt as you go.
Restaurants and family gatherings. Support for speech when background sound competes for your attention.
Changing surroundings. Automatic adjustments as you move from one listening situation to another.
Calls, music and podcasts. Direct audio from compatible devices, with controls on your phone.
Stay connected to the conversation in front of you and the world around you.
Mostly quiet, one-to-one listening? A lower Sensia level may be enough. A hearing professional can help match the technology to your hearing test, daily routine and budget.
Listen for yourself
Less competing noise. More of the conversation.
Press play, then toggle Intelligent Focus off and on as the conversation continues. Listen for the change in background noise without restarting the scene.
0:00 / 0:15
Start at a comfortable volume. Headphones can make the comparison easier to hear.
Manufacturer demonstration, not a prediction of your personal result. What you hear will depend on your hearing, fitting and surroundings. Intelligent Focus is available on Sensia 9 and 7 rechargeable microRIE models.
What to listen for
The recordings compare a voice in background noise with Intelligent Focus off and on. The change illustrates how competing sounds can be reduced to help you attend to the person speaking. You do not need to hear every word to explore the comparison.
Helpful technology, explained simply
Your surroundings change. Sensia responds.
In the rechargeable Sensia 9, Intelligent All-Around brings together sound sensing, directional microphones and AI noise reduction. The aim is practical: help you follow speech without shutting out your surroundings.
Intelligent All-Around
Keep up as the conversation moves.
At a gathering, the next speaker isn't always directly in front of you. Sensia 9 rechargeable balances awareness of the sounds around you with support for speech.
Why choose level 9?
Intelligent All-Around is exclusive to Sensia 9 rechargeable microRIE. It is the clearest reason to consider the flagship level if you want the fullest automatic support in the Sensia family.
Intelligent Focus
Give the person in front of you more attention.
Across a fitted pair, four microphones work together to focus forward. Intelligent Focus combines that directionality with AI noise reduction to make competing background sound less intrusive.
An everyday way to use it
Face the person you want to hear. Your hearing professional can help you make the most of the available listening programs and app controls.
AcoustIQ sound sensing
From a quiet room to a lively street.
AcoustIQ continually detects the listening environment and engages the appropriate sound-processing features as the situation changes.
Control when you want it
Let the automatic features help throughout the day, and use the ReSound Smart 3D app when you want to adjust the volume or fine-tune your sound.
Watch: How hearing aids make sense of sound · 3:36 · ReSound explainerRead the key idea
Hearing aids analyze incoming sound to distinguish listening environments such as speech, noise and music. This helps them choose how to process sound as your surroundings change. ReSound explains how its approach supports awareness of your surroundings as well as speech.
Choose the routine that suits you
Recharge each night, or change batteries as you go.
Sensia 9 comes in three receiver-in-ear styles. The rechargeable microRIE has the most complete AI feature set; the replaceable-battery models offer a different balance of power and features.
