Tinnitus Relief That Fits Into Everyday Life.
Sonovo Unison™ combines hearing support and tinnitus relief in one discreet, open-ear design. Using gentle bone conduction, it delivers clear, balanced sound without blocking your ears, helping you stay aware, confident, and comfortable throughout the day.
Whether you’re working, relaxing, or socialising, Unison fits seamlessly into your routine, bringing relief that looks and feels natural.
How Unison Works.
Unison uses bone conduction technology to deliver sound through gentle vibrations along your cheekbones, bypassing the eardrum entirely.
This open-ear design helps reduce tinnitus contrast by keeping your ears active and aware of external sound, without masking the world around you.
Microphones discreetly built into the frame amplify voices and soften background noise, helping conversations feel clearer and more natural.
Over time, this continuous, comfortable sound stimulation can support habituation, your brain’s natural process of tuning out tinnitus.
FAQs
Please read our FAQs page to find out more.
Is Unison a cure for tinnitus?
No, Unison isn’t a cure for tinnitus, but it can help reduce how noticeable your tinnitus sounds feel.
By delivering gentle sound through bone conduction, Unison helps your brain focus on external sound instead of internal noise, supporting the natural process of habituation.
How does bone conduction help with tinnitus?
Bone conduction sends sound vibrations directly through your cheekbones to your inner ear, bypassing the eardrum.
This helps keep your hearing system active and reduces the contrast between tinnitus and silence, a key factor in long-term relief.
Can I still hear my surroundings while wearing Unison?
Yes! Unison’s open-ear design keeps your ears free, so you can hear the world around you naturally while still experiencing relief.
You’ll stay aware of conversations, traffic, and background sounds.
Can I use Unison with prescription lenses?
Absolutely. Unison frames are prescription-ready, and your optician can fit your lenses into the frame just like any regular pair of glasses.
How is Unison different from traditional hearing aids or maskers?
Unlike traditional hearing aids or white-noise maskers, Unison doesn’t amplify everything or block sound.
Instead, it uses precise bone conduction to deliver clear, natural sound, reducing tinnitus perception while keeping external hearing open.
How long does it take to notice results?
Many people feel more relaxed within the first few days of regular use, while others may notice gradual improvement over several weeks.
Tinnitus habituation takes time, but consistency is key.
