Switch between sound amplification and Bluetooth audio, without changing device.
Two ways to habituate, one wearable device.
Sound amplifier mode.
Enhance ambient sound around you in a more open and natural way. This mode is designed for people who want greater awareness of the sound environment around them, while also using external sound as part of a daily sound enrichment routine.
Bluetooth audio mode.
Connect your phone and play the audio that works best for you. Whether that is soundscapes, podcasts, music, white noise, nature sounds, or other audio from your preferred apps, Sonovo Z28 gives you more control over how you listen.
Why bone conduction feels different.
Unlike traditional in-ear audio devices, Sonovo Z28 uses bone conduction to deliver sound while keeping the listening experience open-ear. That means you do not need to rely on earbuds sitting inside the ear canal.
For many people, this creates a more comfortable and less intrusive way to listen throughout the day. It also makes the device feel more wearable for those who prefer a lighter, more open style of audio.
Because nothing sits in the ear canal, many people find it comfortable to wear alongside other things, or for longer than in-ear devices.
Lightweight, discreet, and easy to fit into everyday life.
Designed for every part of the day.
Sonovo Z28 is designed for people who want more flexibility from the way they listen. Whether you are at home, at work, on the move, or winding down in the evening, Z28 gives you an open-ear way to introduce sound into your day through amplifier mode or Bluetooth audio.
For home.
Use sound enrichment to make quieter environments feel less stark, while keeping your listening experience open and comfortable.
For work.
A discreet, open-ear option for people who want greater listening flexibility during the day without relying on in-ear earbuds.
For active moments.
Lightweight, wearable, and built for movement, with an open-ear design that feels more natural throughout the day.
For night time.
Use Bluetooth mode to play the sounds or audio that suit your evening routine when you want a calmer, more flexible way to listen.
