How Does Audio TimeSync Work?

Most smart wall clocks rely on WiFi or Bluetooth to sync time. That means configuring routers, pairing devices, installing apps — and hoping the connection stays stable. OVOSONO takes a fundamentally different approach.

With Audio TimeSync, the OVOSONO Circle 350 receives the exact time through an ultrasonic audio signal. No network, no pairing, no app. Just hold your phone near the clock — done.

How Audio TimeSync Works

The synchronization process takes just a few seconds and works with any device that has a speaker:

• Open ovosono.com/timesync on any device with a speaker
• Hold the device near the OVOSONO Circle 350 (within about 30 cm)
• The clock receives the encoded time signal and sets itself — done in seconds

The technical elegance lies in the detail: time data is transmitted on ultrasonic frequencies above the range of human hearing. You hear nothing — the clock understands everything. And it works with any smartphone, tablet, or laptop.

Advantages Over WiFi and Bluetooth

Audio TimeSync eliminates the typical weaknesses of wireless connections. A direct comparison shows the differences:

Conclusion

Audio TimeSync is the simplest, most private way to sync a wall clock. No accounts, no passwords, no network — just sound. A technology that does exactly what it should, and nothing more.
