About the "auto power off" setting

If no sound comes through the headphones for a specified amount of time, the headphones are automatically turned off. Users can choose from "Always on," "5 minutes," "10 minutes," "30 minutes," and "60 minutes."

How to wake up the headphones from the “auto power off” mode

Hold down both the left and right touch sensors until the LED light turns on (approx. 2 seconds). If the headphones do not turn on, please ensure they are fully charged.

How to update your RZ-S500W or RZ-S300W?

Keeping up with the latest updates on your RZ-S500 or RZ-S300 is easy
Thanks to Panasonic Audio Connect App, not only you can customize your setting, connect the Panasonic True Wireless earbuds or find the earbuds location, but also the App will notify you about new firmware availability.

Before you start

Charge both the left and right sides of the headphones to more than 70%.
The update process will take approximately 15 minutes* to complete.
The file size is about 1.8 MB.

*The update may take up to an hour depending on the device and internet environment.

Checking the firmware version and updating

You can use the free “Technics Audio Connect” app* to update the firmware of the connected headphones.

*Compatible with smartphones and tablets that are equipped with Android™ 6.0 or higher and that support Google Play™, or an iPhone ®, iPad ® and iPod Touch ® equipped with iOS9.3 or higher.
*Images below are of the app on an Android™ device. The user interface will differ slightly on iOS, but the procedure is the same.

When the latest version of the firmware is detected, tap “Update”.

How to update your RZ-S500W or RZ-S300W?

When you tap "Update", the firmware is transferred to the headphones and the update will begin. Transfers may be interrupted or slowed down if music is being played or there is a call during the transfer. Start the transfer with the headphones outside of their charging cradle, set them down close by and do not operate them.

How to update your RZ-S500W or RZ-S300W?

Wait until the update completes, without operating the headphones or the app.
After the firmware has been updated, the headphones will automatically restart and reconnect with the handset.
The app will not work properly until the update is complete. Do not try to operate the headphones or the app while the update is in progress.

The update is complete when the main screen appears.
