That’s okay. In the Synapse 3 app you can use the power saving mode so the headset will turn off after certain time when not in use. Feel free to check our self-help page for product updates and troubleshooting steps or PM me anytime should you need assistance. Thank you!

They’ll automatically turn off, when no sound is played after some time (time is adjusted in Power tab in Synapse).
