Updated: 05-Feb-2026 | Answer ID: 837
This answer will show you how to resolve audio quality issues on the Razer Nari Series headset while using THX.

Effective February 3, 2026, Razer Synapse 3 will no longer receive updates or support cloud services. After this date, cloud syncing of configurations across PCs using the same Razer ID will be disabled.

Note: Your installed devices will continue to be configurable in Razer Synapse 3. However, if you uninstall these devices completely, you will need to upgrade to Razer Synapse 4 to continue customization.

Download Razer Synapse 4 and migrate your existing Razer Synapse 3 profiles using the Profile Migration Tool to retain access to your configurations. See How to migrate your Razer Synapse 3 Profile to Razer Synapse 4 for instructions.

Step-by-step process

  1. Plug in your Razer Nari Headset to your system via USB cable. 

  2. Expand the system tray by clicking the arrow found on the lower right side of your desktop. Right-click on the Razer Central icon and click “Check for Updates.”
