Please follow the illustrated instructions below:
- Do not plug the dongle into the controller or into the back of the PS4/5.

- Use the physical buttons on the Quest to adjust the volume and increase it.
- If you have both Bluetooth and the Dongle connected to the Quest, it may cause low volume. In this case, go to the Bluetooth settings on the Quest, forget the Bluetooth audio device, and restart the Quest to resolve the issue.
If the volume is low, please try the following steps to resolve the issue:
- It's possible that your phone is in silent mode and received a notification that interfered with the audio from the dongle. Please try disabling silent mode on your phone.
- In your Quest, you need to use the physical buttons to increase the volume on the dongle side. Please try using the physical buttons on your Quest to increase the volume.
If you experience poor sound quality, it may be due to the following reasons:
- When call audio is mixed with game audio, the volume of game audio is reduced. This is done to help you have better call quality.
- Currently, mixing two audio sources together can have some impact on sound quality. We are working to address this issue and optimize it through future firmware updates.
We apologize for any inconvenience caused. Please try the above methods to see if there is any improvement. If you have any further questions or concerns regarding the product, please feel free to contact me.

We have conducted extensive testing to ensure excellent latency performance with our product. To ensure optimal performance, please check if your VR device is currently connected to a Bluetooth audio device, including the Vega T1. If it is, we recommend disconnecting from any Bluetooth audio connections to minimize latency.For the lowest latency experience, please use the Vega T1 dongle to connect your VR/PC/Console, rather than relying on a Bluetooth connection. We have observed that using both the Vega T1 dongle and a Bluetooth connection simultaneously can introduce latency issues. Please note that simultaneous connections to your VR/PC/Console may result in delays or other latency-related problems.If you have both Bluetooth and the dongle connected to your VR/PC/Console, we recommend following these steps to resolve the issue:
- Go to the Bluetooth settings on your VR/PC/Console.
- Forget the Bluetooth audio device that is currently connected.
- Restart your VR/PC/Console.
Please note that it is important to insert the Dongle into the front of the main unit and avoid plugging it into the back. Additionally, ensure that there are no obstructions around the Dongle for optimal performance.If you are experiencing high latency only in Beat Saber, please refer to the following method to resolve it.First, make sure you have upgraded to the latest firmware. Follow the steps below:
- Power on the Dongle(connected to the HMD or PC) and connect it to your earbuds.
- If the app displays "Update Available," click "Update Firmware" to view the update information.
- Ensure that the earbuds are placed in the charging case, and the charging case remains open until the firmware update is complete.
- During the upgrade process, keep the Dongle powered on (connected to the HMD or PC) and within 20 inches of the earbuds.
- The Dongle will restart after the update is complete.
Next, if you are still experiencing latency, please attempt the following settings:Options -> Settings -> Audio tab, make sure that the Override Audio Latency setting is turned on; start from around 30ms,and try to tune.
