High latency in VR Quest, Pico, PC, Console.

PrismXR has conducted extensive testing to ensure excellent latency performance with its 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, PrismXR recommends 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. Using both the Vega T1 dongle and a Bluetooth connection simultaneously can introduce latency issues. 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, PrismXR recommends the following steps to resolve the issue:

1. Go to the Bluetooth settings on your VR/PC/Console.
2. Forget the Bluetooth audio device that is currently connected.
3. 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.

Can I use PrismXR Vega T1 when using a PC and VR headset (PCVR) via a Link Cable?

Yes, PrismXR Vega T1 can be used in PCVR by using a Link Cable. Follow these two simple steps:

1. Do not plug the Link Cable to the Dongle's USB-C port directly, as it does not support data transfer. Please plug the dongle into the USB-C or USB-A port (by using the included USB-A to USB-C adapter) on your PC instead of your VR headset.
2. Connect the Link Cable from another USB-C or USB-A port on your PC to your VR headset and choose the audio output as PrismXR Vega T1.

3. Open the charging case and keep it open with the earbuds inside. Press and hold the SET button on the case for 3 seconds until the LED indicator flashes blue to let the earbuds enter pairing mode.
4. When both the Dongle and Charging case lights up in blue, it indicates that you have successfully completed the Dongle reset.

How to switch the dongle connection to multiple consoles?

After you've successfully paired the extra dongle, you can now switch the dongle connection among multiple consoles:

1. When the dongle lights up in blue, it means the earbuds are connected to this dongle.
2. You can switch the dongle connection on the app. You can also rename the dongle on the app as well.
3. When the app shows the dongle connection has switched successfully, the other dongle in the different device will light up in Blue after the flashing blue light.

What should I do if the mic picks up no sound while making calls on PrismXR Vega T1?

Please try the following methods to resolve this issue:

2. Please check if the Dongle has completed a firmware upgrade. Here's the process for upgrading the Dongle:
   1. Power on the Dongle (connected to the HMD or PC) and connect it to your earbuds.
   2. If the app displays "Update Available," click "Update Firmware" to view the update information.
   3. Ensure that the earbuds are placed in the charging case, and the charging case remains open until the firmware update is complete.
   4. During the upgrade process, keep the Dongle powered on (connected to the HMD or PC) and within 20 inches of the earbuds.
   5. The Dongle will restart after the update is complete.
3. Please try plugging the dongle into the computer or using it in a different environment to help determine if there is an issue with environmental interference. Factors such as metal or wireless interference, like a Wi-Fi extender, can affect its performance.
   1. Move your wireless interference further away and then try again.
   2. Use a USB-C to USB-C/USB-A data cable to connect your PS5 and the dongle. This way, you can keep the dongle a bit further away from wireless interference.
