1. Audio Delays (Lag)
The C81 is aptX Low Latency certified, reducing lag to less than 40ms, which is virtually unnoticeable. Ensure your paired headphones also support aptX Low Latency for the best experience.
2. Poor Sound Quality in Talk Mode (PS5)
When chatting in-game, the dongle may switch to a mono, 16kHz bit rate signal due to Bluetooth technology limitations. To improve chat quality, use the included mini mic plugged into your controller and ensure your PS5's microphone input is set to "Controller Headset".

3. Connection Issues / Re-pairing
- Ensure both the C81 and your Bluetooth headphones are in pairing mode.
- Keep the devices within close proximity during pairing.
- If connection is lost, try unplugging and re-plugging the C81, then re-enter pairing mode on both devices.
- Physical obstructions can affect Bluetooth range. Try to minimize barriers between the C81 and your headphones.
