Negative latency means that your audio comes before your visuals.

Update : We now measure negative latency values in test bench 1.5 and have extended our scoring curve accordingly. As a result, we have updated our review, and the scoring of this box has changed. Once paired to both devices, you can hear audio from both devices simultaneously. Next, you press the headphones' 'Bluetooth' button to pair them with a phone. You must first press the 'Pair' button on the Xbox console and then press and hold the headphones' power button for six seconds this pairs the headphones to the console. Update : We've changed Multi-Device Pairing from 'No' to 'Bluetooth + Console/Non-BT Wireless' as these headphones can connect to an Xbox console and a Bluetooth device at the same time. We've updated the Xbox One compatibility value of the 9X to reflect support for both mic and audio. We've tested for audio stuttering and sporadic disconnecting when the headphones are used via non-Bluetooth wireless. Retested Bluetooth for negative latency values and updated 'Noise Handling' test results. We've added a comparison between these headphones and the SteelSeries Arctis Nova 7X Wireless in Wired. However, the scoring of these tests hasn't changed. We've added information regarding user reports of poor muffled sound in the Sound Profile and Non-Bluetooth Wireless tests. The scoring of this test has changed from 8.0 to 6.0. We've re-evaluated Build Quality based on user reports about the hinges cracking and breaking from regular use.
