# About losing connections

If your headset loses connection with Builder, it could be due to a loss of Bluetooth connection, a loss of battery power, or a loss of contact quality.

When a connection is lost, Builder automatically does the following:<br>

1. Pauses the experiment.&#x20;
2. Prompts the participant to either reconnect their headset or abort the experiment.&#x20;
3. If the participant decides to abort the experiment, the experiment's data is saved and the participant is taken back to the Builder homepage.&#x20;
4. If the participant reconnects their headset and decides to continue the experiment, the experiment will start again at the beginning of the most recently completed phase. The new data recorded from this point will have a 'continue running' marker so that the disconnection can be seen when the data is analyzed.
