EmotivBCI is compatible with EMOTIV EPOC, EPOC+, EPOC X,  INSIGHT, and EPOC Flex (partial, see [Connecting EPOC Flex](/emotivbci/setting-up-your-eeg-device/connecting-your-headset/connecting-epoc-flex.md) for more detailed) headsets. Before you connect your headset to EmotivBCI, make sure your device’s battery is charged.

##

### Headset connection types priority

if your headset pairs with more than 1 connection type at the same time,  connection types priority will follow 2 cases below:

* **Case 1**: In case of no prior connections, the priority for different types is as follows:\
  USB cable connection -> USB dongle connection -> BTLE connection<br>
* **Case 2:** In the case of prior connections, a new incoming connection will be queued for about 30s until the first connection can disconnect&#x20;

**Also in this section:**
