Emotiv EPOC

Overview
The Emotiv EPOC is a 14-channel wireless EEG system (proprietary wireless interface) using saline electrodes. This device uses a low-power Nordic Semiconductor's chipset - it does not use Bluetooth. However, later EEG models released by Emotiv do use BT4.0, specifically, the Emotiv Insight and the Emotiv EPOC+.
