The invention discloses a near field communication (NFC) based brain wave sensing bluetooth earphone, which is characterized in that an earphone body comprises a brain wave sensor, a filtering and amplification unit, an analog-to-digital converter and a brain wave acquisition and processing chip which are sequentially connected, and the filtering and amplification unit comprises a first amplifier, a wave trap, a low-pass filter, a high-pass filter and a second amplifier, which are sequentially connected, of high-impedance differential input. The earphone body is a bluetooth earphone. The earphone body further comprises an NFC module, wherein the NFC module is connected with a bluetooth module through a bluetooth control circuit which is used for controlling the bluetooth module to realize automatic matching and communication, and the NFC module is further connected with a target terminal through an NFC transmitting and receiving antenna. The NFC based brain wave sensing bluetooth earphone enables users to carrying out a matching operation directly through NFC, the target terminal is controlled to carry out corresponding actions through brain waves, and the manipulation is convenient.
