Disclosed is an NFC-based Bluetooth earphone sensing an electroencephalographic α wave signal. An earphone body comprises a brainwave sensor, a filter and amplification unit, an analog-to-digital converter, and an brainwave collection and processing chip that are connected in sequence and distributed in a brain's occipital area. The filter and amplification unit comprises a first amplifier, a wave trap, a low-pass filter, a band-pass filter, and a second amplifier that are connected in sequence and have high-impedance differential inputs. A rear-mounted earphone body comprises a left ear hook, a rear mounting piece, and a right ear hook that are fixedly connected in sequence. The brainwave sensor is fixedly connected to the rear mounting piece through a connecting rod. An NFC module is connected to a Bluetooth module through a Bluetooth control circuit configured to control the Bluetooth module to implement automatic pairing and communication. The NFC module is further connected to a target terminal through an NFC transceiver antenna. The present invention enables a user to directly perform a matching operation by using NFC, controls a target terminal to perform a corresponding action by using a brainwave, and is convenient to manipulate.
