It is a Electric neck massager.

Scientific name: N/A — manufactured object.

A gray, U-shaped wearable electronic device designed to fit around the human neck. It has two curved side arms extending forward, each with smooth, rounded plastic housings and darker rubberized or padded inner surfaces. Near the inner curve are oval contact pads or massage heads positioned to press against the sides or back of the neck. The rear portion forms a thicker curved bridge, and there appear to be small hinge or joint sections with metallic-looking bands where the arms connect. The object is compact, symmetrical, and made primarily of molded plastic with soft contact surfaces..

Many modern electric neck massagers use either vibration, heat, kneading rollers, or low-level electrical muscle stimulation to relax neck muscles, but they should be used cautiously by people with pacemakers or certain medical conditions..

The object has the characteristic collar-like U shape of a wearable cervical massager. The paired inner pads resemble massage or electrical stimulation contact pads intended to touch the neck, while the two forward arms look like handles or control housings often found on cordless neck massagers. Its molded plastic construction, rounded ergonomic shape, and small button-like feature support identification as an electronic consumer device rather than a biological or geological specimen.
