The SPM Vibration EAR12 is a headphone set equipped with two earphones and a collapsible headband, allowing for convenient storage when not in use with ear defenders. The headset is tested and approved according to the PPE directive 89/686/EEC and the EMC directive 89/336/EEC, ensuring compliance with CE labeling standards.

The EAR12 headphones are compatible with the SPM Bearing Checker, ELS14, and Leonova Emerald/Diamond devices.

The headband features individually sprung wires made of stainless sprung steel, ensuring even pressure distribution around the ears. These steel wires maintain their resilience better than plastic across a wide temperature range. The design includes low, two-point fasteners and easy height adjustment without any protruding parts.

Soft, wide foam and fluid-filled sealing rings with built-in pressure-evening channels provide low pressure, effective sealing, and optimal comfort. The connection cord, made of soft spiral polyurethane, extends from 0.75 to 1.4 meters and is equipped with a 3.5mm stereo plug.
