Devia OWS Lite4 Open-Ear Wireless Earphones (EM426) - Black

Description

The Devia OWS Lite4 wireless earphones (manufacturer reference EM426) in a black finish redefine portable audio ergonomics thanks to Open Wearable Stereo (OWS) technology. Specifically configured for office staff, field technicians, athletes, and B2B resale, these earphones rest on the ear contour without obstructing the ear canal. This innovative architecture eliminates any pressure or ear heating, while allowing the user to remain perfectly aware of environmental sounds.

In terms of acoustic engineering, the fourth-generation Lite4 integrates a Bluetooth 5.3 controller that ensures highly stable audio transmission, imperceptible latency, and perfectly regulated energy consumption. To compensate for the open structure, the onboard digital signal processor (DSP) orchestrates a highly directional air conduction flow. Sound is projected in a targeted manner towards the eardrum, maximising the amplitude of low frequencies and the clarity of voices while minimising sound dispersion to the outside.

The design of the EM426 relies on flexible, ergonomic ear hooks, injected into a soft, memory-shape polymer that guarantees absolute mechanical stability, even during dynamic movements or prolonged use at the workbench. The compact storage and charging case integrates a battery optimised to offer multiple recharge cycles, extending overall battery life to cover long work or travel sessions. The matte black finish provides a sober and professional aesthetic, highly resistant to micro-scratches.

Workshop Advice & Usage

The Open-Ear format of the Devia OWS Lite4 is the ideal solution for clients or colleagues who cannot tolerate the rubber tips of classic in-ear headphones (irritations, blocked ear sensation). During deployment or resale, explain clearly that this type of earphone is designed not to isolate from the environment, which constitutes a major safety feature for technicians who need to hear alert signals or machines in the workshop. Maintenance note: The matte black colour is extremely robust, but the accumulation of skin sebum and workshop micro-dust on the flexible hooks can eventually alter the charging contacts in the case. Advise a quick weekly cleaning of the contact areas using a dry microfibre cloth to maintain a perfect connection with the dock's copper pins.
