Open-Ear Air Conduction Bluetooth 5.4 Headphones

Upgrade your active audio experience with the Sony Ericsson Gd31 / Gd36 Open-Ear Air Conduction Wireless Bluetooth Headphones. Featuring an open-ear hanging hook design, these non-in-ear sports headphones utilize directional air conduction technology to deliver 360-degree panoramic stereo sound directly into the ear canal without plugging it. This design prevents ear fatigue while keeping you aware of surrounding traffic, outdoor sound environments, and office conversations during running, workouts, and daily commutes.

Constructed from lightweight, skin-friendly PC+ABS plastic materials, the Gd series ear-hook architecture wraps securely around the outer ear to prevent slipping during intense physical movement.
