The EKSAtelecom S30 Air Conduction Headset is open-style telecom earbuds. This system utilizes a distinctive acoustic design and specific unit speakers to emit sound in a targeted direction. Clarity is optimized within this specific area, while remaining generally imperceptible in other directions.

The adjustable earhook design gives a comfortable and ideal fitting for every ear type at any angle possible.
