Optimized for exceptional in-ear comfort, AirSoft’s new four-flange design creates a better seal in the ear canal, delivering optimal protection and increased comfort for long-term wear. Internal fins create an interlocking, noise-blocking barrier within the air pocket, providing dependable attenuation for all wearers upon proper insertion. At the same time, AirSoft’s firm stem and tapered shape facilitate easy insertion and removal, and allow the earplug to sit comfortably in the ear canal.
