  • Single-Ear Configuration Maintains Spatial Awareness And Environmental Safety
  • Universal Anatomical Design Eliminates Sizing Variables Across User Populations
  • Dual Connection Methods Support Neck Loop Lanyards Or Belt-Worn Receiver Placement
  • Hard Polymer Housing Enables Rapid Disinfection Between Patron Uses
  • Mono Jack Connectivity Provides Backward Compatibility With Existing Receiver Inventory

The Listen Technologies LA-404 addresses a critical challenge in assistive listening deployments: delivering intelligible program audio to users who must remain aware of their surroundings. Integrators installing ALS systems in houses of worship, performing arts centers, courtrooms, and lecture halls will find this single-ear solution meets ADA requirements while supporting patron safety and engagement with their environment.

Unlike dual-ear options that isolate users, this ear bud sits lightly in one ear to provide 82 dB output sensitivity without blocking external sound. The universal anatomical fit eliminates the need to stock multiple sizes, simplifying inventory for facility managers. Deployment flexibility is built in: connect directly to an integrated neck loop lanyard for discreet wear, or use the included extension cable with belt-clip receivers for patrons who prefer pocket carry.

Designed for institutional use, the hard polymer housing withstands repeated disinfection cycles with LA-901 wipes between users, and accepts disposable LA-163 foam cushions to reduce cross-contamination concerns. The mono 3.5mm termination ensures compatibility across Listen Technologies receiver platforms and legacy installed systems.
