  • Unidirectional Noise-Canceling Electret Microphone Rejects Off-Axis Bleed For Clean Talkback
  • Dual Over-Ear Speaker Design Provides Passive Attenuation In High-SPL Production Environments
  • 250-Ohm Headphone Impedance Matches Professional Audio Systems And ListenTALK Platforms
  • CTIA-Compliant Connector Ensures Drop-In Compatibility With Assistive Listening Infrastructure
  • Extended Cable Reach Allows Crew Mobility During Live Production And Broadcast Operations

The Listen Technologies LA-454 headset addresses the challenge of maintaining intelligible two-way communication in high-SPL environments where ambient noise interferes with typical headset performance. Its dual over-ear design provides passive attenuation that allows engineers, stage managers, and production crew to hear clearly without increasing volume to unsafe levels. The integrated boom mic keeps hands free for equipment operation while maintaining consistent microphone positioning.

This headset is engineered for professional use in live sound, broadcast production, and industrial facilities where hearing protection and communication clarity are non-negotiable. The unidirectional noise-canceling microphone rejects off-axis sound, ensuring your voice reaches the other end of the intercom or talkback system without bleed from nearby sources. The 250-ohm headphone impedance is matched to professional audio systems, and the CTIA-compliant 3.5 mm connector integrates with ListenTALK systems and other assistive listening platforms used in tour production, corporate AV, and accessibility applications.
