  • Industry Leading Magnetic Field Strength Ensures Reliable Signal Transfer To Telecoil Devices
  • Safety Breakaway Connection Prevents Entanglement During Active Use
  • Compatibility Switch Optimizes Performance Across Diverse Hearing Aid Models
  • 3.5mm Stereo Connector Provides Universal Interface With Listen Technologies Receivers
  • Lightweight Construction Enables Extended Wear Without User Fatigue

The Listen Technologies Advanced Neck Loop is engineered for AV integrators installing assistive listening systems in houses of worship, performing arts venues, conference centers, and educational facilities where telecoil compatibility is required. The device interfaces with any Listen Technologies receiver via 3.5mm stereo connection and generates industry-leading magnetic field strength to ensure reliable induction coupling with t-coil-equipped hearing aids and cochlear implants.

A built-in compatibility switch allows installers to optimize performance across diverse hearing device models, while the safety breakaway connection prevents entanglement hazards during active use. The lightweight design enables extended wear without fatigue, making it suitable for multi-hour events and permanent installation kits where user comfort directly impacts adoption rates.

System designers benefit from proven interoperability with the full Listen Technologies receiver lineup, streamlining procurement and reducing training overhead. Compliance with IEC 62489-1:2010 standards ensures predictable performance in regulated environments, while wide operating temperature and humidity tolerances support installation in climate-variable spaces.
