Manufacturer (Listen Technologies, maker of the neckloop and of the RF, infrared, Wi-Fi and two-way receivers it is sold for)

Summary

Listen Technologies' page and specifications for its passive neckloop, which Pro Audito's 2026 bench test ranked second of six.

Key findings

  • Gives a frequency response of 20 Hz to 15 kHz (±3 dB re 1 kHz), an impedance of 3 to 6 ohms at 1 kHz, a maximum power input of 1 W, and an input sensitivity of "380 mVrms @ 1 kHz produces 400 mA/m".
  • Lists IEC 62489-1:2010, CE and UKCA under standards, and claims an "Industry leading magnetic field strength range".
  • Says the neckloop works with any telecoil-equipped hearing aid or cochlear implant and with any of the maker's receivers, and lists its RF (72 and 216 MHz), infrared, Wi-Fi and ListenTALK receivers as the devices needed with it; it has a safety breakaway connection and a compatibility switch.

Limits

A maker's specifications without a stated measurement position or method, so they cannot be compared directly with the dummy-head measurements in Pro Audito's test. The date is the page's publication date in its metadata; it was last modified on 10 April 2025, and the page says specifications may change without notice.
