Outstanding audio clarity and quality

Listen Technologies LR-3200-072 basic DSP RF receiver (72 m㎐) has outstanding audio clarity and quality with the best range and reception in its class. Part of Listen's Intelligent Digital Signal Processing (iDSP) line, the LR-3200-072 is the smallest device of its kind, resulting in a compact unit that won’t burden the end user. An integrated neck loop/lanyard (sold separately) makes each receiver easy to wear, and the DSP loop driver offers an improved listening experience for anyone with a T-coil-equipped hearing aid. Dual 3.5㎜ output jacks also allow receivers to be shared between users. Each receiver is equipped with a micro USB connection which can be used with free iDSP software for charging, set up, programming, inventory management and firmware updates. Extended speaking sessions, presentations and more can be challenging for other devices, but the LR-3200-072 incorporates advanced Lithium-ion rechargeable batteries that offer long life and reliable power.


  • RF receiver offering best-in-class sensitivity and sound
  • Integrated neck loop/lanyard with DSP loop driver for an enhanced T-coil listening experience
  • Smallest device of its kind makes it easier to wear and use and for venues to dispense, store and maintain
  • Limited lifetime warranty with hassle-free support
  • Advanced rechargeable battery technology eliminates the costs and hassles associated with frequent battery replacement
