With Listen’s unique DSP SQTM noise reduction technology, users experience 20 dB less noise and hiss than any other listening device. Advanced green battery technology dramatically reduces costs of ownership and hassles while reducing the number of batteries in landfills. A field replaceable Lithium-ion battery is included with the unit. The integrated neck loop / lanyard with DSP loop driver, improves the listening experience for T-coil users. iDSP is the smallest device of its kind, making it easier to wear and easier for venues to dispense, store and maintain.
The LR-5200-072 has an OLED display to program channel names, monitor battery status, channel status, and charge activation. Programmable channel select button allows user to cycle through active channels, seek to or lock to a channel. Connect the iDSP neck loop/lanyard or ear phones via two 3.5 mm output jacks (ear phones could be shared). The Micro USB connection is used with included iDSP software for charging, set up, programming, inventory management and firmware updates.
The result is an exceptional listening experience in places where it’s difficult to hear, like: theaters, lecture halls, concert venues, houses of worship, and more.

This makes it simple to operate for end users that need to select between multiple active channels. The Listen Button can also be used to search for an active channel and lock the receiver on a specific channel.
