The ListenWIFI Audio Receiver LWR-1050 offers advanced assistive listening capabilities, enabling venues to comply with disability and accessibility standards. It streams real-time audio from ListenWIFI Audio Servers via Wi-Fi directly to receivers, providing crystal-clear, low-latency audio. Venues can easily distribute these receivers to guests for an enhanced listening experience.

The LWR-1050 is highly automated, connecting automatically to the appropriate channel based on its location with the help of Listen Beacons. This ensures a seamless audio experience, especially useful in venues with multiple channels. For added convenience, the receivers can be used with wired headphones or an inductive neck loop for hearing aids with a T-Coil, simplifying the management of hearing assistance devices and reducing the complexity of supporting personal smartphones.

Ideal for various settings, such as classrooms, places of worship, and theaters, the LWR-1050 provides superior assistive listening.
