Summary
Listen Technologies' online manual for ListenWIFI, which streams venue audio over the Wi-Fi network to an app on listeners' phones and to the maker's own Wi-Fi receivers.
Key findings
- States that each server supports up to 500 listening devices, phones and receivers together, on 2 to 16 channels depending on the model, and that servers stacked on one network can reach 512 channels and 16,000 users.
- Recommends involving the venue's IT staff, because network and firewall settings may block the traffic. If the network blocks multicast DNS, servers have to be added by IP address. Audio packets carry a quality-of-service tag, and the manual suggests some experimentation with the tag and with voice or video priority to get lower latency and fewer dropouts.
- Describes the ways to join: choosing the venue network in the phone's settings or scanning a Wi-Fi QR code, then picking a channel in the app, scanning a channel QR code, or being switched automatically by Bluetooth beacons placed in each room. It presents beacons as a way to keep listeners on their own room's channel without passwords.
- System Set-Up, step 9 (Functional Testing), asks installers to check network and server connections, channel access, audio quality and latency using both a smartphone and a dedicated receiver, including automatic selection on entering beacon zones. The beacon Installation section asks for coverage of the intended room and a stronger signal there than from other beacons, to avoid selecting another room's channel.
- Recommends wired headphones, or a neckloop for hearing aids with a telecoil, and says Bluetooth devices are "not recommended" because of the significant latency they can add.
- Says dedicated Wi-Fi receivers are "often required" for venues that must meet laws mandating that receivers be available, listing "(ADA/CBC/IBC/DDA/etc.)". The receivers take wired headphones or a neckloop and typically charge in 2 to 3 hours.
- States that the app is free "without any advertisements", and that keeping servers and other components updated is essential for compatibility with current smartphones and operating systems.
- Mobile App, Operational Instructions, step 1 states that the mobile app is free to download with no recurring payments required. This statement prices the app alone; it does not price the venue's server, network, receivers or support.
Limits
A maker's manual: the capacity figures are its own, with no test conditions or network described, and it gives no latency figures and no receiver battery life. The online manual changes over time; the date is the 'updated' date shown on the page, and its metadata gives first publication on 14 May 2025. It links an accessibility calculator for receiver numbers under US, Californian and Australian rules.
