The MX3-4, our four-input wireless assistive listening system, is an excellent option for restaurants, sports bars, and additional spaces where multiple audio sources are needed. Thanks to seamless integration with each user's smartphone or mobile device, the costs associated with installing and operating a streaming audio system are much lower, and the listening experience is ideal for everyone. Additionally, the MX3-4 uses a minimal amount of bandwidth from your existing wireless internet service, meaning there is virtually no effect on speed or signal strength. The Audio Everywhere from Listen Technologies cloud server interface makes updates and other service options simple and fast.
