Express 5

AudioFetch Express 5 is a compact and cost-effective solution that uses WiFi to transmit high-quality, low-latency audio from one or two televisions, set-top boxes, or other audio sources to personal mobile devices like smartphones and tablets. Works with most smartphone-connected hearing aids.

Integrated WiFi can operate in 2.4GHz or 5GHz band and be configured as an Access Point, or can be connected hard-wired or wirelessly into a pre-existing WiFi network, making it a simple installation for fitness clubs, sports bars, movie theaters, waiting rooms, meetings, conventions or wherever users need convenient, wireless access to in-house audio sources.


FetchExpress is an extremely flexible platform suitable for many applications.

Do members at your church need assistive listening or translation audio? Are you a tour guide leading guests through a quiet museum or loud outdoor location? How about a fitness instructor holding classes in a park? Or maybe you’re hosting an outdoor movie night and don’t want to disturb the neighbors? If you want your audience to hear better without distractions (or distracting others), FetchExpress is what you need.

“My senior-age members love the ease-of-use. The AudioFetch App functions well and is easy to use across all the devices we’ve encountered. I really like that the product is easy to install and maintenance-free. The one time I had a question, the support was very good.”


“We used the tour pack [FetchExpress for Tour Guide application] and it made a world of difference on the training session. Thank you!!”

This is based on minimal delays in the network/WiFi and thus represents sum of latencies in the AudioFetch Express – Dual Band, AudioFetch App,  and mobile device Operating System only.  WiFi, and mobile device performance can affect latency.  Some Android devices have increased latency.  Use of Bluetooth earbuds will add further latency.

Bandwidth consumed by each audio stream (stereo) 50 UDP packets per second averaging 201 bytes each 

     (includes the IP header but not physical layer header)

Therefore,  UDP (+ IP header) bandwidth is:   

     10050 bytes/sec (average) for each audio stream (~80Kbps)

Discovery and keep-alive control traffic is negligible compared to this

Bandwidth consumed by each audio stream (mono) 50 UDP packets per second averaging 121  bytes each 

     (includes the IP header but not physical layer header)

Therefore,  UDP (+ IP header) bandwidth is:   

     6050 bytes/sec (average) for each audio stream  (~48Kbps)

Discovery and keep-alive control traffic is negligible
