A device to deliver a proprietary sound track without wifi or bluetooth

Hi. We are a company looking to deliver a proprietary sound track to our clients. The challenge/opportunity is securing the track, non-downloadable; and delivering it to headphones without a wifi or bluetooth connection. Suggestions are so welcome!


If you are a company, do you have an IT department? If yes, have you asked them what they can come up with?

Have you thought about all clients (Computers) being connected by Ethernet?

We are a small company without an IT expert. Our ‘clients’ are end users of a product we’ve developed, a scientifically validated sleep solution. The challenge is eliminating bluetooth and wifi from sleeping environments, and protecting the IPR. Thank you! Lynnclaire
