About Echos Design

echos_logoAt Echos Design, we are always looking to challenge the status quo. We ask ourselves frequently: Why are things designed a certain way and more importantly can we make it better? We take our design inspiration from the design philosophy of Dieter Rams’s 10 Principle of Good Design. We simply want Good Design. Currently we have been working on a Patent Pending product called the Übercaster. It enhances and simplifies local broadcasting. The industry standard medium has been using FM, we want to make it WiFi. No need for dedicated and expensive FM devices, just use your smartphone!

We created a hardware device that WiFi broadcasts Audio in Real-Time and made apps that you and many other people can use your to listen to the audio. Freely broadcast anywhere to anyone audio live!
