Noveto was awarded by the contest
Daimler Startup Autobahn, where the use of this technology was focused on sending personalized audio for pbadengers and the driver in the driver's cab.

Although they aspire to be integrated in various sound systems available on the market, Noveto plans to take its first steps with independent units that look like small transmitters that can be easily attached to televisions, equipment audio or computers, with an approximate cost of 250 to 300 dollars.
