LTB Audio Systems has pioneered patented acoustic design technologies to bring you the true nuance of surround sound in a headphone. Our patented tri-chamber ISC system ensures the correct report of audio tracks in all forms of digital media. By chambering our speaker/emitters we can enable the proper positional sounds to be accepted by the ear in conjuction with real time encoding as the media was intended to produce. Only LTB has patented ISC developed to reproduce true 5.1 surround sound just like a home theater audio system costing hundreds to thousands of dollars.
