OSSIC, the San Diego startup building 3-D audio headphones for virtual reality games and other immersive experiences, said it exceeded a crowdfunding campaign goal of $100,000 on its initial day.

A person wearing the OSSIC headphones will hear sounds that seem to come from a certain area, depending on which way that person’s head is oriented.

The business had set a $100,000 funding goal on Kickstarter and had collected about $250,000 in pledges before 9 a.m. Pacific time on Feb. 23, the campaign’s first day. OSSIC’s Kickstarter campaign ends April 21.

The headphones will carry a retail price of $399. Orders for early versions at $199 sold out, with delivery promised in November.

OSSIC is part of the EvoNexus incubator in the University Towne Center neighborhood. Jason Riggs is the company’s CEO.
