San Francisco — SOL Republic introduced its Shadow Wireless in-ear headphones on Tuesday.

Kevin Lee, CEO and co-founder of SOL, previewed the lightweight headphones to TWICE during International CES in January, and said the company had designed them to be worn all day long, resting on the person’s neck when not in use.
