AcousticSheep LLC was founded in 2007 by Dr. Wei-Shin Lai, a family physician, and her husband Jason Wolfe, a video game developer. Dr. Lai struggled with getting back to sleep after patient phone calls in the middle of the night. She needed to listen to some meditative music to help her relax. But headphones were bulky, and ear buds were uncomfortable. Since there were no headphones specifically designed for sleeping on the market, she invented her own and called them SleepPhones.
