AcousticSheep LLC designs, manufactures, distributes, and sells the SleepPhones® and RunPhones® brand headphones.


Jason Wolfe CTO Wei-Shin Lai, MD CEO 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.

They worked so well for her that she decided she had to offer them to all of her patients taking sleeping pills. Her husband soldered and she sewed the first 500 pieces themselves on their kitchen table. Initial feedback was phenomenal. One lady was able to come off of sleeping pills after taking them for 10 years. Another saved her marriage because she could finally sleep in the same bed as her snoring husband. Dr. Lai and her husband decided to patent their invention and start a real business. They completely sold out in their first year.

SleepPhones® customers soon demanded a lightweight version for exercising, leading to the invention of RunPhones®. RunPhones are hugely popular for the fitness enthusiast.


AcousticSheep, LLC designs and manufactures soft comfortable headphones in a patented headband design, with an emphasis on using environmentally-friendly materials and manufacturing processes. We strive to use local resources, stay technologically-savvy, and be socially responsible as we create the market for innovative headband headphones.
