Sanpei Optics makes audio-adaptable eyewear that allows the user to plug in many compatible earbuds into the temple bar on the glasses. They feature a hinge design that allows the user to customize the fit of the glasses to their own face. Sanpei Optics also features its own sets of headphones, including a waterproof pair as well as one with an inline microphone that offers industry quality sound.
The headphones can be used simply to cancel out noise and, when you're finished, the earbuds can be popped out and the glasses can be worn as standard sunglasses. Sanpei Optics currently features two models: I.M.I.O. model (Inspire Me, Inspire Others) which is geared towards the fashion-forward, and G.I.Y.A. model (Give It Your All) which is a more athletic, sporty design.
