High-stereo High Quality Hands-free
Unlike traditional, circular earbuds, the design of the new Apple Handsfree is defined by the geometry of the ear. Which makes them more comfortable for more people than any other earbud-style headphone.
The speakers inside Apple's handsfree have been engineered to minimize sound loss and maximize sound output. So you get high-quality audio that’s just as impressive as what you’d hear from more expensive headphones.
