The Ultra Open Earbuds were designed from the ground up to give you a soundtrack to your life: to let you enjoy your music without blocking your ears, in a shape so comfortable you can almost forget you’re wearing any earbuds at all. The engineering of these earbuds was a matter of squeezing Bose OpenAudio technology – which projects deep, rich sound across a short distance of open space to your ear canal – into a shape that could grip your ear extremely gently, leave your ear open to outside sounds, and contain a long-lasting battery. This design process resulted in the Ultra Open Earbuds’ unique shape, inspired by ear cuff jewellery. The light-as-air flex arm connects the audio portion of the earbud to a battery barrel that goes behind your ear, providing just enough grip to keep the earbuds secure on any size ear.
