A minimalist spherical shape gives the earbuds a stylish look, and an ergonomic design makes them comfortable and feather-light. Each earbud weighs in at just about 5.6 g and the open-ear design allows ears to breathe, while TPU reduces smudging and staining. The earbuds are interchangeable, with self-adaptive left-right audio channels, meaning you can wear either earbud on either? ear.
