Sona

The standard pair of earphones. Simple in functionality but solid in their build. These are made to endure. The case of each earpiece is formed by two machined aluminium parts threaded together. One side is rougher, with a coarse sandblasted finish. The other part is polished. It’s an hygienic finish for a component that goes right into the ear. Their form is determined by the capabilities of the simplest machine-milling.
