An innovative idea for our customers and environment. Siren is probably the world's first earphone that comes without any accessories in the package. No ear glue, no wire, no protective cover, it is purely a pair of earphones. The brand believes that all purchasers of Siren are all PW Audio confidants, attachaching extra parts to the users who have their own accessories and PW Audio cables is unnecessary. A decision to minimize the waste, and further reduce the price.
