The Dyson HD07 Supersonic Origin Hair Dryer comes with the styling concentrator adapter as standard. It is therefore not necessary to buy an adapter separately.
The Dyson HD07 Supersonic hairdryer is equipped with a universal plug that is used in many countries, but does not necessarily fit into Swiss sockets. In Switzerland, type J sockets are used, which differ from the sockets commonly used in other countries. It is therefore likely that an adapter will be required to use the hairdryer in Swiss sockets.
