Great attention has also been paid to the small extras of the new earphones. In all three models, the volume can be adjusted easily and conveniently by a volume control integrated into the cable. A small but particularly useful innovation is the variable jack plug. It can be fitted either straight or at a 90-degree angle to ensure optimum connection of the headphones to an audio source. A metal clip with a matching design allows the headphones to be attached to the user’s clothing. Useful travelling accessories such as an aircraft adapter and an elegant carrying pouch put the finishing touches to these highly attractive earphones.
