ABSTRACT:
An earring for a headset comprising a speaker and possibly a transducer or microphone, is arranged to be worn on one ear of a user so that the earring surrounds the outer ear of the user, and is arranged so that the size of the earring is adjustable. With the object of providing simple adjustment to the size of the ear of the user, the earring is produced with a hard part and a soft part, where the second part can be introduced into the first part. The adjustment of the size of the earring is effected with an adjustment button being secured to the soft part, in that the button with the soft part can be displaced in a channel, which is provided longitudinally in the hard part. The channel is possibly configured by the hard part being configured with a closing part. With the invention an adjustment arrangement for an earring for a headset is thus provided, which is easy for the user to operate, also when the earring is placed on the ear of a user.
