Abstract
Abstract An earphone is disclosed in which the headband is pivoted to the earpieces so that the headband can be worn either over the top of the head or under the chin while the earpieces remain in position so that the cables come out the bottom and do not become kinked.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
An earphone comprising two earpieces, two cable connectors respectively carried by said earpieces, a spring band carrying said earpieces so that they are symmetrically disposed with respect to a plane of symmetry, and means connecting said spring band to said cable connectors for relative rotation through an angle of at least 120* in planes which are at least approximately parallel to said plane of symmetry, each of said earpieces and the associated cable connector forming a unit to which said spring band is rotatably connected, said spring band being pivoted to each of said units by a pivot which is disposed inside said unit.
Claim 2
Dependent Claim
104 words
An earphone comprising two earpieces, two cable connectors respectively carried by said earpieces, a spring band carrying said earpieces so that they are symmetrically disposed with respect to a plane of symmetry, and means connecting said spring band to said cable connectors for relative rotation through an angle of at least 120* in planes which are at least approximately parallel to said plane of symmetry, each of said earpieces and the associated cable connector forming a unit to which said spring band is rotatably connected, said spring band being pivoted to each of said units by a pivot which is disposed inside said unit.
Claim 3
Dependent Claim
86 words
An earphone which comprises two earpieces, two cable connectors respectively carried by said earpieces, a spring band carrying said earpieces so that they are symmetrically disposed with respect to a plane of symmetry, and means connecting said spring band to said cable connectors for relative rotation through an angle of at least 120* in planes which are at least approximately parallel to said plane of symmetry, each earpiece and the cable connector carried by it being connected to said spring means for independent rotation relative thereto.
Claim 4
Dependent Claim
86 words
An earphone which comprises two earpieces, two cable connectors respectively carried by said earpieces, a spring band carrying said earpieces so that they are symmetrically disposed with respect to a plane of symmetry, and means connecting said spring band to said cable connectors for relative rotation through an angle of at least 120* in planes which are at least approximately parallel to said plane of symmetry, each earpiece and the cable connector carried by it being connected to said spring means for independent rotation relative thereto.
Claim 5
Dependent Claim
93 words
An earphone which comprises two earpieces, two cable connectors respectively carried by said earpieces, a spring band carrying said earpieces so that they are symmetrically disposed with respect to a plane of symmetry, and means connecting said spring band to said cable connectors for relative rotation through an angle of at least 120* in planes which are at least approximately parallel to said plane of symmetry, each of said cable connectors being connected to the earpiece carrying it for rotation about a point which is spaced from the center of the connected earpiece.
Claim 6
Dependent Claim
93 words
An earphone which comprises two earpieces, two cable connectors respectively carried by said earpieces, a spring band carrying said earpieces so that they are symmetrically disposed with respect to a plane of symmetry, and means connecting said spring band to said cable connectors for relative rotation through an angle of at least 120* in planes which are at least approximately parallel to said plane of symmetry, each of said cable connectors being connected to the earpiece carrying it for rotation about a point which is spaced from the center of the connected earpiece.
Claim 7
Dependent Claim
33 words
An earphone as set forth in claim 3, including an arm carrying a microphone and connected to one of said cable connectors for rotation therewith relative to said earpiece carrying said cable connector.
Claim 8
Dependent Claim
25 words
An earphone as set forth in claim 3, in which said spring band is pivoted to each of said earpieces approximately at the center thereof.
