Headphones and headsets

A headset comprising a headband having first and second ends, and first and second electro-acoustic transducers carried at the first and second ends respectively of the headband,

• wherein the headband comprises a chain of links that are hinged in series one to another and to the first and second electro-acoustic transducers at the respective first and second ends of the headband so as to enable the headset to be rolled up lengthwise of the headband into a roll with the first electro-acoustic transducer located centrally within the roll and the second electro-acoustic transducer located on the outside of the roll, and
• some of the links of the chain differ from others of the links of the chain in length lengthwise of the headband in order to facilitate compactness in the rolling up of the headband onto the first electro-acoustic transducer located centrally within the roll, and further
• each link of the chain of links comprises a casing that has a first pair of mutually-spaced pierced lugs that project from one end of the casing for alignment of piercings of the first pair of mutually-spaced lugs with piercings of a second pair of lugs that project from a casing of a next-adjacent link of the chain, and the first pair of mutually-spaced lugs are pivoted to the second pair of mutually-spaced lugs to hinge the first and second pairs of mutually-spaced lugs together.

Headphones comprising a headband having first and second ends, and first and second electro-acoustic ear-piece transducers hinged to the first and the second ends respectively of the headband, wherein the headband comprises a chain of links that are hinged in series one to another so as to enable the headphones to be rolled up lengthwise of the headband into a roll with the first electro-acoustic ear-piece transducer located centrally within the roll and the second electro-acoustic ear-piece transducer located on the outside of the roll, and

• some of the links of the chain differ in length lengthwise of the headband from others of the links in order to facilitate compactness in the rolling up of the headband onto the first electro-acoustic ear-piece transducer located centrally within the roll, and further
• each link of the chain of links comprises a casing that has a first pair of mutually-spaced pierced lugs that project from one end of the casing for alignment of piercings of the first pair of mutually-spaced lugs with piercings of a second pair of lugs that project from a casing of a next-adjacent link of the chain, and the first pair of mutually-spaced lugs are pivoted to the second pair of mutually-spaced lugs to hinge the first and second pairs of mutually-spaced lugs together.

Headphones comprising a headband having first and second ends, and first and second electro-acoustic ear-piece transducers hinged to the first and the second ends respectively of the headband,

• wherein the headband comprises a chain of links that are hinged in series one to another so as to enable the headphones to be rolled up spirally lengthwise of the headband into a spiral roll with the first electro-acoustic ear-piece transducer located centrally within the spiral roll and the second electro-acoustic ear-piece transducer located on the outside of the spiral roll,
• some of the links of the chain differ in length lengthwise of the headband from others of the links in order to facilitate compactness in the rolling up of the headband spirally onto the first electro-acoustic ear-piece transducer located centrally within the spiral roll, and
• each link of a pair of links of the headband located centrally of the chain of links is shorter lengthwise of the headband than some others of the links.
