HEADPHONES AND HEADSETS
First Claim
1. A headset comprising a headband having first and second ends. and first and second electro-acoustic transducers carried at 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 and to the first and the 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, andsome 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.

Abstract
Headphones or a headset comprise a pair of electro-acoustic transducers (1, 2), both ear-pieces and an earpiece and a microphone are carried at opposite ends of a curved headband (3) that is formed by a chain of links (500-511) that are hinged to one another and the transducers (1, 2). Each link (5) involves a shell-casing (8) that on an underside has a first pair of mutually-spaced projecting lugs (9) and has a second pair of mutually-spaced projecting lugs (10) that nest with the first pair of lugs (9) of the next-following link (5). The nested lugs (9, 10) are pierced transversely and pivot pins (11) are inserted in the piercings to establish hinges (7) between the links (5). The transducers (1, 2) are hinged to the ends of the headband (3) to enable the headphones or headset to be rolled up lengthwise of the headband (3).
