Abstract: A headset includes an earpiece with a speaker and a speaker port connectable with an eartip for insertion in an ear. The headset further includes an earhook with a first end coupled with the earpiece, a second end, and a length extending therebetween. The earhook has a transverse cross section along the length. The transverse cross section has a major cross dimension and a minor cross dimension orthogonal to the major cross dimension, the major cross dimension being greater than the minor cross dimension. A cable and a support wire are connected to the earpiece and embedded in the earhook along the length. The cable may include one or more electrical wires connecting the components of the earpiece to a device.
