Abstract
A communication headset has an earpiece assembly mounted on one end of an arcuate headband having a single-piece integral, unitary construction and a resilient composition. The earpiece assembly includes an earmuff which engages a user's ear and which receives a speaker and speaker holder. The speaker holder is mounted rotatably to an interface module which in turn is mounted to a microphone module. An end cap engages the interface module and the microphone module. The mounting structure for attaching the microphone module to the interface module enables free 360.degree. rotational movement of the microphone module relative to the interface module about a central axis transverse to the interface module. A temple piece is disposed on the opposite end of the headband for engaging the user's temple. The inventive method for making the headband of the headset includes the steps of forming a rigid outer band member by flowing molten thermoplastic material into a mold, and curing the molten material to form a rigid, springy outer band member; transferring the outer band member to another mold; and flowing molten thermoplastic material into said another mold into engagement with the members, and then curing the molten material to form a cushiony inner member fused to the outer member.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
