  • Patent number: 11843908
    Abstract: A remote speaker microphone (RSM) unit enables a user to use either a headset or an in-ear speaker with the RSM unit. The RSM unit includes a first RSM connection for communicating and connectable with the first connection of the headset; and a second RSM connection for communicating and connectable with the second connection of the in-ear speaker. Connecting either the headset or the in-ear speaker to the RSM unit disables the speaker and microphone of the RSM unit. At least one of the first and second connections are wireless, e.g., Bluetooth or NFC, and at least one of the first and second RSM connections are wireless connections communicable with the first and second connections, respectively. In addition or the alternative, at least one of said first connection and said second connection are electrical plugs and at least one of said first and second RSM connections are corresponding electrical jacks.

  • Patent number: 11103021
    Abstract: A headset includes two earcups that overlie and seal around the wearer's ears. The headset includes a system for suspension of the earcups on a helmet, as well as a speaker enclosure that provides increased structural strength without taking up additional space on the board. The headset also includes a battery compartment that can accept either one of two different size batteries to power the electrical components of the headset.

  • Patent number: 11011149
    Abstract: A hearing protection headset that can be worn by a user includes left and right earcups. The headset includes a radio communication system enabling at least one radio signal to be received and played through one or both of the earcups. Noise control circuitry in the headset is configurable by a user between at least three active modes of operation—the circuitry having a first active mode in which the headset provides automatic noise reduction, a second active mode in which the headset provides automatic noise cancellation, and a third active mode in which the headset provides both automatic noise reduction and automatic noise cancellation. A switch is manually operable by the user to configure the circuitry between the first active mode and the second active mode and the third active mode.
