A series of intercom headsets from Point Source Audio that employ their patented design. The headset weighs under 57g which allows the user to wear for a longer period of time without fatigue. The connected in-earphones are detachable via MMCX connectors, allowing the user to change to their own preference of earphone.
CM-i3 Dynamic microphone
Designed as a comms headset for use in concert venues, front of house operations, multimedia production and other professional trades relying on convenient two-way communications, CM-i3 incorporates dynamic microphone capsule with 12dB off-axis noise rejection - positioned on a flexible boom; and EM-X in-ear earphones. The cables that run from the headset frame to the termination are enclosed in a cable wrap that allows users to change the full earphone system if preferred over changing the in-earphones alone via MMCX connection.

CM-i5 Condenser microphone
CM-i5 is also designed for professional use in front of house operations, in concert venues, and has the same functional and earphone properties as CM-i3, however it includes a back-electret condenser microphone that requires bias voltage. The microphone retains the cardioid pickup pattern with noise-cancellation properties.

CM-PTT-M1 Push-to-talk switch
CM-PTT-M1 has been developed to merge two communication systems into one device. This connectivity addresses a common challenge across multiple industries: the need for an integrated solution supporting rapid and reliable communication whilst allowing active listening on two systems.
The device is connected to the CM-i3 or CM-i5 headset via the first of the two XLR connections of the fixed Y-cable. The second XLR connects to the intercom body pack, and the 2-pin connection with coiled cable connects to the Motorola M1 device. Adapters for connectivity to M4, M7, and M9 radios are available to order.
Compatible with a wide range of Motorola radios, including CP, CLS, DEP, DTR, GP, PR, RDU, RDV, SP, VL, XV/XU, XT, and XTN models with M1 connector. This compatibility ensures that users can maintain seamless communication with diverse systems, enhancing efficiency and coordination in fields such as construction, security, and event management. Point Source Audio suggest users check with the radio manufacturer to gain detail of exact compatibility before purchasing.
