The Point Source Audio CM-i3-4F Intercom Headset with XLR-4F Connector for Clear-Com Systems is a modular intercom headset designed for concert venues, front of house operations, multimedia production, and other professional trades that rely on convenient two-way communication systems. The headset allows for three different listening modes. Instead of having to remove the entire headset to check sounds in the environment, the user can simply remove one or both of the earphones.

For modularity, they feature the company's EM-3 in-earphones which can be switched with earphones of the user's choice. The flexibility also extends the serviceability and lifetime of the product. The headset has a boom moving coil dynamic element with a cardioid pattern and a frequency response of 300 to 10,000 Hz. The earphones feature a single driver ported design and come with three sizes of eartips, a windscreen with an o-ring, and a custom storage case.
