C4OPS
The Silynx C4OPS is a modular tactical headset system designed for special forces, infantry, and elite military operators. It combines an in-ear headset with an ambidextrous push-to-talk (PTT) control box to deliver clear two-way radio communication, in-ear hearing protection, and Hear-Thru situational awareness in one rugged, helmet-compatible package.
As Silynx's first-generation sound-protection radio controller, the C4OPS established the foundation for the company's tactical communications lineup. It has since been succeeded by the Clarus family and Fortis lines, which build on its proven architecture with expanded capabilities and updated features.
C4OPS is rated to MIL-STD-810 with IP68 immersion to 10 meters and is compatible with virtually every major tactical radio in service, including MBITR / PRC117 / PRC152, Motorola APX, Kenwood, Harris XG-75, and Hytera. It is in service with US, NATO, and Israeli special operations units.

What is the Silynx C4OPS?
The C4OPS is Silynx's first-generation modular tactical headset system designed for special forces, infantry, and elite military operators. It combines an in-ear headset with an ambidextrous PTT control box for clear two-way radio communication, hearing protection, and Hear-Thru situational awareness.
Is the C4OPS still in production?
The C4OPS has been succeeded by the CLARUS family and FORTIS lines, which build on its proven architecture with expanded capabilities. However, the C4OPS remains in active service with US, NATO, and Israeli special operations units, and cable adaptors and accessories are still available.
What radios is the C4OPS compatible with?
The C4OPS is compatible with virtually every major tactical radio in service, including MBITR/PRC117/PRC152, Motorola APX, Kenwood, Harris XG-75, and Hytera. Note that C4OPS uses its own cable adaptors — CLARUS and FORTIS cables are not interchangeable with C4OPS.
What are the durability and environmental ratings?
The C4OPS is rated to MIL-STD-810 with IP68 immersion capability up to 10 meters.
Can I use CLARUS cable adaptors with my C4OPS?
No. The C4OPS uses its own dedicated cable adaptors (such as the C4OPS 5-Pin Cable Adaptor and Peltor/Sordin Adaptor). CLARUS and FORTIS cables are not compatible with the C4OPS system.
Should I upgrade from C4OPS to a newer Silynx system?
Silynx recommends the CLARUS I, CLARUS II, or FORTIS QUAD PTT for all new procurements. These newer systems offer additional communication networks, advanced features like Drone Detection and Pre-Recorded Messages, and expanded modularity. Transitioning from C4OPS requires new cable adaptors matched to your new system.
Is the Silynx C4OPS ITAR / export controlled?
Yes. The C4OPS system is subject to US export regulations. International buyers must work with Silynx on export compliance before shipment.
What's included with the C4OPS?
The kit includes the C4OPS PTT control box, in-ear headset, foam ear tips (S/M/L), M.O.L.L.E. mounting clip, and your selected radio cable connector.
Can the C4OPS be used with weapon-mounted PTT?
Yes. The optional MWPTT wireless PTT attaches to a Picatinny rail and lets the operator transmit while keeping both hands on the weapon.
