How Silynx Work - One Control Box, Every Radio

The Silynx ecosystem is modular by design. The headset, the control box, and the PTT accessories are separate components - connected by Quick Disconnect (QDC) for seamless swapping. When your mission demands change, you swap the accessory, not the entire system. This modular approach is the single biggest cost-and-logistics advantage Silynx delivers over fixed-cable competitor setups.

Frequently Asked Questions

Still looking for an answer?

The MWPTT (Micro Wireless Push-To-Talk) is a wireless PTT button that pairs with any Silynx control box. It mounts on Picatinny rails - weapons, shields, vehicle dashboards - so you can transmit without reaching for your chest rig.

Yes. The MWPTT features a built-in Picatinny rail clamp for quick attachment to rifles, ballistic shields, riot shields, and tactical vehicles. The MWPTT WR also includes a wired finger PTT for dual operation.

Wired PTTs (U94, Finger/Palm PTT) connect directly to the control box via cable - no pairing needed, zero latency. Wireless PTTs (MWPTT) pair and mount anywhere. Many operators use both: wired as primary and wireless as backup or weapon-mounted secondary.

The Keyfob PTT - it looks like a standard key fob and operates wirelessly. Completely concealed, no visible tactical hardware.

The Silynx PT21 U94 features standard NEXUS connectivity, making it compatible with a wide range of tactical headsets beyond the Silynx ecosystem. It can also be configured with a gas mask adaptor cable.
