Bluetooth Connectivity
DISCUS
Bluetooth Adapter for Military Headsets
Add phone calls, music, and apps like SIGNAL and Zello to your tactical headset. Runs standalone or in-line with a PTT — radio traffic is always prioritized over Bluetooth audio.
Made in USA
How It Works
DISCUS sits between your NATO-wired headset and your comms chain. Pair it to a Bluetooth device for phone calls, media, and push-to-talk apps — or use it alongside a two-way radio and PTT. Intelligent audio priority automatically elevates radio traffic over Bluetooth so critical traffic is never buried under phone audio.
Standalone Bluetooth
Headset → DISCUS → phone or tablet. Make calls, listen to music, or run SIGNAL / Zello without a radio in the loop.
With PTT + Radio
Headset → DISCUS → PTT → radio. Radio TX/RX takes priority; Bluetooth fills the gaps between radio traffic.

Compatibility Notes
-
Dynamic mic required. Electret and amplified boom mics will not work with DISCUS.
-
Not compatible with TCI-style TP-102 plugs due to connector size limitations.
-
Not compatible with Constant Able’s auto-sensing path for electret. DISCUS is a dedicated dynamic-mic Bluetooth adapter; Constant Able remains the multi-mic PTT solution.
