25-197 Heil ProSet Elite
The Heil ProSet Elite is a premium boom-microphone headset designed for amateur radio operators, contesters, and broadcasters, offering exceptional transmit and receive audio quality with comfort for long operating sessions.
🎧 Headset Design
Dual-Sided Speakers: Highly efficient drivers mounted in acoustically tuned chambers for clear audio and strong rejection of outside noise.
Phase Reversal Switch: Unique Heil feature that reverses the phase in one earcup, creating a spatial widening effect. This makes signals easier to pick out in pileups and reduces listener fatigue.
Comfort: Large round ear pads with removable cotton covers (washable), cushioned headband, and fold-up design for storage.
Cable: 6 ft coiled cable with 1/8" mono plug for microphone and 1/8" stereo plug for headphones.
🎙 Microphone Options (not known which element is installed):
HC-6 Dynamic Element: Wide-range response, sensitivity -57 dB, 600 Ω impedance. Can be equalized for broadcast-quality or narrow contest audio.
iC Electret Element: Tailored for ICOM rigs, requiring bias voltage, ensuring proper drive levels.
Noise Rejection: Closed-ear design blocks ambient noise, ideal for contest stations or noisy environments.
Durability: Rugged boom, replaceable ear pads, washable covers.
📌 Summary
The Heil ProSet Elite combines high-fidelity receive audio, contest-grade transmit clarity, and long-wear comfort. Its phase reversal feature is a standout tool for DXers and contesters, while the choice of HC-6 dynamic or iC electret mic elements ensures compatibility with a wide range of radios.
Udo, for NS9RC auction listings, you’ll want to emphasize:
“Broadcast-quality audio with phase reversal for pileups”
“Two versions: HC-6 for modern rigs, iC for ICOM radios”
“Comfortable, washable ear pads and rugged boom mic”
That combination will catch the eye of contesters and DXers looking for a serious headset upgrade.
