The Heil Sound Pro Set 3 stereo headphones are designed to deliver exceptional audio quality and comfort for SDR (Software Defined Radio), amateur radio, broadcast monitoring, and critical listening applications.

Engineered by Heil Sound — the world leader in communications audio — the Pro Set 3 headphones combine studio-grade clarity with long-wearing comfort, making them ideal for both extended operating sessions and professional audio work.

Featuring 40 mm high-performance drivers, the Pro Set 3 reproduces rich, full-range audio with clear highs, defined midrange, and deep, distortion-free lows. Each earphone is acoustically tuned to provide smooth, accurate sound, ideal for monitoring signals or decoding weak DX stations on your SDR setup.

The lightweight, closed-back design provides excellent passive noise isolation, and the padded leatherette ear cups ensure comfortable, fatigue-free operation. The detachable cable with a 1/8″ (3.5 mm) stereo plug and ¼″ (6.35 mm) adapter makes the Pro Set 3 compatible with virtually any transceiver, audio interface, computer, or headphone amplifier.

Whether you’re decoding digital modes, working SSB DX, or simply enjoying music or podcasts, the Heil Pro Set 3 delivers the clarity, comfort, and build quality that Heil Sound is known for.
