Shure WH20-XLR Headset Microphone — Hands-Free Vocal Clarity for Active Performers

The Shure WH20-XLR is a rugged, lightweight dynamic headset microphone for performers who need their voice heard clearly while keeping both hands free. Designed as a successor to the WH10, this model delivers high-quality voice pickup for stage, fitness instruction, multi-instrumentalists, and houses of worship. It is the right choice for active vocalists who need a stable, sweat-resistant headset that connects directly to standard mixers via balanced XLR.

Built for Movement, Tuned for the Voice

What sets this headset apart is its dynamic capsule with a shaped frequency response—there is a voice-frequency presence peak and a low-frequency roll-off to counteract proximity effect during close talking. Greater gain-before-feedback and solid rejection of ambient noise come from the cardioid pattern, while high input clipping level eliminates overload distortion from powerful singers.

Frequency Response & Polar Pattern — Vocal-First Tuning

With its cardioid polar pattern, the WH20-XLR captures speech from the front and reduces background noise from music, drums, or room noise during workouts. Voice-range tuning ensures that vocals remain intelligible even when things get loud.

• Polar Pattern: Cardioid — focuses on the mouth and rejects stage spill for cleaner live mixes
• Frequency Range: 50 Hz – 15 kHz — covers fundamental chest tone and speech intelligibility peaks
• This headset uses a Dynamic capsule to handle loud stages without phantom power, and it resists humidity for dependable use.

Fit, Cable & Connector — Practical Stage Engineering

A comfortable, secure fit is essential for a headset worn for entire performances. The WH20-XLR uses a lightweight wireframe and elastic headband that can be adjusted to any head size, and the boom folds down for storage and transport. The cable is thin yet reinforced to withstand the rigors of touring and frequent use.

• Connector: 3-pin XLR (male) — balanced output plugs directly into any mixer or portable PA input
• Cable Length: 1.22 m — reaches beltpack or mixer without excess slack
• Weight: 63 g — so light, it disappears during long gigs
• Output Impedance: 200 Ohm — designed for reliable long cable runs

Package & Real-World Use — Ready for the Gig

With WH20-XLR, you get a foam windscreen that cuts down breath and wind noise, plus a clothing clip to secure the cable behind your neck. The dynamic capsule requires no phantom power, making it compatible with portable PAs and mixers lacking 48 V supply.

• Package Contents: Windscreen and microphone — clothing clip and removable connector belt clip included
• Power Requirement: None (passive dynamic) — works with any XLR mic input, even battery-powered rigs
• Pairing with a channel that offers enough clean gain is recommended, given its typical dynamic sensitivity of -67.0 dBV/Pa (0.45 mV).

Who the WH20-XLR Is For

This model is ideal for drummers, bassists, guitarists, and keyboard players who sing backup vocals and need a headset that stays put through a set. Fitness instructors and presenters benefit from cardioid rejection of noise, while conference speakers and houses of worship enjoy a discreet headset that keeps the focus on the message. Anyone with a portable rig that lacks phantom power will appreciate the plug-and-play passive dynamic design.

Shure — A Pioneer in Live Sound Microphones

Shure began developing microphones in the early 1930s and is one of the pioneers of the audio engineering sector. Models like the 55 Unidyne (“Elvis microphone”) and the SM57 and SM58 from the 1960s are still found on stages worldwide and hold cult status with musicians and technicians. In the 1990s, Shure introduced its first wireless microphones and in-ear systems, securing its place as a market leader. The WH20 headset line continues this live-performance legacy in a hands-free format trusted around the globe.
