Shure WH20 Dynamic Headset Microphone: Comprehensive Product Manual

Introduction to the Shure WH20 Dynamic Headset Microphone

The Shure WH20 Dynamic Headset Microphone is a rugged, lightweight, cardioid dynamic headset mic engineered for high-quality voice pickup in demanding environments. Ideal for active users like aerobics instructors, musicians, and stage performers, this headset microphone ensures secure fit with its adjustable lightweight wireframe and elastic headband, accommodating any head size or shape. Its low-visibility design makes it perfect for stage appearances where mobility and reliability are essential.[1][2][3]

Key benefits include a smooth, natural frequency response from 50 Hz to 15,000 Hz, comparable to high-end handheld vocal mics, with a voice-frequency presence peak and low-frequency roll-off to counter proximity effect. The cardioid polar pattern delivers superior gain-before-feedback and isolation from ambient noise, air conditioning, or instruments. Additional features encompass an extra-strong small-diameter cable resistant to breakage, collapsible microphone boom for easy storage, high input clipping level to prevent overload distortion, and reliability across temperature extremes (0° to 140°F operating) and humidity (0-95%). It comes supplied with a foam windscreen, clothing clip, and model variations like WH20QTR (1/4-inch plug), WH20TQG (TA4F for Shure wireless), and WH20XLR (XLR connector).[1][2][3][4][5]

Target audiences include fitness professionals, live performers, and voice communication users needing hands-free operation. Use cases span aerobics classes, concerts, presentations, and wireless systems. Priced typically between $100-$150 depending on the connector variant, the Shure WH20 Dynamic Headset Microphone is widely available from retailers like Sweetwater and American Musical Supply, with free shipping options on orders over $50 and 30-day returns.[3][6][7]

Troubleshooting the Shure WH20 Dynamic Headset Microphone

Common issues with the Shure WH20 Dynamic Headset Microphone often stem from fit, cable wear, or environmental factors. If no sound is produced, check connections: ensure the 3-pin XLR, 1/4-inch plug, or TA4F matches your system, and verify polarity (positive pressure on diaphragm yields positive voltage on pin 2 vs. pin 3).[1][4] For low volume or feedback, adjust the collapsible boom to 1/2 inch from mouth for optimal close-talk response, and use the included foam windscreen to reduce wind noise or plosives.[1][2]

Cable breakage can occur with heavy use; inspect the extra-strong small-diameter cable and secure with the clothing clip. If distortion arises, confirm input clipping level suits the -67.0 dBV/Pa sensitivity (0.45 mV at 1 kHz). No specific error codes apply as it's a passive dynamic mic, but hum sensitivity (38.4 dB SPL equivalent) may indicate interference—position away from AC fields.[1][4] Preventive measures: Store collapsed in protective cases, avoid extreme storage temps (-29° to 165°F), and clean windscreen regularly.[1]

Shure offers a standard 2-year warranty; contact Shure support via their website or expert tech support at retailers for replacements. For help, visit shure.com or authorized dealers like Sweetwater for extended 12-month warranties.[3][7]

Exceptional durability: Extra-strong cable resists breakage; reliable in humidity (0-95%) and temps (0-140°F operating).[1][2]
Superior audio quality: Cardioid pattern rejects noise, 50-15kHz response with presence boost mimics handheld vocals; high clipping level prevents distortion.[1][4][6]
Versatile and portable: Collapsible boom, multiple connectors (XLR, 1/4", TA4F), includes windscreen and clips—weighs just 0.137 lbs.[1][3][5]
Great value: At $100-$150, outperforms budget headsets in feedback rejection and longevity compared to Audio-Technica BPHS1.[6][7]

Cons

Fixed cable length: Attached cable may limit some wireless setups without adapters.[1]
No on/off switch: Always hot when connected, requiring mixer muting for passive use.[5]
