STUDSON ED-2 Ear Defender – 24 dB NRR ANSI Certified Hearing Protection | 30mm Helmet Mount

STUDSON ED-2 Ear Defender delivers essential hearing protection for noisy work environments. With an ANSI-certified NRR of 24 dB, this device helps reduce loud sound exposure, so you can maintain focus on the task at hand while staying aware of your surroundings.

Designed with real-world use in mind, the ED-2 cups are shaped to comfortably envelop the ears, featuring adjustable sliders that let you tailor the fit for a secure feel over long shifts. Soft padding and durable shells contribute to a fatigue-free wear, even through a full day on site.

Effortless helmet integration

The ear defender is built to work with SHK-1 helmets thanks to a 30 mm universal attachment that slides and clips into the integrated slot on the helmet’s side rail. This setup enables simultaneous head and ear protection without extra tools or steps, and it stays secure during movement or climbing between tasks.

• Secure, tool-free attachment that stays in place during work
• Fast on/off transitions between tasks or stations
• Maintains compatibility with other PPE without bulk

Comfort that lasts

Easy adjustment lets you dial in a snug, comfortable seal that covers your ears fully. The result is steady protection without pressure points, so you can wear them through long shifts while staying aware of ambient sounds.

• Adjustable headband and cup positioning for a personalized fit
• Soft, cushioned ear cups reduce pressure and fatigue
• Low-profile design for improved headset compatibility

Durable, dielectric construction

Ruggedly built to withstand dusty, demanding environments, these muffs offer dielectric properties for non-conductive performance in applicable settings. The housing and cushions are designed to tolerate daily wear and exposure to tough job sites.

• Dielectric, non-conductive design for electrical-friendly environments
• Rugged shell and reinforced hinges for longevity
• Resistant to wear from moisture, dust, and impact

Versatile protection across industries

Whether you’re on a construction crew, in a manufacturing plant, or performing field service, the ED-2 provides reliable noise reduction with flexible compatibility. This makes it a practical addition to your hearing protection plan without limiting mobility.
