At Granda, we specialize in manufacturing and supplying a full range of industrial earmuffs designed to meet the demands of high-noise environments. Whether you're sourcing for factories, construction sites, aviation zones, or manufacturing plants, our earmuffs provide proven performance with lasting comfort.
Noise-induced hearing loss (NIHL) is one of the most common occupational hazards, and it's irreversible. That's why earmuffs aren't just accessories—they're critical components of workplace safety.
Earmuffs are designed to cover the ears entirely, forming a seal that reduces the amount of sound that reaches the inner ear. Their purpose goes beyond comfort—they ensure that your workers are protected from harmful decibel levels without compromising communication or wearability.
Whether your team is exposed to constant engine noise, mechanical impact, or ongoing construction work, the right earmuff makes all the difference in maintaining focus, reducing stress, and avoiding long-term hearing damage.
At Granda, we manufacture earmuffs that meet stringent international hearing protection standards while offering features that prioritize comfort, adjustability, and durability. We help businesses like yours equip employees with dependable gear that performs shift after shift.
When selecting hearing protection, you don't just need a product—you need a partner that understands your requirements.
All Granda earmuffs are engineered for consistent attenuation across mid- and high-frequency sounds. Whether you need earmuffs rated for NRR 22 dB, 27 dB, or 30+ dB, our range includes multiple protection levels suited to different industrial use cases.
Comfort is critical in environments where workers wear protection for 6+ hours a day. Our earmuffs feature soft padded ear cups, adjustable headbands, and balanced pressure distribution to reduce fatigue, skin irritation, or slipping.
We use impact-resistant ABS shells, stainless steel inserts, and PU leather cushions that withstand rough handling, sweat, oil, and extended use. Whether it's for a steel plant or outdoor construction, Granda earmuffs last longer and perform better.
Looking to add your company logo, require a specific color scheme, or need earmuffs that integrate into a broader PPE kit? Our in-house design team supports full OEM/ODM customization, from design tweaks to packaging.
We support large-scale purchasing, and our efficient production capacity ensures we deliver on time, every time. No middlemen, no delays—just factory-direct service, from inquiry to delivery.

Choosing the right earmuff goes beyond checking the decibel rating. Consider the following:
Indoor/Outdoor: Outdoor jobs may require more durable materials or helmet-mount compatibility.
Continuous or Impulse Noise: High-pitched, intermittent sounds (like hammering) may need higher frequency attenuation.
Exposure Time: Longer exposure = more importance on comfort and pressure balance.
Will workers need to wear helmets or glasses simultaneously?
Is portability important (e.g., for mobile maintenance teams)?
Is your workforce highly mobile or standing in place?
If your company wants a unified look across PPE, Granda helps you incorporate color matching, logo printing, and custom labeling—without extra management on your side.
If you're unsure which model fits best, our technical team will help analyze your work environment and suggest the most appropriate earmuff models.

We support FOB, CIF, DDP, and other shipping terms. From container loading to pallet labeling, we ensure your shipment arrives ready to distribute.
Whether you're launching a new PPE line, replacing outdated equipment, or outfitting a growing workforce, Granda is ready to deliver.
At Granda, we know that many of our clients aren't just buying PPE—they're building a cohesive, professional image while meeting regional safety requirements. That's why we offer a full-service OEM/ODM customization workflow that makes it easy to create earmuffs that reflect your brand, your specifications, and your operational demands.
Here's how our customization process works from start to finish:
We begin by understanding your needs. Our team will gather details such as
Required noise reduction level (e.g., NRR 27 dB or higher)
Preferred materials or environmental constraints (e.g., heat-resistant, cold-weather use)
Compatibility with other PPE (helmets, safety goggles, etc.)
Branding goals (color schemes, logo placement, retail packaging)
For international clients, we also discuss applicable safety standards like ANSI, CE, or EN 352.
Once we understand your goals, our in-house designers create a visual mockup. This may include:
Color matching to your company's brand guidelines
Placement options for printed, embossed, or laser-engraved logos
Packaging layout (box, carton, polybag, with labeling if needed)
We'll share renders and confirm specs before proceeding.
Before moving into mass production, we'll send you a physical OEM sample for evaluation. This gives you the chance to:
Check product fit and finish.
Test comfort, durability, and adjustability.
Approve branding accuracy and visual appeal.
We refine based on your feedback, ensuring that what we deliver matches expectations.
Once the sample is approved, production begins. Our earmuff lines are set up for fast transitions, allowing us to handle both small-batch custom runs and high-volume orders. We also offer:
Flexible minimum order quantities (MOQs)
Regular progress updates during production
Pre-shipment inspections and documentation
Customized packaging options include:
Logo-printed cartons
Retail-ready blister packs
Barcoding and pallet labeling
We support FOB, CIF, and DDP terms to meet your import requirements, and we handle all certification paperwork to avoid customs delays.
With Granda, you don't just get a product—you get a partner who takes the complexity out of customization. Let us help you create earmuffs that stand out, perform better, and reinforce your brand every time they're worn.

Different industries demand different levels of noise protection, comfort, and durability. Here's how Granda earmuffs are applied across key sectors:
Construction workers are exposed to high decibel levels from jackhammers, drills, heavy equipment, and demolition. Our helmet-mounted earmuffs are ideal for this setting, offering compatibility with hard hats and vibration-resilient performance. Durable cushions resist sweat and dust, while the design ensures secure placement even with movement.
In warehouses, loading docks, and shipping yards, noise levels can vary but still pose long-term risks. Our standard earmuffs provide reliable attenuation, while remaining lightweight and easy to remove or wear intermittently. Foldable models are popular with forklift operators and mobile workers.
Airside environments involve jet engine noise and tarmac operations. Granda offers high-attenuation earmuffs as well as electronic earmuffs (OEM), which combine noise reduction with communication functionality. These models ensure ground crews stay protected without losing situational awareness.
Mining involves intense noise from drilling machines, crushers, and transport systems. Granda's high-noise earmuffs are designed with reinforced shells, extra-deep cushions, and high-density acoustic foam. Extended use comfort is critical here, so our headbands are padded and adjustable even when worn over helmets.
Assembly lines and stamping operations create repetitive high-frequency noise. Our earmuffs help reduce exposure and fatigue, enabling better concentration and lower absenteeism due to hearing discomfort. OEM options allow integration into company PPE kits with branding consistency.
For military, police, or security training programs, we offer electronic earmuffs with impulse noise suppression via OEM production. These earmuffs protect hearing during gunfire while allowing low-level sounds and team communication — essential for tactical operations.
These industry-specific solutions prove one thing: Granda doesn't believe in one-size-fits-all protection. We tailor earmuffs to match your team's needs — environment, compliance, branding, and usability.
Our team offers guidance at every stage—from selecting the right noise protection rating to finalizing OEM branding.
Let's make sure your team is protected, your brand looks strong, and your procurement runs smoothly.
