Silynx PROTEGO MLD Custom Molded In-Ear Hearing Protection Headset

The Silynx PROTEGO MLD is a custom-molded in-ear hearing protection and communications headset built for operators who require a precision fit. Individually molded otoplastic earplugs made from medical-grade silicone replace standard ear tips, delivering a personalized seal and an NRR of 30 dB. The PROTEGO MLD is available in Black and is compatible with Silynx's CLARUS I, CLARUS II, and FORTIS control boxes.

Built Around Your Ear

The PROTEGO MLD's otoplastic earplugs are manufactured from medical-grade silicone and shaped to the individual user's ear canal. This custom fit eliminates the fit variability of standard ear tips, which matters in sustained operations where an inconsistent seal degrades both hearing protection and audio clarity. Otoplastic earplugs are available in two configurations: with a sound-damping filter, or without. Each configuration can be matched to the user's specific operational noise environment.

Hear-Thru Awareness and Microphone Options

The PROTEGO MLD carries Silynx's Hear-Thru situational awareness technology, allowing ambient sound to pass through while the headset is active. This capability is identical to that found in the PROTEGO PRO. For voice transmission, the headset is offered with either an integrated boom microphone or Silynx's proprietary in-ear "Talking from the Ear" microphone, which captures speech from inside the ear canal without an external mic arm. Both microphone configurations connect to the same modular system.

AUX Jack for External Microphone Expansion

The defining hardware difference between the PROTEGO MLD and the PROTEGO STD is an AUX jack embedded directly in the headset body. This jack provides a rapid-connection interface for Silynx's optional external vest-mounted boom microphones, helmet-mounted boom microphones, and gas mask microphones (all sold separately). For operators who work in environments requiring a gas mask or full-face protection, this interface removes the need to remove the headset to connect an external mic source.

Modular System Compatibility

The PROTEGO MLD connects to Silynx's modular ecosystem via the Quick Disconnect Connector (QDC), the same interface used across Silynx's headset line. Compatible control boxes are the CLARUS I, CLARUS II, and FORTIS. Because the headset, control box, and radio cable are separate components joined by QDC, switching radio platforms requires only a cable change, not a new headset. The PROTEGO MLD is fully compatible with all Silynx modular systems.

Who This Is For and Isn't

The PROTEGO MLD suits military personnel, law enforcement officers, and security professionals who require a custom-fitted hearing protection solution for extended shifts: specifically, operators who need a consistent acoustic seal that standard ear tips cannot reliably provide, and those who need to connect external vest-mounted, helmet-mounted, or gas mask microphones via the integrated AUX jack. Compatible control boxes are the CLARUS I, CLARUS II, and FORTIS.

The PROTEGO MLD is not a standard off-the-shelf headset: it requires individually molded otoplastic earplugs, which are a separate step in the procurement process. It is not rated for immersion beyond IP67 (1 m for 30 min) and is not intended for diving or sustained submersion. External microphones (vest-mounted, helmet-mounted, gas mask) are not included and are sold separately. The PROTEGO MLD does not include a control box or radio cable; those are ordered separately based on the user's radio platform.

Common Questions

What makes the PROTEGO MLD different from the PROTEGO STD?

The PROTEGO MLD differs from the PROTEGO STD by incorporating an AUX jack embedded in the headset body. This jack allows rapid connection to optional external vest-mounted boom microphones, helmet-mounted boom microphones, and gas mask microphones sold separately by Silynx. Both models use the same Quick Disconnect (QDC) interface and are compatible with CLARUS I, CLARUS II, and FORTIS control boxes.

What are otoplastic earplugs and do they come with the headset?

Otoplastic earplugs are individually molded ear inserts shaped to a specific user's ear canal, manufactured from medical-grade silicone. The PROTEGO MLD is designed specifically for use with these molded earplugs, available in two configurations: with a sound-damping filter, or without. Buyers should confirm whether otoplastics are included or ordered separately when purchasing the PROTEGO MLD.

Which control boxes are compatible with the PROTEGO MLD?

The PROTEGO MLD connects via Silynx's Quick Disconnect Connector (QDC) and is compatible with the CLARUS I, CLARUS II, and FORTIS control boxes. Control boxes and radio cables are separate components and are not included with the headset. Changing radio platforms requires only a cable swap, not a new headset or control box.

What is the NRR rating of the PROTEGO MLD?

The PROTEGO MLD is rated at NRR 30 dB. This noise reduction rating applies to the custom molded otoplastic earplug configuration. The NRR reflects the passive noise isolation provided by the medical-grade silicone molded fit; actual protection depends on correct fit and proper molding of the otoplastic earplugs.

Is the PROTEGO MLD waterproof?

The PROTEGO MLD carries an IP67 immersion rating, meaning it is rated for submersion to 1 meter for up to 30 minutes. It meets MIL-STD-810G environmental standards. The headset is not rated for deeper or sustained submersion beyond the IP67 specification.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
