Choosing your custom earplug
What’s the difference?
Four custom-molded earplugs, each built for a different job. Here’s how to tell them apart in one read — and know exactly which one is yours.

Hear the difference
Don’t take our word for it. Listen.
Press play on a loud room, then switch between the plugs. See exactly how many decibels each one takes off — and hear (and feel) the sensation it produces.
No protection. A loud floor, full force — around 100 dBA.
A simulation of the relative effect — real attenuation depends on your custom fit. Audio plays at a safe, comfortable level; the dBA figures represent real-world loudness.

The One® Filtered
Our patented, university-developed flat-attenuation earplug. Instead of muffling everything, it turns the whole spectrum down evenly — so speech, music, and alarms stay clear while the harmful energy drops. Swap the filter to set your level: 9, 15, 20, 25, or 30 dB.

Full Stop
Maximum sealed silence. There’s no filter path — the custom shell simply blocks. This is the one for sleep, heavy machinery, or any time you want the most reduction and don’t need to hear in. Nothing to adjust, nothing to think about.

Guardian Vanquisher
Multi-layered passive silicone with a 37 dB reduction — the highest custom-molded block Big Ear makes. It tames the report while you still catch range commands, with no batteries and nothing to fail. Built for indoor ranges, big-bore, and high-volume shooting.

Guardian Transformer
A custom communications earpiece that pairs hearing protection with your two-way radio. Your crew stays protected on a loud floor and stays in contact — no trading safety for the ability to hear a call. The go-to for teams that live on the radio.
