The Napier Pro 9 Noise Cancelling Hearing Protection

Effective Noise Cancelling technology without Batteries, Electronics, valves,
or any moving parts!

Unique patented sound chamber technology, directs damaging sounds away from the ear canal, where they are dampened, refracted and cancelled.

The effect is amazingly clear low level sounds such as speech, but with highly efficient protection from damaging noise levels such as gunfire with over 32 Decibels of noise reduction, evenly across all frequencies.

Because the soft comfortable and replaceable ear cuffs seal at the ear but are not inserted into the ear canal, they are vastly more comfortable than sonic, passive or electronic ear plugs.

The lightweight unit is barely noticeable when worn and can therefore be used for long periods without discomfort, vitally important when used by instructors, students, beaters, trappers etc. Normal conversation is possible whilst wearing the Pro 9 and it is slim with no profile below the ear, making it vastly more suited to shotgun mounting that any type of ear muff.

The unit is remarkably light at just 40 Grams 1.7 ounces.

It can be folded and carried in a shirt pocket and is completely weatherproof.

Developed from years of University Auditory research the Pro 9 is a marvel of science at work.
Pro 9 patented technology, completely out performs other hearing protection, with its simplicity and its value, it puts cutting edge hearing protection within everyone’s reach.

I have personally tested this product and they work brilliantly especially for people who do not like the bulk of ear defenders against the stock of the rifles or poking things in their ears
