Reviews for Filtered Sky Plug

Paul Edwards

Another league
“Finally managed a couple of hundred miles with my new earplugs. Very good, wish these had been available 50 years ago! I’ve used tailor-made earplugs for some years but these are in another league!”

Tiffany Coates

12,000 mile trip from London to Beijing…They were fantastic
“Being a bit slow on the uptake, I finally got myself customised ear plugs (after 14 years of bike travel) and then gave them the ultimate test – riding a BMW 1200GS on a 12,000 mile trip from London to Beijing. Crossing mountain ranges, deserts and some of the world’s busiest cities, I wore the ear plugs every day. They were fantastic, and I can’t understand why I haven’t used them before. They fit me perfectly, I love the colours, and most importantly, they were great at eliminating both the wind and engine noise, particularly important when riding for 11 weeks non-stop. I’m now a complete convert to them.”


Fantastic – Filtered plug
“I’d like to thank you for all your help in purchasing my ultimate ear protection. I have used them flying and they are undoubtedly fantastic at omitting the helicopter noise.”
