Absolutely 100% would recommend ACS to anyone and everyone. They were great about 8 years ago when I was on the look-out for custom earplugs and came through gloriously when I found they did IEM's too and a great customer services to go with it.

A great professional service from start to finish, everything when smoothly and delivery was faster than expected. The ear plugs fit perfectly and very comfortable to wear during the night resulting in a much improved nights sleep.

Super efficient bespoke ear plugs that do a great job of eliminating noise whilst being able to hear the bike and use the intercom. The whole order process was clear and easy to follow. I would highly recommend ACS to anyone needing to prevent hearing damage!

I love ACS! They have saved my hearing over 20 years of working in the music industry. I won't DJ or go to gigs without my filtered plugs. And their solid silicone plugs give me a better (quiet) night's sleep. The whole ACS team are genuinely lovely people too - is there a six-star option?!

It is obviously a bit more effort than your average purchase to go out and get the moulds measured. However the end product is very much worth it. Most comfortable and effective ear plugs I have tried. (And I have tried many.) Several excellent night's sleep so far next to my snoring husband.

ACS are the absolute best. Not only are their products amazing but when there has been a problem (down to my weird ears, not their product!) they have gone over and above to sort it out - far beyond what I would expect, and lightyears ahead of any other UK customer service. Simply incredible.

ACS are the best in the biz… recognised as the top brand in the industry, yet they remain humble & dedicated to providing the best products & service. Helpful & informative right thru the process & the result is the best on stage sound & unrivalled comfort & fit when wearing for long periods of time.

Very pleased with this company, had an enquiry which was answered promptly. Have now received my sleep sound earplugs which fit perfectly and the whole process from having the ear impressions done and receiving them took only 3 weeks.

Easy to order online, being able to get the moulds of the ear done locally, quick turn around after the moulds were sent off. Kept informed when they were posted out and the courier delivered on the date they said they would arrive. I would have no hesitation in recommending ACS.

Ordered a new pair of Pro27’s using my impressions already held on file. Simple process from start to finish, quick turnaround, new set arrived and still fit perfectly. Excellent quality, really work very very well, looking forward to many more hours of protected riding.

This is my second purchase of custom moulds from ACS, and the service was as great as the first time (which is why I came back a 2nd time). I called them for more information on their products and they were very helpful, allowing me to make the right choice for what I needed. Thank you for a great product.
