Got the Pro 17’s. Communication, order process, delivery time all perfect. Product is light years ahead of everything else I’ve used in terms of clarity and the seal that they achieve is frighteningly... See more

I got custom made sleep buds

I got custom made sleep buds. Very uncomfortable and sent back. EXCELLENT customer services.

Items returned and the tabs had been cut off. This seemed to be the source of the discomfort. Now one keeps falling out overnight.

Many people seem to be very satisfied so I know I am an outlier on this.

They make my tinnitus 10x worse!

I went to my audiologist in Knutsford. Lovely fella called Roger. He did all the tests and found I’d got 75% mid range hearing, so advised I get some good earplugs for gigs. I promote live music and a musical play so need some good protection.

I wore them last Wednesday at The Blockheads in Liverpool and afterwards my tinnitus was horrific. 10x worse than using cheap sponge earplugs . I thought it was a one off, but have just come back from a gig in Levenshulme, Chris Bridgett, and the same again. There is something wrong - they are clearly filtering out the wrong noise and causing a severe high pitched and very loud spike.

I was not expecting this. Last week I had to sleep with white noise in the background and had terrible night’s sleep, and tonight feels like it will have to be the same.

I’m so disappointed. Whatever they’ve made makes my tinnitus worse, not anywhere near the same normal level. And at £155 it really is a joke.

Excellent Customer Service and Products

I order my second pair of earplugs with ACS for sleeping. The initial pair caused some aching so I reported this back to their customer service. To my surprise, they paid for the postage for me to return them, then made some adjustments which resulted in a perfect pair of earplugs. I have not experience any discomfort with the new pair, and most importantly, it is heart warming to see a company that actually cares about the quality of their products.

Allowing me to enjoy live music and protect my hearing

I bought a pair of ACS earbuds for live music concerts some years ago after attending a concert that was so loud it left my ears ringing for days, and I suspect it caused permanent damage. I am really impressed by how these attenuate the sound level without making it muffled or distorted. I really wish I had bought them sooner and would never now go to a concert without them.

Great product

Great product, not the fastest turn around, but to be expected given they are custom made

I ordered custom made earplugs and the process to get this done was very easy and straight forward. It just took longer for my custom earplugs to be made than the indicated 20 working days. They arrived though and I'm very happy with the product.
