SleepSound custom earplugs are made from an exclusive ultra-soft medical silicone formula and are custom shaped to fit each individual's ear. The custom earplugs go deep into the ear canal and hook onto the ear canal's bend. No matter how much you tumble in your sleep, it can keep a tight fit and won't come loose. Putting it on is like setting the whole world to silence!  With a unique, ultra-thin design, you won't even feel them in your ears while you sleep, so you'll be able to sleep soundly every night for the rest of your life!

An interesting unintended effect is that SleepSound is amazing in noisy living and working environments too! If you're looking for some peace and quiet at work or on a noisy street, put on a pair of ACS SleepSound is like flipping a mute switch.

The typical earplugs in the market usually can't form a good seal with the ear canal, so no matter how many decibels they say they can lower, they won't achieve the desired effect. If you're not wearing custom earplugs, when you tumble in your sleep, the earplugs will loosen up, and finally, they'll fall out of your ear canal entirely! Even if you don't move at all, and sleep on your back because the ear canal is funnel-shaped, the inserted earplugs will slowly slide outwards, and the noise will slowly leak into your ear canal. Eventually, you will wake up from the noise.

We use soft silicone to make custom earplugs because they form a good seal with the ear canal and won't feel like a foreign object in your ears. If the earplugs are uncomfortable to wear, no matter how good the sound isolation effect, you will not be able to wear them. ACS has produced hundreds of thousands of SleepSound earplugs in Europe and other countries for over 25 years. Since entering Taiwan, our customers' reputation has been the market leader, and we believe that SleepSound would satisfy your requirement.

The ACS Swim Plugs provide a fully-fitted, customized ear canal seal to keep water out of your ears while you swim. The Swim Plugs are made of floatable red and blue (right and left, respectively) soft silicone. Because they are buoyant, they will not sink to the bottom of the water and are easy to spot if dropped when they fell into the water.

The ACS Swim Plugs utilize full concha earmoulds, which completely cover the outer ear and the ear canal opening, to prevent the water from directly impacting the ear canal opening when you are swimming. When you swim, you turn your head from left to right the breath. Your ear canals get pulled and change its shape. The soft, comfortable, medical-grade silicone earmoulds follow the ear canal deformations, maintaining a seal to prevent water from entering the ear canals.
