ACS custom earpieces for broadcasting & entertainment

When you work in a live environment you know the importance of getting things right first time and having things run smoothly...


ACS custom earpieces are used across the globe by security staff, TV presenters, production staff, radio DJs and many more. Ranging from acoustic molds (commonly known as IFB earpieces) to triple driver in-ear monitors we can build a solution to any specification.

Using custom earpieces instantly makes the user feel more secure. It improves the quality and isolation of the sound, fits so comfortable you can forget you're wearing it and 

looks so discreet that nobody will see it. When there’s an important job at hand, you need to rely on your earpiece, whether it’s for producers instructions or protection from loud crowd noise. During physical activity, ACS custom earpieces stay put and offer unprecedented comfort that allows you to work unhindered for a long period of time.

Uniquely, our PRO series earplugs also allow you to turn your earplugs into radio communication earpieces simply by removing the attenuation filter and inserting the acoustic tubing of an existing earpiece or our T15 IEMs. A solution perfect for security staff that need to isolate the radio instructions but also hear outside noise, but at a reduced protected level. This exact solution is used by Madison Square Garden security and was instrumental to the staff of the Coca Cola Olympic torch relay in Britain during the summer.




Key features to using ACS custom earpieces:

-       Compatible with most radio systems  -       Made from soft silicone material to increase comfort

-       Carefully selected balanced armature drivers for clear and precise audio playback

When I'm presenting on a live show I rely heavily on my custom ACS earpiece. In any live show there's always a lot of moving parts. From the roar of the crowd to my interview guest standing right next to me talking in my ear - its imperative that I can communicate with my director, producers and gallery clearly and without interference.

Every occupation has its tool of choice. Like a plumber needs a wrench or a doctor needs a scalpel - presenters need an earpiece. Its our lifeline to the production team and on a live show you don't get second chances to hear a direction from the gallery or an update from your producer. You have to hear it first time and my ACS custom gives me the clarity and volume I need.

It fits securely, discretely and more comfortably than any other earpiece I've used and isolates exactly what I need to hear.

On a complex project like the Olympic torch relay clear communications across the teams is key, especially in noisy environments. ACS were great to work with and provided a perfect solution that fitted the project and kept the team connected, my thanks to the team at ACS’
