Our Custom In-Ear Monitors are made to fit your ears perfectly, providing a complete seal to prevent sound leakage and deliver the highest quality sound.

ACS Custom in-ear monitors are all about the high fidelity listening experience. Custom fit soft silicone ear moulds create a perfect seal and comfortable fit, combined with state of the art speakers, patent-pending and exclusive technology and our own proprietary crossovers to ensure you are hearing the music as it was intended to be heard.

NEW for 2017! Our redesigned cable and mounting system ensures excellent durability and gives the Custom IEM's a fresh new look.

NOTE: Custom IEM's require impressions of your ears to custom make them for a perfect fit.
The ear impression service is available throughout the UK and is provided free of charge when you purchase a custom-made product direct from ACS.
