"Wouldn't have gone anywhere else other than ACS for my custom in ear monitors. When we found out we were opening up for Westlife, I wanted to get new in ears that I knew would be reliable for our 30 date UK arena tour, and with a few shows already under our belt, I know they won’t let me down."

“The ACS Live! system has transformed my onstage sound with The Rolling Stones. Now I can hear myself above the guitars!!!”

"I've been using ACS products for well over 15 years, initially for hearing protection, and then for IEMs when I started touring with Kylie, my first 'silent stage' production. As a bonus, when I'm touring I now have the nifty little option to dial in from the belt pack a little of the 'ambiance' to bring back that feeling of actually being in the band, something that can be lost with in-ears."

"I needed a clear sounding, comfortable set of in ears for my forthcoming shows with Hans Zimmer. My ACS in ears not only sound amazing, they're protecting my hearing, giving me control over my complete audio environment.. Top service, helpful,knowledgeable, all boxes ticked.. I like the colours too!"

"Absolutely loving my ACS custom in-ear monitors. Serious quality and comfort."
