Fifty years ago, Stephen Ambrose invented the world’s first wireless In-Ear Monitor technology (IEMs). Already a professional musician at age 12, he began modifying swimmer’s earplugs. By mixing in tiny speakers and clay he completed his first In-Ear Monitor in 1965. This was the first time full spectrum high fidelity sound was delivered within a fully sealed ear canal by an In-Ear Monitor. Touring for decades with hundreds of performers including Stevie Wonder, Simon & Garfunkel,Diana Ross, Rush, Steve Miller, Kiss and many others, Stephen perfected and commercialized his IEM designs and was the sole provider of IEMs to the professional market for well over a decade.
