February 25, 2007 The evolution of the in-ear monitor. Not long ago, the in-ear monitor was the province of wealthy rocks stars and those in the audio industry. But the MP3 revolution has seen such vast numbers of audio listening devices manufactured that the science is progressing very quickly. We’ve previously written about ROBRADY in relation to the industrial design company’s electric superbike, but this time they’re involved in developing Sleek Audio’s completely adjustable in-ear monitor compatible with state-of-the-art audio equipment, including iPod products. The US$250 SA6 design boasts customized sound (bass and treble options), fit (three use options plus various-size ear tips) and application (replaceable / interchangeable swivel cables), as well as a protective case.
