Announced early last month, Denon finally is ready to start shipping its new dual 11.5mm dynamic transducer IEM, the AH-C30 - or as Denon like you to remember, the 'Urban Raver', as this is an IEM designed for the bass loving Hip-Hop listener. The huge housing certainly looks very street-cool, but the important bit is the two big dynamic drivers which are referred as the 'double air compression drivers'. You should be able to find review of the new IEM on a few big review sites (just google), and prepare to pay US$250 if you want one.
