The AKG Acoustics IP2 Professional In-Ear Monitoring Headphones provide a wide-range sound with sharply contoured bass reproduction as well as excellent isolation to suppress high ambient noise levels encountered, e.g., on a loud concert stage. An integrated sliding cable tie and the supplied soft-rubber earmolds in three different sizes enable the earphones to adapt to every shape of ear. The IP 2 earphones connect to the SPR 4 bodypack receiver.
