When Audio-Technica engineers developed the new SonicPro in-ear monitor (IM) headphones, they centered the design around the three most important components of a superb listening experience: 1) Sound, 2) Fit and 3) Functionality. With its dual balanced armature drivers and a horn-shaped conductor pipe to reduce acoustic radiation resistance, the ATH-IM02 in ear monitor headphones effortlessly deliver that pure listening experience. And the innovation doesn’t stop there – the headphones were specially designed to fit and seal within the ear for the ultimate in-ear monitoring. Each pair comes equipped with three sizes of silicone earpieces (S/M/L) and Comply™ foam earpieces (M) for a customized fit. Detachable cables with formable wire and a carrying case add additional convenience and functionality to the headphones, allowing you to easily take them wherever life takes you.
