Selling my IK Multimedia ARC ON•EAR standalone headphone calibration and monitoring system. It is in mint condition, has barely been used, and works flawlessly both technically and optically. This is a game-changer for music production, mixing, and mastering on headphones. It corrects the frequency response of over 250 headphone models completely linear and simulates professional studio monitor environments via its built-in DSP chip. The best part: Once configured, it runs completely standalone on the hardware without any DAW, plugin, or PC/Mac needed – perfect for on-the-go!
