At CES HARMAN showcased the AKG N90Q auto-calibrating, noise-cancelling headphones. TruNote technology is composed of a new, proprietary software solution for auto-calibration and frequency response measurement in combination with a patented, dual-foam ear cushion and pistonic motion driver. The auto-calibration solution uses two microphones in each ear cup in order to measure the frequency response while you are wearing the headphone. This generates an accurate correction filter, all within a second. The dual-foam ear cushion and optimized pistonic motion driver are required to avoid unwanted reflections and cavity effects, deeming both necessary for the optimal accurate sound reproduction.
