In spite of the difficulty, it is possible to overcome sound deficiencies in headphones. By using state of the art calibration technology, Sonarworks identifies the differences and calibrates every headphone to perform as close to reference as possible. Sonarworks can squeeze the last drop of performance out of your existing headphones. If preferred, you can buy a new pre-calibrated set. All calibrated headphones receive a unique correction profile that is tailor-made for that particular set.
