"Precisely tailored response and cutting-edge design: a must for all audiophiles. These future-oriented, open-back dynamic headphones do not only offer good wearing comfort but also deliver an incredibly detailed, full, yet crisp sound. This is the result of a new AKG Varimotion two-layer diaphragm that ensures optimum diaphragm motion for extremely accurate highfrequency response and a powerful low end. The overall sound is uncommonly natural and open. In short, the K 601 are premium reference headphones for anyone who appreciates true high-end equipment."
