The models of the PRO product family (DT 770/880/990 PRO) are designed for professional users while those of the Edition product family are designed for music enjoyment at home or on the go.
It is important to know that the models of the PRO and Edition product families do not differ noticeably in terms of sound, provided that they have the same impedance (e.g. the 250 ohm DT 880 Edition and the 250 ohm DT 880 PRO sound the same).
