The DT 770 PRO is designed for use in studio and on stage for professional use. The headband has a rugged construction (thicker material) and gives a secure fit for the listener. This provides a better fit and causes also a more powerful compressed sound which is necessary for professional applications in studio, OB and FOH.

Extended information

The DT 770 (Edition 2005) is designed for listening music and relax. The headband provides a long wearing comfort for hours. The Hifi-version has a more transparent and open sound than the DT 770 PRO. The differences of both headphones are not huge in mechanical design, but only that small change causes a big difference in sound and application.

Difference between DT 770 PRO 250ohm and 80ohm?
The transducers of the 80ohm versions are stronger and more powerful, a bit more mid accentuated. The 250ohm version sounds more smooth and voluminous. Normally the 80ohm is louder than the 250ohm version.

The DT 770 PRO 80ohm has a straight cable (3m), it is for the usage as studio monitor headphones – especially for instrumentalists. 80ohm systems are ideal for powerful reproducing of low-frequency material f.e. coming from a bass guitar. The stronger system and thicker membrane provides punchy and clear bass sound at high levels. The DT 770 PRO 250ohm system with its lighter coils sounds more smooth and analytical. The application in studio would here be more in a mixing situation to analyse the whole mix. The coiled cable in this version is ideal to connect the headphone directly to any mixing desk without having any disturbing cable lying on the floor.
