There are two versions of the DT 770 PRO models that have different membranes and coils.
The models with 600 ohms, 250 ohms and 32 ohms have a hanging coil with a lower winding height that is connected to the membrane using a supporting carrier. The suspended coil locates only in the magnetic gap during running mode.
The DT 770 PRO models with an impedance of 80 ohms and 16 ohms, however, have a driver with an overhanging coil that sticks out of the magnetic gap and is directly connected to the membrane. So there is no need for a support for the coil in the magnetic gap. Basically, the resonating mass of our overhanging drivers is higher than that of the suspended models. Therefore, the overhanging driver require a slightly thicker membrane.
In terms of sound, the impedance variations differ in the treble and bass range due to the different coil dimensions as well as the different membrane thicknesses. Compared to the overhanging models, the DT 770 PRO headphones with a suspended coil sound a little more brilliant or present whilst also having a slightly more pronounced bass range.
