Newbie: Broken headphone DT 770 pro

post #1 of 2
Thread Starter 
Hi, Overnight, one of Hearphone speakers stopped working. Days before I noticed a light "fuzzz" sound from them. How would I go? They are out of warranty. DT770 pro 250 ohm. Thanks in advance

the coil inside the driver must have ruptured. Since the rupture is very very small, more like an imperfect electrical contact, there is still some small amount of current passing over. However since the overall impedance of the driver has increased a lot, there will be almost no sound or low distorded sound from that particular driver. This seems to be a common problem with the DT770's. The only real solution is a driver replacement. The new driver must match the impedance of your headphones (dt 770's are made in various impedance models, ranging from 64 to 250-600 ohms from what i remember) .
