I've had some dt 770 pro's for possibly a year now, which have been great until the last month or so.
I use them a lot watching TV at night, and they now make a noise every time I breathe in and out! This sounds random so i'll try my best to explain.
I've figured out that when I breathe in/out, the ear pads must move slightly, but due to the velour material, and their closed design, it makes a really noticeable friction/squeeking noise. If you wanted to simulate the noise, to better understand what i mean, put the 2 earcups together and rub them together, its exactly this noise, but amplified when they are on your head.
I find it strange, as there it is very minimal movement breathing in and out!
Has anyone else experienced this problem? Is there anything I can do to try and fix it? Could I tighten it up in any way?
Any help would be much appreciated.
