Sub bass specificaly distort significantly earlier than mid bass. Yeasterday i was was watching need for speed movie and then one of three ageras explode. Drivers distorting like crazy at that moment because of very deep bass! Dont know how to put that in english it was rattle or distortion. Does any one experience that on your 990?

Check for hair on your drivers?  I once had a hair on a driver in my DT990s and it was a really bad distortion with deep bass especially.

Thanks mate, i try this but dont think this is the problem, because right out of the box it was doing that. Such a shame because few years ago i wanted to buy these, but got hd598 instead. I was afraid to get a pair of dt990 because many people have experienced rattling... And now i have it... what the hell Beyerdynamic ? They must test all the headphones before selling it!

I have a pair DT990 premium 250ohms. They work perfectly fun except there would be occasionally rattling sound (I'm not sure about the reason for it). If that happens, I just twist my amp few times and unplug my dac from computer and plug it back in. then there is no problems anymore. this has happened 2 or 3 times maybe but I doesn't really bother me because I don't think it's headphones' problems.

I love my DT990 now, It's a great headphone with unbeatable price.

I have same model and ratlling happens at higher wolumes, there is lot of sub bass. Maybe headphones require more power and basic amp just not cut it...

the reason could be that your amp doesn't give enough power to drive 250ohms. I have been using Schiit Magni and modi for a year now. I'm really happen with schiit product. It has incrediable power for big cans. If I ungrade my amp, I will still go for Schiit. I'm using DT990 now, I haven't heard rattling sound for so long, last time the rattling sound happens was couple month ago and I fixed it in a minute.
