Which one of these is better?

[Ait'al]

Which one of these is better for 3d modeling in your opinion and why. Theyre the same price and i cant figure if one is better than the other, or which one to get eventually.

And of course my final decisions on headphones. I was wondering if someone could help me by telling me some of the differences between them specifically when it comes to how they should perform, And if theres something about them physically that you think needs to be noted go right ahead and post that too.

IM definetly getting one of these. Does anyoen know what the performance difference will be between these? Which one do you think is better?

Does anyone know why the HMD 25-XQ is 349$ and the HMD 280 pro is only 229$? What makes the 25-XQ that much more expensive.
