Expensive ear crusher.

The sound quality is beyond anything I had hoped for. You can actually "feel" the SPL in your head. I use these for critical monitoring and mixing. They do reproduce sound realistically and accurately, and I have no issues with the function of the headphones.

It is great!

Pros

nice head phones with pretty good sound quality. price is okay.

sound quality

none

Great sound, very quiet for headphones (tried various amps no luck) and by far the most comfortable headphones I've ever worn.

Great sound taught me what sound stage is, very quiet for headphones (tried various amps no luck) and by far the most comfortable headphones I've ever worn but due to volume levels and clipping at not even that loud of volumes they weren't right for me.

Beyerdynamic DT 990 Pro Review

Like good-sounding pillows for your ears

Comfortable; Neutral sound; Great detail in mids and highs; Decent soundstage; Price

Lacking in deep bass; Build quality; 250 ohms is something to be aware of
