The DT880 was pretty underwhelming to me. (I succumbed to the temptation of ending the string of 1-2 word posts)

dt990 was the same^ for me

Absolutely without a doubt PS1000s. I had them for less than a week, couldn't get rid of them fast enough. Definitely my most underwhelming experience with any headphones ever.

This is why you all shouldn't buy headphones because they're cheap or on sale (no offense)

what was it about them that you didn't like

My biggest regret buying headphones was my first can. V-moda CrossfadeLp. I paid full price and i regret that big time. The sound for the money was just not up to par with high quality headphones. Great build quality tho.

Paradigm H15NC... was hoping for that promised Paradigm reference monitor sound and got boomy and bloomy instead, plus non existent noise cancellation, considerable ear pressure, and delaminated foam padding.  Just not at all expected from them, love their MilleniaOne CT system.

... oh and the biggest regretted purchase not because of the sound or comfort or build quality (they are great in all these things) but the fact that they reduced the price in half a few months later... Philips L1.  Comfortable and sound great and are built tough but why did they have to sucker me in at top dollar then totally cut the price?

The Audio-Technica ATH-M30. Granted, they were 80 bucks, but MY GOD are these uncomfortable. I've been trying not to use them since day 1. They're my first monitoring pair though, and I'm gonna get a 200 buck-ish pair very soon.

Focal Spirit One. I almost regretted buying the HE-300, but removing the felt made them one of my favorites.

I actually like these headphones for mobile use with my iPhone, they are by no means great headphones (way too bass-heavy, like Beats almost but not quite) but for the price I paid for them ($60 on Amazon Deal of the Day) they were a great value. Though at the original retail price of $250 there is no way they compare to other headphones you can get for that price.
