The DT990 is almost the opposite of the HD600. It is a v-shape, which means emphasized highs and lows, with recessed mids. Not my cup of tea as a main pair, but fun for other genres (and gaming, but I’ll get to that later). The bass hits hard and is great for edm or rock, but it isn’t overwhelming.

Perhaps the AKG K501 (old but really good), K612 Pro et al. The Beyers have a voluptuous bass that muffles the mids especially in fast music.

The DT-880's like the other poster said seemed the most balanced. I've been quite pleased. The DT-770's has a bass bump and were fun to listen to but I couldn't trust them for checking my mixes.The Beyerdynamic DT 770 Pro 32 ohm is one of the larger pairs of headphones on the market and does not fold up at all.
