Basshead

For closed headphone, I personally feel that the Beyer DT150 is good. Give it a try.

For bass, I really love my DTX50. YOu should give it a try.

If you want even more bass, try the Beyer DTX-50

I have not tried that yet, so no comments But right now I am really loving my DTX50, especially when listening to bass heavy songs

If you like bassy songs, then give Beyer DTX50 an audition at Jaben Network. The bass is I feel that the DTX50 bass is punchy and strong, much better than SF5eb.
