I like Sennheisers. At work I have a pair of HD202s. They're < $25 and sound surprisingly good.

If you're looking for something compact, Koss PortaPros are quite good in the $40 range.

The HD280s are very nice in the $80 range.

If I'm going to go over that price (and I do plan to soon) what's on my wish list is BeyerDynamic DT770 32 ohm. They're $170 so are outside your stated range, but I thought I'd mention them. AKG and Sennheiser also have good contenders in that price range.

When riding (listening to audiobooks/podcasts) I also use the LG Tone bluetooth headsets (using the right earbud only).
