The usual suspects are:
Superlux hd668, hd681, Samson SR850, and other variations
Panasonic RP-HTF600
JVC RX700/RX900
Creative Aurvana Live, when they go on sale on Amazon
If you are a complete basshead, Sony XB500
My personal favorite is the
ATH-T400, but of those I listed, I only own the JVC RX700 to compare. In my opinion, the T400 is clearly superior to the RX700 (but more expensive) and is also under $60. However, I'm like the only person here who owns them.
They are also several other possibilities, but I'm trying to list those that seem to be most frequently recommended in your price level. If you can list musical preferences,and your priorities, people may be able to narrow down the options for you and suggest a few other choices.
