It will help people steer you in the correct direction if you tell us what kind of music that you mostly listen too. That will help us make good suggestions. So we know to be talking about open back, semi-open, or closed back. Also you may want to include how you are driving them. As some cans sound way better with a separate headphone amp. Also you should note if these will be for only home use or if you are traveling with them as well. And also are you only in the market for vintage headphones or are modern ones okay? Disregard the below information if you are after vintage phones.
I will list a few that I feel are good value cans inside your price range though.
Audio Technica ATH-M50s: These are wonderful all around headphones. I think they do an awesome job at replicating accurate neutral sound. The bass they have is realistic and tight. Not boomy and muddy. These can easily be found for less than $150. Easily driven from everything from an iPod to your home stereo.
Sennheiser HD 558: Very nice open back headphones in your price range. New for $180 on Amazon, or there are several used pairs in "like new" condition for around $100. If you listen to a lot of jazz or vocal music these sound great. These sound good with a lot of other styles of music as well open-backed headphones typically standout with jazz and vocal music though.
Grados SR 225i or 125i: Grados makes some wonderful sounding headphones. With their open backed design they really sing pretty. Only flaw with them IMO is comfort. These definitely take some getting used to with the on-ear design. Also some people find the bass to be a little underwhelming.
IMO as well stay away from the Bose noise cancelling ones unless you do a lot of airplane traveling. I have a set of the Bose QC-15s and they block out noise very well. However I do not feel they play music nearly as well as the Audio Technica, Grados, or Sennheisers. Plus they are over twice the price. I have the Audio Technica ATH-M50s and modded Grados to compare them to.
Hope I helped you with a place to start. If you have any questions feel free to PM me as I am bad at checking the different threads that I post on.
Take care and good luck in the hunt,
Josh
