Looking for closed back headphone advice


So I haven't purchased headphones in many years. I just recently updated my home stereo and am very happy with what I have. However, I'd like to relax with some headphones and I'd like to ask about some good, quality closed back headphones. My budget is around $700. There's only one audio store in town and they don't carry very much and they tend to have poor customer service. I'd like to purchase from a dealer who has a 30-60 return policy in case I don't like them and need an exchange. Any suggestions would greatly be appreciated. Thanks!

If you can pick up a pair of the Oppo PM-3s at a good price, they are very, very good and you can drive them with an I-phone with good results.  They were $399 new and are no longer made, so some people are asking high prices, but check around.  Also, the PM1 and PM2 are great as well, but more expensive.  The PM3s are really great though and fit your criteria very well. 
I want to recommend you Sony MDR-Z1R , cos i bought them and i like them

The Beyer T1 is semi open, but it is a splendid phone.
