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!
