MA900, X1 are in your price range. The MA900's comfort is hit or miss as your ears will sit on the drivers, which may be an issue. The X1 is super comfy, but the pads can be itchy for some people. You can also spring for some updated K702s on Amazon which no longer have bumps for around $278, but those require some good power behind them and raises price accordingly. They're pretty stellar for comfort too.
I like the look of the X1's and would like to grab those, unfortunately I haven't seen them on sale yet. What are some good prices for those three I should keep an eye out for?
