The great thing about wireless surround sound headphones is the fact that you are not bound to any location because of cords and wires. However, depending on the range your headphone can accommodate, you can even go places with your headphone. There are even wireless connections that can work through walls. These days, there are stereo systems that also include an FM transmitter. Although some of these wireless surround sound headphones can be quite expensive, they’re actually cheaper than wireless surround sound speakers, especially the ones that use a similar technology as that of Bluetooth phones. Sennheiser HD800 premier surround sound headphone is one of the best headphone options around. It features the wireless surround sound technology. Aside from having an excellent sound system, it is also adored for its magnificent look. It offers the most realistic sounds you can ever hear.

Open Vs Close
Open headphones, sometimes marketed as “open air” headphones, have an open grille on the back of the earcup, exposing the driver to the outside and allowing sound waves to propagate away from the ear freely.
Closed headphones have a sealed backing, which attenuates sound waves propagating away from the ear.
It's up to personal choice, I prefer closed headphone for better result. But defiantly they both have different audience altogether.
Generally there is not such difference in any of the model for close or open headphone, if you check this page where close HD 202 headphone is listed for around £ 12 (http://www.best-discount-deals.co.uk/1_4 _buy-and-compare-prices-Sennheiser-HD201 -Closed-Back-Headphones_560800_061510409 6608_0.aspx).
I personally not sure about HD 407 but you can find more information at my blog http://headphones-hifis-earphones.blogsp ot.com/, I have separate posting for HD 202 review, have a look might it help you to make right decision.
The difference between 4xx and 2xx series is the type open and close otherwise there is not much different between the technology and quality between the starting range. But certainly HD 202 was released back in 2006 (if I am not wrong :-)) than 407 should be newer release.
I hope it helps you, please appreciate the answer if it help anywhere.
