Researching about wireless home theater systems can be time-consuming and confusing. To make things easier for you, here are three of the best value wireless surround sound systems currently available for under $400.00.
Panasonic SC-PT760 Wireless Home Theater System

The Panasonic SC-PT760 has 5.1 channel surround sound, with a 5-disc DVD changer. It upscales your DVDs to 1080p ensuring the best possible video experience. The system includes a wireless transmission unit for the rear speakers, which are wired to the rear amplifier.
Panasonic uses a rigid bamboo material in their front speakers, which helps to achieve a clean sound. It is also cool to be able to tell your friends that your speakers are made of bamboo! It has a rather neat flip-down iPod dock, and displays a full iPod menu on the TV screen for easy navigation. The Kelton subwoofer system ensures plenty of bass, and it has VIERA link for those of you with Panasonic VIERA HDTVs.
If you are interested in expanding your audio experience beyond your home theater room, you can have playback in up to three additional rooms with optional purchase of the Panasonic SH-FX85 Wireless multi room audio kit.
The only downside with this system is that it has no video inputs and only 2 audio inputs. For those of you with more complicated setups, this may not be the ideal choice.

Sony DAV-HDX576WF Wireless Home Theater System
The Sony DAV-HDX576WF has 5.1 channel surround sound, with a 5-disc DVD changer and 1080p upscaling. Sony uses its S-AIR technology for wireless transmission to the rear surround speakers, and also includes an S-AIR Airstation speaker. This can be used as a standalone unit in a separate room, allowing for simple multi-room audio functionality.
For those of you with Sony TVs, it has BRAVIA Theatre sync which allows the home theater system and the TV to communicate. It has an iPod cradle, and auto calibration with included microphone. This is a handy feature because it takes some of the guesswork out of calibrating your home theater system.
As with the Panasonic, the only downside with this system is the lack of video inputs. The Sony system has only 2 audio inputs as well, which leaves you high and dry when it comes to more complicated setups.

Samsung HT-Z520T Wireless home theater system

The Samsung HT-Z520T has 5.1 channel surround sound with a 5-disc changer. Like the others, it does upscaling of DVDs to 1080p. In contrast to the other two systems, the HT-Z520T uses 5.8Ghz RF transmission, which means that it is less likely to interfere with wireless phones, and wireless internet.
In the “weird materials for speakers” category it comes up trumps over the Panasonic system, using “green” bio-kelp fibers, which are supposed to reduce distortion. It has an included auto calibration microphone which will help you to get the most out of your system. Like the others, it has an iPod dock, but Samsung also include a USB host with CD ripping which offers you a few more options for playback on your system.
The HT-Z520T has 1 HDMI video input. While 2 or 3 would have been better, at least this will let you easily add in a Blu-ray system if you buy one later on. It is still fairly crippled with audio inputs, with only 2 available.

Conclusion:
There is a lot of value to be had in these sub-$400 systems. You won’t get the latest and greatest features, and there is not a lot of flexibility, but you will get a system that offers basic functionality with very decent sound quality. As you can see, there are more similarities than differences between these wireless surround sound systems. The ultimate choice depends on what you are looking for. All things considered, though, I think the Samsung HT-Z520T is the slightly better option.
