With a wireless home theater system, the amount of time required to set-up your system is drastically reduced. The wireless speakers in a wireless surround sound system are almost always the rear surround speakers. This has two main benefits: there is no need to try to hide large amounts of wire along the edges of your home theater room, and rear surround speakers are the most forgiving when it comes to sound quality.
The first step in buying your system is to establish a budget. You can spend as little or as much as you want to on home theaters, but like anything else, you get what you pay for. Some home theater systems will cost you as little as $200, but at that price you are sacrificing quite a lot in the sound quality department. Alternatively, you can spend $200,000 and get a system that will melt your ears with sonic awesomeness, but for most of us that is out of our reaches. A realistic budget for a decent quality home theater system would be $400-4,000, depending on what kind of set-up you are looking for.
Once you have a budget, you need to make a decision: will you buy an all-in-one system (a home theater in a box) or buy your home theater components separately. The latter will give you better sound quality and the opportunity to upgrade easily in the future, the former will give you a cheaper price and convenience of set-up.
If you want to get the best bang for your buck, you will need to do some research about your wireless home theater system. There is a wide range of systems available, each with their own advantages and disadvantages. Everyone has different needs, so the only way to figure out which system will be best for you is to spend some time getting to know what's available. Try searching on Google for "home theater review" as a starting point. Make sure you read both professional reviews and reviews by customers who have bought the system. Product specifications are a good starting point, but bear in mind that many manufacturers will manipulate their data so it looks good on paper.
Once you have one or two systems in mind, the next step is to head to your local electronics retailer or home theater store. These will usually have sound rooms that are set-up with several different systems. The store will almost certainly have their own CDs and movies which are chosen because they sound the best on the systems they are selling. Make sure to bring a favorite music CD and DVD (or Blu-ray) to listen to and watch. Home theater is a very subjective experience. You want to make sure that the choice you make will sound good for your listening habits. Find more
After you have made your decision, it is finally time to spend some hard-earned cash and buy your home theater system. The cheapest way to do this is to search online for your chosen system at Amazon.com or similar. Of course, you might want to buy your system from the place that you visited for testing, as a thank-you for all their hard work. The added benefit of buying from a local store is that returns are more easily achieved.
