There are many types of wireless speaker systems and each of them comes with its own price. In most cases you will find that they tend to be more pricey that the wired ones. For instance, if you have a player for MP3 or a phone, you will find a wireless speaker with Bluetooth. This will be quite ideal and will help you continue with what you are doing on the table or bed but at the same time be able to enjoy the sound coming from the speaker at the volume that can easily be controlled remotely.
The other categories of wireless speaker systems include Yamaha NX-B02WH which can be got from Newegg.com. Altec-Lansing T515 is another one which can easily be found on Amazon.com. Rocketfish wireless speaker system is another superb speaker being sold even online through BestBuy.com. Suffice to say that these are only but a few categories. There are many other good types.
Don’t be intimidated by the flood of models available. Compare important specs such as maximum range and output power. An outdoor speaker should have larger output power than an indoor speaker so that the sound won’t be drowned out by background noise.
