There are however a few things you need to watch out for when shopping for wireless speakers. Some are listed
Interference Some wireless speakers may interfere with other wireless devices in your house like cordless
phones. A good wireless speaker system will allow you to tune it to a different frequency to overcome these
interferences. Battery life Battery life is not always too great on wireless speakers, as it consumes power to
drive the speakers, internal amplifier and RF receiver.
So, if you want to use your wireless speakers for extended periods of time, it may be wise to make use of the AC
power adaptor. Now this may not always be practical - the whole idea of wireless speakers is to get rid of the
wires. Rechargeable batteries might be the answer and some of the models even come with rechargeable batteries
-something to consider when you need total freedom, even from power outlets.
Range Most wireless speakers can work fine within a range of 150 to 300 feet from the transmitter. (Which would
be located at the source of sound i.e. your hi-fi or computer) The RF frequency is high enough for it to work
through walls and furniture. You do not need a line of sight, but bear in mind that obstacles weakens the signal,
and the more obstacles between the transmitter and receiver, the shorter the range will become.
Weatherproof Outdoor wireless speakers are claimed to be weatherproof, but if you do not need to use your
speakers outside all the time, rather store them inside. This will definitely extend the life of your valuable
outdoor wireless speakers. If you really need to leave it outside all the time, try to find a spot where it can be
hidden from the most harsh weather conditions.
Stereo Not all wireless speaker systems include two speakers to give you a stereo experience. Especially the
outdoor wireless speakers are sold as single units. This can easily be overcome by purchasing two speakers,
obviously doubling the price. Legislation Wireless speakers use RF signals which may interfere with other RF
devices. Make sure that the frequency range is legal in your country. If it is sold by a reputable dealer in your
country, this should not be a problem. Wireless speakers are till a fairly new technology and some still have
issues to be sorted out. So you have to do your shopping wisely.
