Wireless speaker systems compared

Wireless speakers have long been a Holy Grail of sorts in the home audio world. And while power concerns and still keep the "wireless" aspect firmly in quotes, there's actually been some progress in the past several years. Nearly every major manufacturer offers at least one--if not several--home theater systems with wireless rear speakers. Meanwhile, those with existing speaker systems can opt for universal wireless add-on kits--such as the KEF and Rocketfish models shown below--that convert rear speakers to wireless operation. If you just need a set of stereo speakers, consider the JBL On Air Control 2.4G. And if you're looking for an iPod-friendly wireless system that--thanks to built-in rechargeable batteries--has a set of truly wireless speakers, you'll want to check out the Griffin Evolve.
