Soundcast SpeakerCast

 Soundcast's SpeakerCast is a multimedia speaker system with two 3" drivers housed in a small portable box case. Along with portability, one of its main features is that it streams music from various sources using its (included) wireless transmitter.

The transmitter can connect directly to an iPod, but it can also receive input from an auxiliary I/O port. The transmitter works within a 150-foot range, even through doors, walls or ceilings. The speaker itself has a remote control, with track skipping and volume buttons that eliminate the need to use the media device. The same controls are also right on the speaker box itself. Also, the transmitters automatically search out unused frequencies to avoid potential interference with other devices. The speakers are powered by a built-in 50W amp.
