I was planning on writing the Eos Wireless iPod Speaker System off as another wannabe Sonos clone, until I saw the price. At $299 for the base station kit, which includes one wireless speaker, and $129 for additional speakers, makes this pretty good value if you're an iPod owner wanting to stream your music around the house. There's also a weatherproof outdoor amp option, for swish garden parties and those times you're locked out of the house due to a bust-up with your loved-ones.
Particularly clever is Eos' mounting system for the speakers - the power-supply is integrated, meaning the unit can mount directly on a wall-outlet without needing brackets, nails or ridiculously strong glue. The wireless technology is apparently "WiFi friendly", by which I assume that it's something proprietary that won't interfere with your network, and you can have up to four speaker units registered to each base-station.
