Well, I don’t know that much about Aluratek, but their new Bump Speaker line looks kind of interesting.
For $50 (USD), you get the AMS01F which is an FM clock radio “boombox” that plays music from SD cards or a line-in jack. It’s got a pair of 3-watt speakers and is capable of running for about 6 hours on single charge. At $80, you get the AUWS01F which comes with a USB dongle that will allow you to wirelessly stream music from your PC or Mac. For $100, the AWS01F comes with an additional remote wireless speaker. You can add on up to 6 remote speakers for whole-house audio if you want.
I like the overall range of the wireless speakers, too. At up to 60 feet, that’s not insignificant. Plus, the price isn’t bad for a wireless speaker system. The only thing that remains to be seen is the overall sound quality of these speakers.
