Bluetooth speakers come in at a variety of price points and corresponding quality levels. Some have more features, and others emphasize sound. But sometimes you see such a good deal that it almost doesn't matter what the speaker does. Woot has the Braven 600 Bluetooth speaker on sale today for just $34.99. It's a refurb, but you'll save a lot on a pretty good speaker.
We reviewed it last year and were happy with the device.
