Sony SRS-XB100: $63.00 Amazon eBay
Older models: the Sony SRS-XB13 (ranked lower, rated 2.8/5) and the Sony SRS-XB12 (ranked lower, rated 2.5/5).
Pros: Long real-world battery life (~17 hours in testing). IP67 rated and pocketable at 267g, with a clip for bags/gear. Can stereo-pair two units.
Cons: Not much bass. Seems pretty much the same as the XB13, maybe a teeny bit deeper bass and a little less muddy.
