Short answer: the Tribit Stormbox 2 on price, the Sony SRS-XB20 for a predictable shape. The Stormbox 2 costs $59 less and sounds a little better than the Stormbox 1 with less of a rolled off treble, but its drivers sit on the side, so it still rolls off the treble listened to face on. The Sony’s IPX5 pill shape slides easily into a bag, though it sounds thin at higher volumes.
Buy the Tribit Stormbox 2. It is rated higher for sound quality and still sold new, while the Sony SRS-XB20 is discontinued.
There is a real battery-life gap here: the Tribit Stormbox 2 is rated for 24 hours, the Sony SRS-XB20 only 12 hours.

Tribit Stormbox 2: $70 Amazon eBay
Older model: the Tribit Stormbox (ranked lower, rated 2.8/5).
Pros: A little better sounding than the Stormbox 1, less of a rolled off treble. Keep Xbass on for best frequency response.
Cons: Drivers on the side, so it will have a rolled off treble listening to it face on.
