Short answer: the Sony SRS-XB13 on battery and price, the Bose Soundlink Micro 2 on outdoor bass. The Sony runs around 16 hours and costs $71 less, but has not much bass and sounds muddy. The Bose survives a 1m dunk for 30 minutes and delivers surprisingly good bass mounted outdoors, though it lacks clarity, its boosted bass thuds and distorts at higher volumes, and its treble is boosted enough that both need EQ cuts. The Sony SRS-XB13 is discontinued; its replacement is the Sony SRS-XB100.
Buy the Bose Soundlink Micro 2. It is rated higher for sound quality, and the Sony SRS-XB13 is discontinued, so it is only available used.
