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 $50.01 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.
Buy the Bose Soundlink Micro 2. It is rated higher for sound quality, and the $50.01 saving on the Sony SRS-XB13 is not enough to make up the difference.

Sony SRS-XB13: $78.99 Discontinued Amazon eBay
Newer model: the Sony SRS-XB100, ranked higher, rated 2.9/5.
Pros: Sony SRS-XB13 uses 46mm. Its 255 g, claimed 16 hours (Manufacturer specified) battery life, IP67 protection, up to 88dB and mono playback make it a practical option for its intended room or portable use. A removable strap hangs it from a bag or bike. Measured bass extension of 88Hz (-10dB).
Cons: Bass is limited by its 88Hz specification. There is no companion app. No EQ adjustment. Not much bass, and the sound is muddy. Discontinued.

Bose Soundlink Micro 2: $129.00 Amazon eBay
Older model: the Bose Soundlink Micro (ranked lower, rated 3.5/5).
Pros: IP67 rated, survives a 1m dunk for 30 minutes. Compact fabric strap for clipping to bags/bikes - replaces the 1st-gen’s hook clip, which was prone to breaking. USB-C charging. Surprisingly good bass when mounted outdoors, like on a bike.
Cons: Lack of clarity. Overly boosted bass that causes some thudding, and can overdrive/distort at higher volumes - worse in this regard than the 1st-gen model. Overly boosted treble, turn down bass and treble in the EQ. Falls clearly behind the Tribit Stormbox Micro 2 on bass depth, cleanliness, and loudness.
