Short answer: the Bose Soundlink Micro 2. It ranks #18 of 62 small speakers by sound quality (rated 3.6/5) at $129 and is still sold new; the Sony SRS-XB12 ranks #53 (rated 2.5/5) and is discontinued, so it is only an option used. The Sony SRS-XB12’s replacement, the Sony SRS-XB100, is rated 2.9/5 at $44.
The Bose Soundlink Micro 2 is the better-sounding pick. IP67 rated, survives a 1m dunk for 30 minutes. It supports aptX Bluetooth, which the Sony SRS-XB12 lacks. It links with other speakers (Bose Party mode), which the Sony SRS-XB12 cannot. It has an adjustable EQ, which the Sony SRS-XB12 lacks. The catch: Lack of clarity.
The Sony SRS-XB12 is the longer-running, lighter option. A detachable strap hangs it from a bag or belt. It is rated for 16 hours of battery against 12 for the Bose Soundlink Micro 2. At 0.5 lbs (243 g) it weighs noticeably less than the Bose Soundlink Micro 2 at 0.7 lbs (329 g). The catch: Muddy, with little bass and peaky treble.
Buy the Bose Soundlink Micro 2. It is rated higher for sound quality, and the Sony SRS-XB12 is discontinued, so it is only available used.

Bose Soundlink Micro 2: $129.00 Amazon $129.00 eBay
Older model: the Bose Soundlink Micro (ranked lower, rated 3.5/5). See every Bose SoundLink Flex, Micro, Max and Plus generation.
Same family: the Bose Soundlink Flex 2nd gen (smaller model, rated 3.8/5), the Bose SoundLink Max (smaller model, rated 4.3/5) and the Bose SoundLink Plus (larger model, rated 4.2/5).
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.
