Short answer: the Bose Soundlink Micro 2 for better sound quality, the Dayton Audio Boost Mini for the lower price. The Bose Soundlink Micro 2 ranks #18 of 62 small speakers, rated 3.6/5, at $129. The Dayton Audio Boost Mini ranks #38, rated 3.0/5, at $19.98, $109.02 cheaper.
The Bose Soundlink Micro 2 is the better-sounding, longer-running choice. A waterproof mini speaker with a fabric strap for bags and bikes and USB-C charging. It is rated for 12 hours of battery against 6.5 for the Dayton Audio Boost Mini. It supports aptX Bluetooth, which the Dayton Audio Boost Mini lacks. It links with other speakers (Bose Party mode), which the Dayton Audio Boost Mini cannot. The tradeoff: Lack of clarity.
The Dayton Audio Boost Mini is the lighter option. A tiny, very cheap waterproof speaker with an aux input, microSD playback, stereo pairing, and USB-C charging. At 0.4 lbs (185 g) it weighs much less than the Bose Soundlink Micro 2 at 0.7 lbs (329 g). It keeps a wired aux input, which the Bose Soundlink Micro 2 lacks. The catch: Not much bass, mids slightly boosted, highs a little rolled off.
Buy the Bose Soundlink Micro 2 when sound quality outweighs the price for you, and the Dayton Audio Boost Mini when the price outweighs sound quality instead.
