Short answer: the JBL Go 4 on measured sound quality, the Dayton Audio Boost Mini on price. The JBL Go 4 ranks #30 of 62 small speakers, rated 3.2/5, at $49.95. The Dayton Audio Boost Mini ranks #38, rated 3.0/5, at $19.98, $29.97 cheaper.
The JBL Go 4 is the deeper-bass choice. A pocket sized waterproof mini speaker with a loop for hanging and app EQ. Its bass reaches about 82Hz before falling 10dB, against 95Hz for the Dayton Audio Boost Mini. It links with other speakers (Auracast), which the Dayton Audio Boost Mini cannot. It has an adjustable EQ, which the Dayton Audio Boost Mini lacks. The tradeoff: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume.
The case for the Dayton Audio Boost Mini: A tiny, very cheap waterproof speaker with an aux input, microSD playback, stereo pairing, and USB-C charging. It keeps a wired aux input, which the JBL Go 4 lacks. Watch for: Not much bass, mids slightly boosted, highs a little rolled off.
Buy the JBL Go 4 if sound quality is the priority over the price, or the Dayton Audio Boost Mini if the price is the priority over sound quality.
