Short answer: the Harman Kardon Luna, for the better rating and genuine IP67 protection. The Luna pairs a 48mm x 90mm woofer with a 20mm tweeter in a 2.5 lbs (1.13 kg) cabinet, though there is no companion app or EQ to adjust its sound. The SoundLink Mini 2 has the same compact aluminum build as the original, and roughly 10 hours of battery life, but boosts upper bass while rolling off treble, and mainboard failures are a common complaint.

SoundLink Mini 2 has the same compact aluminum build as the original Mini and roughly 10 hours of battery life, but boosts upper bass while rolling off treble, and mainboard failures are a common complaint; it’s since been discontinued.
Buy the Harman Kardon Luna for the better rating and genuine IP67 protection. Buy the SoundLink Mini 2 only if you find one discounted and prefer Bose’s house voicing.
Water resistance is not close: the Harman Kardon Luna is rated at IP67 (brief submersion), well ahead of the Bose Soundlink Mini 2 at no water resistance.

Harman Kardon Luna: $290.99 Amazon $290.99 eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5, released Mar 2026. It adds app control and adjustable EQ. See every Harman Kardon Luna generation.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
