The Two Speakers In Full
Bose Soundlink Micro 2: $129.00 Amazon eBay
Older model: the Bose Soundlink Micro (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.
