Short answer: the Soundcore Boom 2. It ranks #10 of 120 large speakers by sound quality, rated 4.5/5, at $99.99; the Treblab HD-Max ranks #104, rated 2.4/5, and costs $123.47, so there is not much of a tradeoff to weigh.
The Soundcore Boom 2 is the better-sounding, deeper-bass pick. A light, waterproof large speaker with deep bass for its size, a 24 hour battery and fun lighting. Its bass reaches about 47Hz before falling 10dB, against 60Hz for the Treblab HD-Max. At 3.7 lbs (1.68 kg) it weighs noticeably less than the Treblab HD-Max at 5.1 lbs (2.3 kg). It links with other speakers (PartyCast 2.0 up to 100 speakers), which the Treblab HD-Max cannot. The catch: Only a single midrange driver, so you only get stereo for the tweeters.
The case for the Treblab HD-Max: A very loud, well built boombox with a long tested battery, water resistance, and power bank charging. It keeps a wired aux input, which the Soundcore Boom 2 lacks. Watch for: Boosted upper bass, not much lower bass.
Buy the Soundcore Boom 2. It is rated higher for sound quality than the Treblab HD-Max and costs less, which makes it the one to get unless you need something the other one does better.
