Boom 2
Loud, bassy beast; needs EQ, no aux.

Charge 6 is probably your best bet, much better than the 5. The Boom 2 is a great option too but you may find it too big. The Ult 3 is also a really good option but I prefer the Charge
I have a Boombox 2 at home and a Flip 6 in my office. Both are plugged in 24/7. I take them out with me occasionally. Both are still in great condition. If you buy fake products, then you should worry. If you buy genuine products, you have nothing to worry about.
I have played my boombox 2 at full volume, and it never distorts. Even my cheaper W-King speakers don’t distort at max volume, and they get way louder.
Meh I’ll stick with my boom 2 pro. Better price with a incredible eq
Yeah but a JBL Boombox 3 is almost 15lbs and the Soundlink Max is around 5lbs. The Bose is expensive but a great recommendation for its weight class. If OP really only cares about bass and loudness then the Partybox series makes sense, but the 320 is 36lbs and comparing them makes less and less sense. OP might decide that 5lb is a significant enough of a difference to compromise on their stated priorities. The Boom 2 is mentioned but doesn't get the random disproportionate hate the Bose does for some reason.
I used to think this way until I got a Boom 2. Way better than anything I'd heard from Soundcore before.
