Short answer: the Flip 5 if you carry it everywhere, the XB33 for a stereo, IP67 package. The JBL is compact and light at 1.1 lbs (499 g) with a carry lanyard, though it is not stereo. The Sony XB33 is IP67 rated and lightweight at 2.4 lbs (1.1 kg), but it is not very loud.
Buy the Sony XB33 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.
