Short answer: the Yamaha True X Speaker 1A for its extra role, the Sony SRS-XB20 on price, though neither ranks well in its class. The Yamaha doubles as a wireless surround speaker for True X soundbars or a standalone speaker via Solo mode, but its bass is not very deep and an upper mids peak makes voices sibilant. The Sony costs $21 less and its IPX5 pill shape slides easily into a bag, though it sounds thin at higher volumes. Both are rated below 3.0/5 among the 151 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Buy the Yamaha True X Speaker 1A if you want one new; the Sony SRS-XB20 is discontinued, so only look for it used.
