Short answer: the Marshall Emberton II for battery life, the Yamaha True X Speaker 1A for surround duty, though neither ranks well in its class. The Emberton II runs 30 hours, among the best in its class, and a 20 min quick-charge adds 4 hours, though its sound has a strange echo-like coloration and its bass is not as deep as competitors. The Yamaha peaks in the upper mids, making voices sibilant, and costs $150 against $144.99. Both are rated below 3.0/5 among the 151 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
Buy the Yamaha True X Speaker 1A. It is rated higher for sound quality, and the $5.01 you would save on the Marshall Emberton II does not close the gap.
If battery life is a priority, the Marshall Emberton II is rated for 30 hours versus 12 hours for the Yamaha True X Speaker 1A.
