Short answer: the Sony ULT Field 1. It ranks #100 of 175 medium speakers by sound quality, rated 3.1/5, at $138; the Marshall Emberton II ranks #127, rated 2.7/5, and costs $144.99, which makes this an easy call rather than a real tradeoff.
The Sony ULT Field 1 is the better-sounding choice. IP67 rated, survives drops and 1m submersion. It supports AAC Bluetooth, which the Marshall Emberton II lacks. Watch for: Upper midrange peak, rolled off treble.
The Marshall Emberton II is the longer-running option. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 30 hours of battery against 12 for the Sony ULT Field 1. It plays in stereo from a single unit, unlike the Sony ULT Field 1. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Sony ULT Field 1. It is rated higher for sound quality than the Marshall Emberton II and costs less, which makes it the one to get unless you need something the other one does better.
