Short answer: the Sony ULT Field 1 on measured sound quality, the Klipsch Groove on price. The Sony ULT Field 1 ranks #90 of 157 medium speakers, rated 3.1/5, at $138. The Klipsch Groove ranks #105, rated 2.8/5, at $9, $129 cheaper.
The Sony ULT Field 1 is the better-sounding, longer-running choice. IP67 rated, survives drops and 1m submersion. It is rated for 12 hours of battery against 8 for the Klipsch Groove. It is rated IP67 against IPX4 for the Klipsch Groove. It links with other speakers (Party Connect up to 100 speakers), which the Klipsch Groove cannot. The catch: Upper midrange peak, rolled off treble.
Why pick the Klipsch Groove: Pretty balanced sound in a compact, splash-resistant form factor. It keeps a wired aux input, which the Sony ULT Field 1 lacks. The catch: Bass doesn’t go as deep as class leaders.
Buy the Sony ULT Field 1 if sound quality matters more than the price. Buy the Klipsch Groove if the price matters more than sound quality.
