Short answer: the Sony ULT Field 1 on measured sound quality, the Klipsch Groove/Heritage Groove on price. The Sony ULT Field 1 ranks #76 of 136 medium speakers at $98. The Klipsch Groove/Heritage Groove ranks #90 at $89, $9 cheaper.
What the Sony ULT Field 1 offers: IP67 rated, survives drops and 1m submersion. Real-world battery around 28+ hours with ULT (bass boost) mode off. Stereo-pairs with a second ULT Field 1. Watch for: Upper midrange peak, rolled off treble
What the Klipsch Groove/Heritage Groove offers: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life. Watch for: Not stereo. Bass doesn’t go as deep as others its size. Gets distorted at higher levels. Wouldn’t generally recommend these old speakers as they can’t compete with modern speakers for bass performance and features.
Buy the Sony ULT Field 1 if sound quality is the priority over the price, or the Klipsch Groove/Heritage Groove if the price is the priority over sound quality.
If water resistance matters to you, the Sony ULT Field 1 at IP67 (brief submersion) holds up far better than the Klipsch Groove/Heritage Groove at IPX4 (Groove), none (Heritage Groove) (splashing).
