Short answer: the Ultimate Ears Boom 4 for USB-C and a floating IP67 shell, the Klipsch Groove for a balanced stock sound, though neither ranks well in its class. The Groove has pretty balanced sound but is not stereo. The Boom 4 is IP67 rated, floats and charges over USB-C instead of the older Booms’ Micro-USB, though it is not much of an improvement over the old ones. Both are rated below 3.0/5 among the 157 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Buy the Ultimate Ears Boom 4 if sound quality matters more than the price. Buy the Klipsch Groove if the price matters more than sound quality.
If battery life is a priority, the Ultimate Ears Boom 4 is rated for 15 hours versus 8 hours for the Klipsch Groove.
If water resistance matters to you, the Ultimate Ears Boom 4 at IP67 (brief submersion) holds up far better than the Klipsch Groove at IPX4 (splashing).

Klipsch Groove: 9.00 Amazon eBay
Pros: Pretty balanced sound in a compact, splash-resistant form factor. IPX4 water resistance and ~8 hour battery life make it durable for outdoor and poolside use. 3-inch high excursion full-range driver paired with dual side-firing passive radiators.
Cons: Not stereo. Bass doesn’t go as deep as class leaders. Distortion sets in at higher output levels. Older Bluetooth 4.0 architecture without app EQ.
