Short answer: the Earfun Uboom L for better sound quality, the Klipsch Groove for the lower price. The Earfun Uboom L ranks #1 of 157 medium speakers, rated 4.6/5, at $49.79. The Klipsch Groove ranks #105, rated 2.8/5, at $9, $40.79 cheaper.
The Earfun Uboom L is the better-sounding, longer-running option. One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired. It is rated for 16 hours of battery against 8 for the Klipsch Groove. It is rated IP67 against IPX4 for the Klipsch Groove. It has an adjustable EQ, which the Klipsch Groove lacks. The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
What the Klipsch Groove does well: Pretty balanced sound in a compact, splash-resistant form factor. The tradeoff: Not stereo.
Buy the Earfun Uboom L when sound quality outweighs the price for you, and the Klipsch Groove when the price outweighs sound quality instead.

The Two Speakers In Full
Earfun Uboom L: $49.79 after coupon UBOOMLWC Amazon EarFun eBay
Pros: One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired. IP67 protection, indoor/outdoor sound modes and Video Mode make it unusually adaptable; Video Mode substantially improves lip-sync for a single speaker. Measured bass extension of 56Hz (-10dB).
Cons: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail. Low-latency Video Mode disables stereo pairing, so a two-speaker setup is not a good movie system. Firmware and app behavior have also varied over the model’s long life, and the physical controls can be easy to trigger in a bag. Latency is about 400ms by default and 66ms in Video Mode, which you enable by pressing the Bluetooth button twice.
Setup: Try setting up the Earfun App (Android or iOS) to see if that works. If not, you’ll need to flash firmware 1.2.7 to work with the app and set with Oluv’s EQ in the Earfun app which sounds the best. The instructions say that you need a USB3 cable, but most USB2 cables work just fine, try the one included with your phone. Check the current firmware version by turning it on, then pressing the power and Bluetooth buttons at the same time. To flash, turn the speaker off then hold down the Bluetooth button while plugging in the cable. To flash on a mac, see these instructions. In TWS mode, long press the outdoor button for 2 seconds to change TWS to Party mode and back.

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.
