Short answer: the Earfun Uboom L. It ranks #1 of 144 medium speakers by sound quality, rated 4.6/5, at $49.79; the Klipsch Groove/Heritage Groove ranks #95, rated 2.8/5, and costs $89, so there is little reason to consider the other one.
The case for the Earfun Uboom L: 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. The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
Why pick the Klipsch Groove/Heritage Groove: Pretty balanced sound. The catch: Not stereo.
Buy the Earfun Uboom L. It is rated higher for sound quality than the Klipsch Groove/Heritage Groove and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
There is a real battery-life gap here: the Earfun Uboom L is rated for 16 hours, the Klipsch Groove/Heritage Groove only 8 hours.
If water resistance matters to you, the Earfun Uboom L at IP67 (brief submersion) holds up far better than the Klipsch Groove/Heritage Groove at IPX4 (Groove), none (Heritage Groove) (splashing).

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.

Klipsch Groove/Heritage Groove: $89.00 Amazon eBay
Pros: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life.
Cons: 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.
