Short answer: the Ultimate Ears Everboom. It ranks #35 of 102 large speakers by sound quality, rated 3.9/5, at $149.99; the Turtlebox Cub ranks #77, rated 3.0/5, and costs $330, so there is not much of a tradeoff to weigh.
The Ultimate Ears Everboom is the better-sounding, longer-running choice. It is rated for 20 hours of battery against 14 for the Turtlebox Cub. At 2.1 lbs (949 g) it weighs much less than the Turtlebox Cub at 5.3 lbs (2.4 kg). Watch for: Careful placement and volume setting remain important for balanced sound.
Why pick the Turtlebox Cub: A compact, cube-shaped Turtlebox at 5.3 lbs (2.4 kg) with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. The catch: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality than the Turtlebox Cub and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Ultimate Ears Everboom: $149.99 Amazon eBay
Pros: Ultimate Ears Everboom uses 2x 56.6mm x 56.2mm fullrange transducers + 2x passive radiators. Its 949 g, claimed 20 hours (Manufacturer specified) battery life, IP67 protection, aux input and mono playback make it a practical option for its intended room or portable use.
Cons: Careful placement and volume setting remain important for balanced sound. Warm tuning with an upper-bass boost and rolled-off treble, and the bass does not go very deep.

Turtlebox Cub: $330.00 Amazon eBay
Pros: A compact, cube-shaped Turtlebox at 2.4 kg with a real two-way layout: a 4.5 inch woofer and a 1.3 inch titanium tweeter. Reviewers found it very loud for its size, with warm, bass-forward tuning and a bit more bass than the Turtlebox Ranger. IP67 waterproof and dustproof, crush and drop resistant, stainless steel tie-downs, a claimed 14+ hours from a 49.95Wh battery, USB-C charging with a power bank output, stereo pairing and Party Mode.
Cons: The evidence so far is listening impressions from two reviews, with no side by side tests against other brands. One reviewer found it loses bass at high volume, and it is not as loud as the full-size Turtlebox. Turtlebox’s claimed 118dB is a figure the brand’s larger speakers have not come close to at a standard one meter distance. It is also mono from one unit, and its recessed USB-C port only fits slim cable plugs.
