Short answer: the Ultimate Ears Everboom. It ranks #35 of 105 large speakers by sound quality (rated 3.9/5) at $159.99 and is still sold new; the Ultimate Ears Megablast ranks #87 (rated 2.8/5) and is discontinued, so it is only an option used.
The Ultimate Ears Everboom is the better-sounding choice. It links with other speakers (PartyUp up to 50 speakers), which the Ultimate Ears Megablast cannot. It has an adjustable EQ, which the Ultimate Ears Megablast lacks. The tradeoff: Careful placement and volume setting remain important for balanced sound.
Why pick the Ultimate Ears Megablast: Alexa integration (Wi-Fi + Bluetooth). It plays in stereo from a single unit, unlike the Ultimate Ears Everboom. The tradeoff: Bass is not very deep compared to the competition.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality, and the Ultimate Ears Megablast is discontinued, so it is only available used.

Ultimate Ears Everboom: $159.99 Amazon $159.99 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.
