Short answer: the JBL Xtreme for a known quantity, the Everboom for warm tuning. The Everboom has an upper bass boost and is tuned warm with rolled off treble, and our notes say it may move around as better samples arrive. The Xtreme’s 15-hour battery comes with issues with bass distortion at high volumes.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality; the JBL Xtreme is no longer sold new.

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.
