Short answer: the JBL Xtreme 4 if you want a removable battery, the Ultimate Ears Everboom if you want to spend less. The Xtreme 4’s headline feature is its removable battery, but the body calls it high priced at $309.95. The Everboom is $149.99, a much smaller outlay, though its upper bass boost and rolled off treble keep it from being the fidelity pick.
The case for the Ultimate Ears Everboom: This speaker may move around as we get better sound samples. The tradeoff: Has an upper bass boost and is tuned warm with rolled off treble.
Buy the Ultimate Ears Everboom. It is rated higher for sound quality than the JBL Xtreme 4 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.

JBL Xtreme 4: $309.95 Amazon B&H Photo Video eBay
Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.
