Short answer: the Turtlebox Ranger. It ranks #56 of 142 medium portable speakers, while the Ultimate Ears Megaboom 4 sits at #137, near the bottom of the entire class.
The Megaboom 4’s problems go beyond a rough tuning. Reviews describe a lot of distortion at higher volumes, a rolled-off treble, and output that simply isn’t very loud for a speaker this size, a combination summed up as UE having really gotten this one wrong. Its redeeming features are real but don’t compensate: IP67 protection, the ability to float, USB-C charging finally replacing the old micro-USB, a 20-hour battery life, and PartyUp syncing with other UE speakers.
The Ranger’s flaws are more modest by comparison. Its frequency response is called out as much better than other Turtlebox models, though its bass sounds kind of thuddy and doesn’t dig as deep as higher-ranked speakers in its class. It’s also on the heavy side for its size, likely a tradeoff for its rugged build, and reviewers have flagged it as overpriced for what it delivers. None of that puts it in the same territory as the Megaboom 4’s distortion and loudness problems.
If battery life matters more than sound to you, the tradeoff runs the other way: the Megaboom 4 is rated for 20 hours against the Ranger’s 12-plus, and the Ranger’s per-unit price is higher despite it being the better-sounding speaker.
Buy the Turtlebox Ranger if sound quality matters at all. Its bass isn’t class-leading, but it’s a meaningfully more competent speaker than the Megaboom 4.
Buy the Ultimate Ears Megaboom 4 only if battery life, floating in water, or PartyUp syncing with other UE speakers outweighs sound quality for your use case.
If sound quality matters at all to you, skip the Ultimate Ears Megaboom 4. It ranks near the bottom of the 142 medium speakers, so look higher up the list instead.

The Two Speakers In Full
Turtlebox Ranger: $250.00 Amazon eBay
Pros: Smoother frequency response than the other Turtlebox speakers. Has magnets for attaching it to things. Appears to be quite tough
Cons: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers. Overpriced. Heavy for the size, likely due to the toughness
