Short answer: the ULT Field 1 for most people, the Ranger if toughness matters most. These rank #56 and #79 out of 142 portable speakers, with the ULT Field 1 at $98 costing noticeably less than the Ranger’s $250.
Battery life is a clear win for the ULT Field 1. Its pros cite a real-world runtime around 28 or more hours with the ULT bass boost mode off, well past the Ranger’s rated 12 plus hours. The ULT Field 1 also survives drops and full submersion to 1 meter and can stereo-pair with a second unit, something the Ranger’s spec sheet doesn’t list.
Sound quality is a mixed bag on both sides. The ULT Field 1’s cons flag an upper midrange peak and rolled off treble, while the Ranger’s cons describe thuddy bass that doesn’t reach as deep as higher ranked speakers. Neither is a standout for tonal accuracy.
Buy the ULT Field 1 for the longer battery life, drop resistance, and lower price.
Buy the Ranger if the magnet mounting and its tougher overall build matter more to you than saving money.

The Two Speakers In Full
Turtlebox Ranger: $250.00 Amazon eBay
Pros: Much better 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
