Short answer: the Monster Rockin’ Roller 270, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#104 and #105 of 113 boombox speakers), and the Monster Rockin’ Roller 270 costs $208.99 against $430 for the Turtlebox Gen 3, so with nothing between them on sound quality, price settles it. Both are rated below 3.0/5 among the 113 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $199.99.
The Monster Rockin’ Roller 270 is the deeper-bass, longer-running choice. A wheeled party speaker with an enormous battery, sound spread wide around it and a wireless phone charging pad. Its bass reaches about 53Hz before falling 10dB, against 65Hz for the Turtlebox Gen 3. It is rated for 100 hours of battery against 25 for the Turtlebox Gen 3. It has an adjustable EQ, which the Turtlebox Gen 3 lacks. Watch for: Bass not as deep as competitors, less neutral than ION speakers.
The Turtlebox Gen 3 is the lighter, tougher choice. A loud, waterproof and crushproof outdoor speaker with a big battery, device charging and party mode linking. At 10 lbs (4.54 kg) it weighs much less than the Monster Rockin’ Roller 270 at 28.7 lbs (13 kg). It is rated IP67 against IPX4 for the Monster Rockin’ Roller 270. It links with other speakers (Turtlebox Party Mode), which the Monster Rockin’ Roller 270 cannot. Watch for: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
Buy the Monster Rockin’ Roller 270. Both are rated the same for sound quality, and it costs $221.01 less than the Turtlebox Gen 3.
