Short answer: the ION Glow Tone. It ranks #68 of 111 boombox speakers by sound quality, rated 3.0/5, at $149; the Turtlebox Gen 3 ranks #103, rated 2.1/5, and costs $430, so there is little reason to consider the other one.
The ION Glow Tone is the better-sounding choice. Jay’s Straight Up Reviews found it reasonably loud with respectable bass and a classy look, and in a head to head it sounded clearer and less muddy than the Zealot ZE21 with wider coverage from its two side firing drivers. It has an adjustable EQ, which the Turtlebox Gen 3 lacks. Watch for: The Zealot ZE21 played about 6 to 7 dB louder in the same comparison, the Glow Tone loses a little bass at maximum volume and showed a slight rattle near 80 percent, and the battery is rated for only about 10 hours.
The Turtlebox Gen 3 is the longer-running, lighter choice. Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. It is rated for 25 hours of battery against 10 for the ION Glow Tone. At 10 lbs (4.54 kg) it weighs much less than the ION Glow Tone at 16.1 lbs (7.3 kg). It is rated IP67 against IPX5 for the ION Glow Tone. Watch for: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
Buy the ION Glow Tone. It is rated higher for sound quality than the Turtlebox Gen 3 and costs less, which makes it the one to get unless you need something the other one does better.
