Short answer: the Ultimate Ears Megaboom 3 if sound quality matters most, the Ultimate Ears Roll 2 if price matters most. The Ultimate Ears Megaboom 3 ranks #83 of 136 medium speakers at $163. The Ultimate Ears Roll 2 ranks #125 at $100, $63 cheaper.
What the Ultimate Ears Megaboom 3 offers: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size. Watch for: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
What the Ultimate Ears Roll 2 offers: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. Built-in bungee cord for hanging from a hook, nail, or door handle. Life-resistant waterproof/dustproof shell. Watch for: Not stereo. Barely any bass, rolled off treble off axis
Buy the Ultimate Ears Megaboom 3 if sound quality is the priority over the price, or the Ultimate Ears Roll 2 if the price is the priority over sound quality.
The Ultimate Ears Roll 2 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
There is a real battery-life gap here: the Ultimate Ears Megaboom 3 is rated for 20 hours, the Ultimate Ears Roll 2 only 9 hours.
