Short answer: the Marshall Middleton if sound quality matters most, the Ultimate Ears Epicboom if price matters most. The Marshall Middleton ranks #31 of 77 large speakers at $224.90. The Ultimate Ears Epicboom ranks #57 at $213.41, $11.49 cheaper.
What the Marshall Middleton offers: Very deep bass for the size/weight. Watch for: 5db dip at 1.7khz and 6.3khz. 9khz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.
What the Ultimate Ears Epicboom offers: 17 hour battery with USB-C charging (first UE portable with USB-C). IP67 rating, floats in water. Made mostly from recycled fabric and plastic. Large best-sounding UE portable that still feels portable. 180ft Bluetooth range. Watch for: Not very deep bass for the size. Gets distorted at around 70-80% with bass thuds.
Buy the Marshall Middleton if sound quality is the priority over the price, or the Ultimate Ears Epicboom if the price is the priority over sound quality.
