Red is beautiful, but it's a soft coral, so pretty! I love UA

My old Boom 3 lasted 7 years before it stopped charging. Just got the Boom 4 in this soft coral color and it's gorgeous. Paired instantly, sounds fantastic, and feels just as tough as the 3. I've dropped my previous one countless times, even dropped it in the tub, and it never missed a beat. This color is a beautiful muted coral with a pink trim and pale blue loop — honestly the prettiest speaker I've ever seen. The big raised buttons are a lifesaver for nighttime use; I can adjust everything by feel in the dark. Will update if anything goes wrong, but so far I'm thrilled.
