Short answer: the Bose Soundlink Revolve+ II for better sound quality, the Ultimate Ears Wonderboom 4 for the lower price. The Bose Soundlink Revolve+ ranks higher than the Ultimate Ears Wonderboom 4 (#53 vs #109 of 175 medium speakers) but is discontinued. Its replacement, the Bose Soundlink Revolve+ II, is rated 3.6/5 at $299; the Ultimate Ears Wonderboom 4 is rated 2.9/5 at $74.50, $224.50 cheaper.
The Bose Soundlink Revolve+ is the better-sounding pick. True 360° sound stays consistent no matter where you stand. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. It links with other speakers (Bose Party mode), which the Ultimate Ears Wonderboom 4 cannot. The tradeoff: Overly boosted bass, warm sounding.
The Ultimate Ears Wonderboom 4 is the lighter, tougher pick. At 0.9 lbs (420 g) it weighs much less than the Bose Soundlink Revolve+ at 2 lbs (910 g). It is rated IP67 against IP55 for the Bose Soundlink Revolve+. It charges over USB-C rather than Micro USB. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Buy the Ultimate Ears Wonderboom 4 if price matters most. For better sound quality, the Bose Soundlink Revolve+ II, the replacement for the discontinued Bose Soundlink Revolve+, is rated higher but costs $299.
