Short answer: the Ultimate Ears Boom 4 for better sound quality, the Wisetiger F10 for the lower price, though neither ranks well in its class. The Ultimate Ears Boom 4 ranks #99 of 150 medium speakers, rated 2.9/5, at $109.99. The Wisetiger F10 ranks #123, rated 2.5/5, at $25.76, $84.23 cheaper. Both are rated below 3.0/5 among the 150 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
What the Ultimate Ears Boom 4 does well: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. The tradeoff: Not much improvement over the old ones.
Why pick the Wisetiger F10: 25W output power, IPX7 waterproof, 24-hour battery life, Bluetooth 5.3 with 30m range, RGB multicolor LED light show, TWS stereo pairing, AUX input, USB-C charging, built-in microphone, lightweight 550g. The tradeoff: Mids and treble on the harsh side, not much bass.
