Short answer: the Beats Pill 2024. It ranks #78 of 177 medium speakers by sound quality, rated 3.3/5, at $99.95. The Ultimate Ears Wonderboom 2 ranks #110, rated 2.9/5, at $80, $19.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Beats Pill 2024 is the better-sounding, deeper-bass option. A compact waterproof speaker with long battery life, fast charging, a power bank port and stereo pairing. Its bass reaches about 56Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. It is rated for 24 hours of battery against 12 for the Ultimate Ears Wonderboom 2. It supports AAC Bluetooth, which the Ultimate Ears Wonderboom 2 lacks. The tradeoff: Boosted upper bass, somewhat thuddy.
The Ultimate Ears Wonderboom 2 is the lighter choice. A small waterproof speaker that floats and is light enough to toss in a bag for the pool or beach. At 0.9 lbs (420 g) it weighs much less than the Beats Pill 2024 at 1.5 lbs (680 g). Watch for: Not stereo, barely any bass, recessed treble.
Buy the Beats Pill 2024. It is rated higher for sound quality, and saving $19.95 with the Ultimate Ears Wonderboom 2 does not make up for the sound-quality gap.
