Short answer: the Flip 6, and it isn’t close. It ranks #13 of 179 medium speakers at $79.95; the Wonderboom 3 ranks #110 at $79.99, $0.04 less.
Our own cons entry for the Wonderboom 3 is unusually pointed. Not stereo, barely any bass, boosted upper bass around 93Hz that cuts heavily at high volume, and a note that the speaker still uses micro USB, which our notes call inexcusable for a product released in 2022, feeding buyers the same hardware over and over.
The Flip 6 is described as a huge sound quality leap over the Flip 5, very neutral and nearly pocket-sized, with only a slight upper mids emphasis as its real complaint.
Buy the Flip 6. The ranking gap here reflects a real, well-documented difference in what you’re getting.
