Bose SoundLink Color II vs Ultimate Ears Wonderboom

Last updated: August 20, 2026

Short answer: the Ultimate Ears Wonderboom. It ranks #87 of 136 medium speakers by sound quality at $79; the Bose SoundLink Color II ranks #98 and costs $139, so there is not much of a tradeoff to weigh.

What the Bose SoundLink Color II gets right: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. The tradeoff: Boosted bass on Color II.

What the Ultimate Ears Wonderboom offers: IP67 rated and floats. Set against that: Not stereo, barely any bass, recessed treble.

One note: the Bose SoundLink Color II is discontinued, but it still ranks #98 of 136 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.

Buy the Ultimate Ears Wonderboom. It ranks higher for sound quality than the Bose SoundLink Color II and costs less, so there is no real case for the other one.

If water resistance matters to you, the Ultimate Ears Wonderboom at IPX7 (brief submersion) holds up far better than the Bose SoundLink Color II at IPX4 (splashing).
