Short answer: the Soundcore Boom 3i. It ranks #31 of 175 medium speakers by sound quality (rated 4.0/5) at $118.99 and is still sold new; the Bose SoundLink Color II ranks #125 (rated 2.7/5) and is discontinued, so it is only an option used.
The Soundcore Boom 3i is the better-sounding, longer-running choice. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. It is rated for 16 hours of battery against 8 for the Bose SoundLink Color II. It is rated IP68 against IPX4 for the Bose SoundLink Color II. It has an adjustable EQ, which the Bose SoundLink Color II lacks. Watch for: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The Bose SoundLink Color II is the lighter option. Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. At 1.3 lbs (600 g) it weighs noticeably less than the Soundcore Boom 3i at 1.7 lbs (783 g). It links with other speakers (Bose Party mode), which the Soundcore Boom 3i cannot. It plays in stereo from a single unit, unlike the Soundcore Boom 3i. Watch for: Boosted bass on Color II.
Buy the Soundcore Boom 3i. It is rated higher for sound quality and still sold new, while the Bose SoundLink Color II is discontinued.
