Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 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 Harman Kardon Luna is the better-sounding, longer-running option. The sound is fairly balanced apart from the boosted bass. It is rated for 12 hours of battery against 8 for the Bose SoundLink Color II. It is rated IP67 against IPX4 for the Bose SoundLink Color II. It charges over USB-C rather than Micro USB. Watch for: Boosted bass, and less detailed than higher-ranked speakers.
The Bose SoundLink Color II is the lighter choice. Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. At 1.3 lbs (600 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports AAC Bluetooth, which the Harman Kardon Luna lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna. Watch for: Boosted bass on Color II.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the Bose SoundLink Color II is discontinued.
