Short answer: the Ultimate Ears Epicboom, if you are buying new. The Harman Kardon Citation 200 ranks higher than it (#13 vs #83 of 105 large speakers, 4.5/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Epicboom is still sold new at $228.59.
The Harman Kardon Citation 200 is the better-sounding choice. Deeper bass than any Onyx. Watch for: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass, and the Bluetooth and volume up buttons simultaneously to increase it.
The Ultimate Ears Epicboom is the longer-running, lighter option. 17 hour battery with USB-C charging (first UE portable with USB-C). It is rated for 17 hours of battery against 8 for the Harman Kardon Citation 200. At 4.3 lbs (1.97 kg) it weighs noticeably less than the Harman Kardon Citation 200 at 6.3 lbs (2.85 kg). It is rated IPX7 against IPX4 for the Harman Kardon Citation 200. The catch: Not very deep bass for the size.
Buy the Ultimate Ears Epicboom new; the Harman Kardon Citation 200 is no longer sold new, so it only makes sense as a used find.
