Short answer: the Dali Katch G2, if you are buying new. The Harman Kardon Onyx Studio 4 ranks higher than it (#65 vs #82 of 102 large speakers, 3.3/5 vs 2.8/5) but is discontinued, so only consider it used; the Dali Katch G2 is still sold new at $750.
The Harman Kardon Onyx Studio 4 is the better-sounding choice. Balanced sound quality with deep resonant bass and crisp treble, large dynamic range. It links with other speakers (Connect+ up to 100 speakers), which the Dali Katch G2 cannot. The tradeoff: 8 hour battery at medium volume.
The Dali Katch G2 is the longer-running, lighter choice. Pretty neutral. It is rated for 30 hours of battery against 8 for the Harman Kardon Onyx Studio 4. At 2.4 lbs (1.1 kg) it weighs much less than the Harman Kardon Onyx Studio 4 at 4.5 lbs (2.06 kg). It is rated IPX7, while the Harman Kardon Onyx Studio 4 has no water resistance. Watch for: Loses bass quickly after 40% volume.
Buy the Dali Katch G2 new; the Harman Kardon Onyx Studio 4 is no longer sold new, so it only makes sense as a used find.

Dali Katch G2: $750.00 Amazon eBay
Older model: the Dali Katch G1 (ranked lower, rated 2.8/5).
Pros: Pretty neutral
Cons: Loses bass quickly after 40% volume. A lot of compression artifacts at high volume. External AC power brick for charging. Horribly overpriced. Nearly identical to the Dali Katch G1. Reverb added to the output screws up the imaging. Quite a hollow character to the sound.
