Short answer: the Harman Kardon Go + Play 3. It ranks #3 of 98 boombox speakers by sound quality (rated 4.4/5) at $385 and is still sold new; the W-King H10 ranks #75 (rated 2.7/5) and is discontinued, so it is only an option used.
The Harman Kardon Go + Play 3 is the better-sounding, deeper-bass pick. Warm sound with boosted bass. Its bass reaches about 35Hz before falling 10dB, against 54Hz for the W-King H10. It supports AAC Bluetooth, which the W-King H10 lacks. Watch for: Just a little over half as loud as the higher rated boomboxes.
The W-King H10 is the louder, longer-running option. Comes with wireless microphone. Alan Ross Reviews measured it at 115dB at full volume, against 103dB for the Harman Kardon Go + Play 3. It is rated for 24 hours of battery against 8 for the Harman Kardon Go + Play 3. At 7.1 lbs (3.2 kg) it weighs noticeably less than the Harman Kardon Go + Play 3 at 10.4 lbs (4.7 kg). The tradeoff: Not very deep bass.
Buy the Harman Kardon Go + Play 3. It is rated higher for sound quality and still sold new, while the W-King H10 is discontinued.
If water resistance matters to you, the W-King H10 at IPX6 (powerful water jets) holds up far better than the Harman Kardon Go + Play 3 at no water resistance.

Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Harman Kardon Go + Play 2. An aux input, a built-in microphone, a power bank function, stereo pairing and hidden button combinations for adjusting bass and treble. Measured bass extension of 35Hz (-10dB).
Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.
