Short answer: the Harman Kardon Go + Play 3. It ranks #3 of 98 boombox speakers by sound quality, rated 4.4/5, at $385. The W-King X10-1 ranks #84, rated 2.4/5, at $139.99, $245.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
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 63Hz for the W-King X10-1. It supports AAC Bluetooth, which the W-King X10-1 lacks. Watch for: Just a little over half as loud as the higher rated boomboxes.
The W-King X10-1 is the louder, longer-running choice. Alan Ross Reviews measured it at 108dB at full volume, against 103dB for the Harman Kardon Go + Play 3. It is rated for 42 hours of battery against 8 for the Harman Kardon Go + Play 3. At 6.5 lbs (2.95 kg) it weighs noticeably less than the Harman Kardon Go + Play 3 at 10.4 lbs (4.7 kg). The catch: Rolled off treble, not much bass.
Buy the Harman Kardon Go + Play 3. It is rated higher for sound quality, and the $245.01 you would save on the W-King X10-1 does not close the gap.
If water resistance matters to you, the W-King X10-1 at IPX6 (powerful water jets) holds up far better than the Harman Kardon Go + Play 3 at no water resistance.

Older model: the Harman Kardon Go + Play 2 (ranked lower, rated 3.9/5). See every Harman Kardon Go + Play generation.
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.
Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.
