Short answer: the Harman Kardon Go + Play 3, if you are buying new. The Harman Kardon Go + Play 2 ranks higher than the W-King D10 (#23 vs #76 of 98 boombox speakers) but is discontinued; its replacement, the Harman Kardon Go + Play 3, is rated 4.4/5 at $385 and is still sold new.
The Harman Kardon Go + Play 2 is the better-sounding, deeper-bass pick. Claimed 8 hours (manufacturer specified) battery life, up to 99db and stereo playback make its feature set practical for its intended room or portable use. Its bass reaches about 40Hz before falling 10dB, against 60Hz for the W-King D10. At 5.3 lbs (2.4 kg) it weighs noticeably less than the W-King D10 at 7.9 lbs (3.6 kg). It links with other speakers (Wireless Dual Sound), which the W-King D10 cannot. Watch for: Not as loud as others.
The W-King D10 is the louder, longer-running option. 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ and bass boost, microphone input for karaoke, MicroSD card support, USB playback, TWS pairing. Alan Ross Reviews measured it at 106dB at full volume, against 99dB for the Harman Kardon Go + Play 2. It is rated for 42 hours of battery against 8 for the Harman Kardon Go + Play 2. It is rated IPX6, while the Harman Kardon Go + Play 2 has no water resistance. The tradeoff: Upper bass boost, bass not that deep.
Buy the Harman Kardon Go + Play 3, the replacement for the discontinued Harman Kardon Go + Play 2; it is rated higher for sound quality than the W-King D10.
