Short answer: the JBL Authentics 300 for better sound quality, the W-King D10 for the lower price. The JBL Authentics 300 ranks #44 of 98 boombox speakers, rated 3.5/5, at $499.95. The W-King D10 ranks #76, rated 2.7/5, at $119.98, $379.97 cheaper.
The JBL Authentics 300 is the better-sounding, deeper-bass choice. Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Its bass reaches about 45Hz before falling 10dB, against 60Hz for the W-King D10. It links with other speakers (Wi-Fi Multi-Room), which the W-King D10 cannot. The catch: Narrow sounding, bass not as deep as others.
The W-King D10 is the louder, longer-running pick. 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 100dB for the JBL Authentics 300. It is rated for 42 hours of battery against 8 for the JBL Authentics 300. At 7.9 lbs (3.6 kg) it weighs noticeably less than the JBL Authentics 300 at 10.8 lbs (4.9 kg). Watch for: Upper bass boost, bass not that deep.
Buy the JBL Authentics 300 if sound quality is the priority over the price, or the W-King D10 if the price is the priority over sound quality.
If water resistance matters to you, the W-King D10 at IPX6 (powerful water jets) holds up far better than the JBL Authentics 300 at no water resistance.
