Last updated: September 30, 2026

Short answer: the W-King H330. It ranks #31 of 89 boombox speakers by sound quality, rated 3.8/5, at $119.99; the JBL Authentics 300 ranks #40, rated 3.5/5, and costs $299.95, so there is little reason to consider the other one.

W-King H330 vs JBL Authentics 300

What the W-King H330 does well: In Jagist’s side by side tests it was picked over the JBL Xtreme 5, came very close to the Harman Kardon Go + Play 3 with cleaner vocals, and sounded clearer and more balanced than the Tronsmart Fiitune X30. Watch for: It isn’t very loud, and the W-King X20s plays louder with punchier bass.

The case for the JBL Authentics 300: Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Watch for: Narrow sounding, bass not as deep as others.

Buy the W-King H330. It is rated higher for sound quality than the JBL Authentics 300 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

W-King H330 ranking card

Pros: In Jagist’s side by side tests it was picked over the JBL Xtreme 5, came very close to the Harman Kardon Go + Play 3 with cleaner vocals, and sounded clearer and more balanced than the Tronsmart Fiitune X30. A 5.5 inch woofer, two 2.5 inch tweeters and a down firing passive radiator give it deep, full bass for its size. A 50Wh battery with 45W USB-C fast charging (about 1.8 hours), Bluetooth 5.4, stereo pairing, a bass boost button, aux, TF card and USB playback, and ambient lighting.

Cons: It isn’t very loud, and the W-King X20s plays louder with punchier bass. Below about 20% volume its DSP makes the bass cut in and out. The factory tuning is V shaped: Storytripper HD found the vocals thin and dry next to the fuller JBL Authentics 300, and the mids can sound recessed. No handle, no app, no water resistance rating, and W-King rates the battery at about 9 hours at 70% volume.
