Short answer: the JBL Pulse 6 if sound quality matters most, the Ultimate Ears Wonderboom 4 if price matters most. The JBL Pulse 6 ranks #49 of 164 medium speakers, rated 3.7/5, at $329.95. The Ultimate Ears Wonderboom 4 ranks #106, rated 2.9/5, at $78.95, $251 cheaper.
The JBL Pulse 6 is the better-sounding option. A 63.8mm woofer on 30W RMS and a 16mm tweeter on 10W RMS, with JBL rating the response down to 42Hz, well below the Pulse 5’s 58Hz. It supports AAC Bluetooth, which the Ultimate Ears Wonderboom 4 lacks. It links with other speakers (Auracast), which the Ultimate Ears Wonderboom 4 cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom 4 lacks. The tradeoff: No independent measurements or tested reviews have been published yet, so its real bass extension, loudness and tonal balance can’t be compared with ranked speakers.
The Ultimate Ears Wonderboom 4 is the lighter pick. At 0.9 lbs (420 g) it weighs much less than the JBL Pulse 6 at 3.3 lbs (1.49 kg). The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Buy the JBL Pulse 6 if sound quality is the priority over the price, or the Ultimate Ears Wonderboom 4 if the price is the priority over sound quality.

The Two Speakers In Full
JBL Pulse 6: $329.95 Estimated Amazon eBay
Older model: the JBL Pulse 5 (ranked higher, rated 3.7/5).
Pros: A 63.8mm woofer on 30W RMS and a 16mm tweeter on 10W RMS, with JBL rating the response down to 42Hz, well below the Pulse 5’s 58Hz. IP68 makes it fully dustproof and submersible, a step up from the Pulse 5’s IP67. The 360° light show now runs over an illuminated carry handle too, with 16 themes, a double-tap bedside lamp and a Sunset Mode sleep timer in the JBL One app. Bluetooth 6.0 with SBC, AAC and LC3, lossless playback over USB-C, and Auracast for stereo pairing or linking PartyBox speakers and PartyLight Sticks.
Cons: No independent measurements or tested reviews have been published yet, so its real bass extension, loudness and tonal balance can’t be compared with ranked speakers. It plays in mono from one woofer and one tweeter, so a single unit gives no stereo separation. Battery life is rated at only 12 hours from its 34Wh pack, charging takes up to 4.5 hours, and the USB-C port can’t charge a phone. There is no strap, only the built-in handle.
