Short answer: the JBL Charge Essential 2. It ranks #39 of 175 medium speakers by sound quality, rated 3.8/5, at $74.91; the Ultimate Ears Boom 4 ranks #113, rated 2.9/5, and costs $129.99, so there is little reason to consider the other one.
The JBL Charge Essential 2 is the better-sounding, longer-running pick. A tough, compact 2.1 lbs (930 g) speaker with IPX7 water resistance, USB-C charging, a USB-A power-bank output and a claimed 20-hour battery life. It is rated for 20 hours of battery against 15 for the Ultimate Ears Boom 4. Watch for: It is a pared-back Charge: no app EQ, no PartyBoost/party mode and no stereo-pair option.
The Ultimate Ears Boom 4 is the lighter choice. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. At 1.4 lbs (620 g) it weighs noticeably less than the JBL Charge Essential 2 at 2.1 lbs (930 g). It has an adjustable EQ, which the JBL Charge Essential 2 lacks. It plays in stereo from a single unit, unlike the JBL Charge Essential 2. The catch: Not much improvement over the old ones.
Buy the JBL Charge Essential 2. It is rated higher for sound quality than the Ultimate Ears Boom 4 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
JBL Charge Essential 2: $74.91 Sam’s Club $74.91 eBay
Newer model: the JBL Charge Essential 3 SE, ranked lower, rated 3.7/5, released Apr 2026. It adds app control, adjustable EQ, stereo pairing and party mode.
Older model: the JBL Charge Essential (ranked lower, rated 3.2/5). See every JBL Charge Essential generation.
Pros: A tough, compact 930g speaker with IPX7 water resistance, USB-C charging, a USB-A power-bank output and a claimed 20-hour battery life. It delivers much of the JBL Charge 5’s familiar punch and volume in a simpler package, with bass that reaches roughly 55Hz for this size. Measured bass extension of ~55Hz (-10dB).
Cons: It is a pared-back Charge: no app EQ, no PartyBoost/party mode and no stereo-pair option. It plays mono, has a little less bass authority than the JBL Charge 5, and its IPX7 rating does not promise dust protection. Choose it for a good sale price, not for extra features.
