Short answer: the Harman Kardon Go + Play 3. It ranks #3 of 98 boombox speakers by sound quality (rated 4.4/5) at $385 and is still sold new; the JBL Boombox ranks #67 (rated 2.9/5) and is discontinued, so it is only an option used. The JBL Boombox’s replacement, the JBL Boombox 4, is rated 4.0/5 at $549.95.
The Harman Kardon Go + Play 3 is the better-sounding pick. Warm sound with boosted bass. It supports AAC Bluetooth, which the JBL Boombox lacks. It has an adjustable EQ, which the JBL Boombox lacks. The catch: Just a little over half as loud as the higher rated boomboxes.
The JBL Boombox is the longer-running, tougher option. Claimed 24 hours (manufacturer specified) battery life, ipx5 protection and stereo playback make its feature set practical for its intended room or portable use. It is rated for 24 hours of battery against 8 for the Harman Kardon Go + Play 3. It is rated IPX5, while the Harman Kardon Go + Play 3 has no water resistance. It links with other speakers (Connect+ up to 100 speakers), which the Harman Kardon Go + Play 3 cannot. The tradeoff: Treble is not very smooth.
Buy the Harman Kardon Go + Play 3. It is rated higher for sound quality, and the JBL Boombox is discontinued, so it is only available used.

Harman Kardon Go + Play 3: $385 Amazon $385 eBay
Older model: the Harman Kardon Go + Play 2 (ranked lower, rated 3.9/5). See every Harman Kardon Go + Play generation.
Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Harman Kardon Go + Play 2. An aux input, a built-in microphone, a power bank function, stereo pairing and hidden button combinations for adjusting bass and treble. Measured bass extension of 35Hz (-10dB).
Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.
Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.
