Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Harman Kardon Go + Play 3 ranks #3 of 91 boombox speakers by sound quality at $385; the Loewe We. Hear Pro ranks #20 of 103 large speakers by sound quality at $275.
What the Harman Kardon Go + Play 3 does well: Warm sound with boosted bass. The tradeoff: Just a little over half as loud as the higher rated boomboxes.
The Loewe We. Hear Pro is the longer-running, lighter pick. It is rated for 24 hours of battery against 8 for the Harman Kardon Go + Play 3. At 4.9 lbs (2.2 kg) it weighs much less than the Harman Kardon Go + Play 3 at 10.4 lbs (4.7 kg). It is rated IPX6, while the Harman Kardon Go + Play 3 has no water resistance. Watch for: It runs out of headroom quickly: above about 70% volume the bass drops away, the treble gets harsher, and near maximum there is heavy compression and clipping, so the JBL Xtreme 4, Harman Kardon Go + Play 3 and Bogasing S8 Pro Max all sound fuller and cleaner when played loud.
Buy the Harman Kardon Go + Play 3 ($385) for a boombox speaker; the Loewe We. Hear Pro ($275) suits a large speaker instead.

The Two Speakers In Full
Harman Kardon Go + Play 3: $385 Amazon 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.

Loewe We. Hear Pro: $275 eBay
Pros: A true stereo speaker with two 70mm woofers, two 25mm tweeters and two passive radiators, and its stereo separation is a standout: in side by side listening it had a wider, more detailed soundstage than the JBL Xtreme 4, with a spacious presentation reminiscent of the old Denon Envaya. At low and moderate volume (up to roughly 60 to 70%) its bass reaches deep enough to shake furniture, and its warm, balanced midrange made it the preferred pick over the Harman Kardon Go + Play 3 and Bogasing S8 Pro Max for background and indoor listening. Bass and treble sliders on the speaker let you tune it without an app. Claimed 24 hours of battery, IPX6 water resistance, USB-C fast charging, a power bank output, an aux input, AAC support and multi-pairing with up to 14 speakers.
Cons: It runs out of headroom quickly: above about 70% volume the bass drops away, the treble gets harsher, and near maximum there is heavy compression and clipping, so the JBL Xtreme 4, Harman Kardon Go + Play 3 and Bogasing S8 Pro Max all sound fuller and cleaner when played loud. At very low volume it benefits from a treble boost. At 2.2kg it is heavy for its size.
