Short answer: it depends on whether you want True360 coverage or volume. The B&O Beoplay A2 active spreads B&O’s True360 sound from both sides but is not stereo. The Harman Kardon Go + Play 3 sounds warm with boosted bass, yet is only a little over half as loud as the higher rated boomboxes; at $400 and $385 they sit close on price.
What the B&O Beoplay A2 active gets right: B&O’s True360 sound from both sides. The catch: Not stereo.
On the Harman Kardon Go + Play 3 side: Warm sound with boosted bass. The tradeoff: Just a little over half as loud as the higher rated boomboxes.
One note: the B&O Beoplay A2 active is discontinued, but it still ranks #16 of 78 large speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the B&O Beoplay A2 active at $400 for a large speaker, or the Harman Kardon Go + Play 3 at $385 for a boombox speaker instead.
If battery life is a priority, the B&O Beoplay A2 active is rated for 24 hours versus 8 hours for the Harman Kardon Go + Play 3.

Harman Kardon Go + Play 3: $385 Amazon eBay
Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2. 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.
