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.

One note: the B&O Beoplay A2 active is discontinued, but it still ranks #16 of 120 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.
