Short answer: both are discontinued, so this only matters if you are buying used. Used, the Denon Envaya DSB-250BT is the better pick: it ranks #6 of 172 medium speakers by sound quality (rated 4.4/5), against #10 (rated 4.3/5) for the B&O Beosound A1. If you want one new, the B&O Beosound A1 3rd gen replaces the B&O Beosound A1 and is rated 4.1/5 at $299.99.
Buy the Denon Envaya DSB-250BT only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the B&O Beosound A1 3rd gen, which replaces the B&O Beosound A1.
Battery life favors the B&O Beosound A1: rated for 24 hours against 13 hours for the Denon Envaya DSB-250BT.
