Short answer: the B&O Beosound A1 2nd gen for better sound quality, the Sony ULT Field 3 for the lower price. The B&O Beosound A1 2nd gen ranks #10 of 142 medium speakers at $395. The Sony ULT Field 3 ranks #60 at $138, $257 cheaper.
What the Sony ULT Field 3 offers: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Watch for: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
What the B&O Beosound A1 2nd gen offers: B&O Beosound A1 2nd gen uses 3.5mm aluminium driver + 0.75 inch silk dome tweeter. Its 558 g, claimed 18 hours (Manufacturer specified) battery life, IP67 protection, up to 93dB and mono playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 58Hz specification.
Buy the Sony ULT Field 3 if the price is the priority over sound quality, or the B&O Beosound A1 2nd gen if sound quality is the priority over the price.
