Short answer: the DALI Katch G2, if you are buying new, though neither ranks well in its class. The Ultimate Ears Megablast measures as well as it (#87 vs #84 of 105 large speakers, 2.8/5 vs 2.8/5) but is discontinued, so only consider it used; the DALI Katch G2 is still sold new at $750. Both are rated below 3.0/5 among the 105 large speakers, so if sound quality matters, consider the JBL Xtreme 5 instead, ranked #2 at $399.95.
The DALI Katch G2 is the longer-running pick. A slim 2.4 lbs (1.1 kg) stereo speaker with IPX7 waterproofing, a 30-hour battery, aptX HD Bluetooth and a USB power bank output. It is rated for 30 hours of battery against 16 for the Ultimate Ears Megablast. It supports aptX HD Bluetooth, which the Ultimate Ears Megablast lacks. The catch: Loses bass quickly after 40% volume.
The case for the Ultimate Ears Megablast: A 2.4 lbs (1.1 kg) IPX7 waterproof, drop-proof speaker with Alexa over Wi-Fi, a 16-hour battery and the loudest output in the UE lineup. The catch: Bass is not very deep compared to the competition.
Buy the DALI Katch G2 if you want one new; the Ultimate Ears Megablast is discontinued, so only look for it used.
