Short answer: the Teufel Rockster Air. It ranks #27 of 50 party speakers by sound quality; the Ultimate Ears Hyperboom ranks #31.
On the Teufel Rockster Air side: Exceptional 58-hour battery (31 hours at full volume with ECO mode). User-replaceable battery adds real longevity. 112dB loud like live rock concert. The tradeoff: Peaky midrange, not very natural sounding. Starts to get distorted above half volume.
What the Ultimate Ears Hyperboom offers: Strong audio performance with 2x 4.5” woofers, 2x 1” tweeters, 2x passive radiators. Set against that: Very expensive for what it does, a bit dull and muddy sound. Not as loud as others in the class.
Buy the Teufel Rockster Air if sound quality matters more than the price. Buy the Ultimate Ears Hyperboom if the price matters more than sound quality.
