Marshall Emberton II vs Oontz Angle 3 Ultra

Why pick the Marshall Emberton II: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.

The case for the Oontz Angle 3 Ultra: 20+ hour battery life - some reviewers see 22-24 hours at 50% volume. Watch for: Very little bass with horrible upper bass thud at higher levels.

Buy the Marshall Emberton II if sound quality matters more than the price. Buy the Oontz Angle 3 Ultra if the price matters more than sound quality.
