Customer feedback is positive about sound quality, compact size, battery life, appearance, app features and connections to phones and TVs. That feedback is relevant to a portable speaker with app controls and a claimed 24-hour battery, but it does not establish performance under particular listening conditions. The aggregate ratings are also strongly weighted toward five-star responses, while a smaller share are lower ratings. The supplied feedback does not explain the reasons behind those lower ratings.
