Customers are saying

Customers are enthusiastic about the Onyx Studio 7's exceptional sound quality, rich bass, and impressive volume. Many appreciate its portability and stylish design, finding it easily transportable and aesthetically pleasing. However, some users note that the battery life could be improved, and a few mention the speaker's weight as a minor drawback. Overall, the positive feedback on sound quality and design outweighs the concerns about battery life and weight.

    We tested the speak and the sound quality was good. It was very modern but just didn’t vibe with it and ended up returning it. It’s a nice speaker but just wasn’t what i was looking for after all.
