It's been a week since I have, and frankly I'm not disappointed (at the same time ... At 20 ...). The sound is more than adequate if not good quality. The volume is loud enough to make music in a great piece! The design and materials are great.
By cons, the buttons are ... Cheap. This is not a defeat but it's spot. Then, to the distance between the speaker and the phone (Nexus 5 in my case) is about 3-4m max. After that jerk. But it's honorable.
