Summary: I have had this product for nearly a year and a half now, and I can say, for the price, it has very very very much-so outlasted my expectations. I hated these little mini speakers before this one, and I now know that some can perform adequately given a certain scenario. My current phone is an HTC One M7 and it isn't able to fill my bathroom with music during showers etc. even though it has dual front-facing speakers in it.
Summary: Although I bought the product directly from the company, I am thoroughly happy with my choice. I initially bought the Matrix Audio QUBE in pink and they had ran out of product. A day or so after my order I got an email saying such, and telling me they had given me a free upgrade to the Matrix Audio ONE. I have yet to use the bluetooth capability on it, and I'm not sure I ever will. But I have to give it to them.
Summary: For it's size, cost and design...I am blown away by the sound quality! This speaker is pretty awesome & convenient. The only flaw I really found was that when the volume is turned up, the bass in some songs causes it vibrate & it'll move around...like off the edge of a table or shelf. Easy remedy I found: place it on a tiny hand towel and problem solved!
Summary: The sound is pretty good. I have issues with the function of the product. The button for the volume does not work at all. I have yet to try and see if it works for receiving a call but since that is using the same button, it is probably doubtful.
Summary: Whoever invented this product put a lot of thought not only into the design but most importantly in the aspect of sound quality reproduction. Is it comparable to the Bose Wave product? Of course not, but for the size and money you'll spend, I highly recommend this mobile music master.
