Excerpt: Palm-sized speakers are gaining more and more popularity for their ultra-portable convenience and the affordable price. Everyone wants a little piece of the portable flavored cake, and companies know it. In between the well established players such as the Jambox , comes a mono-speaker so portable you can almost fit it inside your wallet. JBL's On Tour Micro is the kind of portable speaker that takes the word compact and throws it under a roller compactor.
