So this is a pretty cool speaker as far as small, portable speakers go. It offers up to 12 hours of play time on a single charge, which is nice when you are planning a day at the beach or park and are going to need music for longer periods of time. It also is pretty small and attractive, so it?s not going to take up space or be an eye sore if you are using it in your home. Plus, it offers quality sound via "Wave Field Synthesis" technology and high fidelity Bluetooth connection. And, of course, it?s great for streaming all your favorite music from Pandora, Spotify and thousands of other streaming applications.
Overall the Core Hi-Fi Wireless Speaker System receives 4.2 out of 5 stars on Amazon, with users claiming it works well as a portable speaker and is satisfying on the whole. However, some users report semi ?shaky? Bluetooth connection and others state it is a bit too expensive when compared to other portable speakers out there.
