When you hear the phrase “Bluetooth speaker,” you probably think of a small brick that can fill a room with decent-sounding audio. This is not that kind of speaker.
The Ion Block Rocker though has enough oomph to provide tunes for an entire block party or barbecue, and its 75-hour battery means you don’t even have to worry about plugging it in. As long as you don’t mind buying a refurb, $90 is a fantastic price for a speaker this loud.
