POW Audio Taking Orders for Inflatable Speaker Said to Boost Phones' Audio Quality

POW Audio is taking preorders for an expandable Bluetooth speaker designed for smartphones. The $99 speaker can be attached to the back of a phone using a universal mount and then folded down to pocket size when not in use. The company’s WaveBloom technology expands to create a passive radiator, supporting speaker drivers with an air-filled chamber that’s said to provide more bass and volume than what’s possible with a phone’s speaker. The POW speaker can be combined with another to create stereo sound, is water-resistant and is compatible with Bluetooth 4.2 at a range of up to 100 feet, the company said. The speaker charges via USB-C and is said to deliver eight hours of runtime on a charge.
