Don’t let the size of the Mighty Sound Speaker fool you; this is one powerful bluetooth speaker. At just 3.5” x 1.8” x 0.7”, the Mighty Sound Speaker can slip right inside your pocket for easy transport. Then, when you want some music and your phone’s built-in speaker just won’t cut it, power it up and prepare to be impressed. Made with aluminum, PU leather, and outfitted with a rechargeable lithium battery, the pint-sized speaker is clean and contemporary. Get a full charge in 2.5 hours and enjoy 8 hours of music. Toss the Mighty Sound in your pocket or bag and stop relying on your phone’s pathetic excuse for a speaker.
