Design and form factor
Great sound out of a small package. It's very loud and packs a lot of bass, no problem filling a room or using outside on a deck. Easy to pair and use with IOS or Android products. Very heavy, high quality construction. One negative would be that there is so much bass that podcasts aren't as easy to listen to although you can modify this at the source. Also requires a proprietary charger, doesn't use micro USB. Highly recommended, I use it everyday.
