I wanted decent sound with good balance between lower and upper ranges. Plug and play technology with a dongle that plugs straight into your laptop. The only thing I was not that satisfied about is that the coat rings on the lower and upper piece arent stationary, they are fit on top of other rings slightly loose so they can be spun around. I give these shoes 5 stars out of 5! Bottom Line: These are fantastic ear buds, especially for the price. It also came a bit wrinkly, so itll need steamed. These feel comfortable, and there is definitely more sole/arch support, as well as foot protection from the enclosed toe area. Very smooth to the touch too As good as the original and pop on easily. I LOVE the Sanuk Yoga Sling 2 with the back strap that keeps the shoe on, so I thought Id try this one.
