I ordered the blue the first time. Nice dupe for Uggs. ) If worn outside, the soles each have about 30 suction-cup type "mouths" and cuts that seem specifically designed to pick up and hold every pebble that might be in your path - literally filling the bottom of the shoe with stone. The treble is piercing, the bass is lacking and the mids are recessed. Its not really the Grado sound, too much bass for that, but its one of the best true wireless headphones Ive heard. The earbuds are much smaller than I anticipated and fit securely letting me wear them with confidence. The build on these headphones is pretty decent. Just so you know, go down 1 or 1 1/2 sizes. Vielen Dank😊😗! They clearly feel like plastic and are useless.
