You can have them dry cleaned and order new liners. However this is my third other GenY purchase and like the second it is a failure. Very modern and stylish earphones and the cord doesnt seem to tangle easily which is good. What can I say about Tevas Mush and Mush II flops that hasnt already been said? Ive been wearing Tevas exclusively for over 20 years and they have never let me down. The branding isn?t in your face which I like. My feet are also tucked up neatly underneath me so that nothing can reach out from under the couch and grab my ankles. * Again, the Synapse software is so bad that Im vividly reminded of how a printer OEM came out with good printers, but defeated their own hardware products with terrible software and drivers totaling 250-500MB in size. The two straps that criss cross are actually one piece. So disappointed in the quality! If you don?t put small drill pockets where set screws lamd the inserts will fall out no matter how many times you tighten them.
