It has been too cold to wear them outside so they have only been worn in the house as slippers. in 2000. Sweet. Would like a refund or replacement. The comfort is ok. and they feel like new. not loudly though. Overall, I am happy with my purchase! Amazing sound with deep bass and clear audio for audiobooks. I have tried to contact the company via Amazon to find out where I can purchase replacement caps and all I got back as a reply email was a picture of the rails I purchased.
