Paid 15$ to post canada because they don?t give prepaid return box. A gray plastic bag was shoved into my mail slot. Bought these for my mum. What has worn is the footbed. We are happy with these clamps. I recommend this highly if youre going to clip this and let it dangle from bag or belt loop. I suffer from flat feet, and struggle with foot pain even with inserts. Update after 9 months of use:Still very happy and have recommenced these to several friends looking for good over ear ANC headphones at a budget. In SoCal, we live in these most of the year. I lost my last bike computer due to a mounting system just like the Garmins.
