The strap slips through a spacer at the top of the bar, but the strap easily pops out of the slot if the strap is not held with tension. Definitely a good purchase if youre looking for wireless earbuds / earphones. My right one doesn?t seem to connect properly and dies quickly. The heavy duty material looks very sturdily and provides against scratches. I did have some trouble getting the case to charge on my wireless mat. There is a plate to keep the rack from rattling, just tighten the u-bolt down as much as you need and the rack is silent. I put these over a toilet in a tiny bathroom to eliminate any items on the limited sink space. Earphone is good. These are super easy to use and Tide always smells the best. They should have kept them how these are and not ruined a fantastic product.
