It mounts up solid. Retailers seem to be abandoning those of us with E+ widths, making us buy slippers which a so long that the toes become tripping hazards, which is a real issue for us seniors. I think I will be buying a pair for my partner! After using these headphones, here are my thoughts. I own more pairs of headphones that I should admit, from more affordable models to big names like Sennheiser and Bose. So Ive had a pair of these controllers for a few weeks - putting them through the paces. And if you really dont like them the return on them is always easy on Amazon that is how I got hooked. I haven?t loaded them up yet, but I put a cargo basket on and it seemed to be solid. Im not a triathlete, so just needed a good bike stand for general maintenance. You feel a difference when they come off and it last quite a while.
