Even the sound level is better and more. I bought these for a Christmas gift, so with that being said, they have not actually been worn yet. I frequently ride my MTB and theres a lot of jostling and vibration from riding in the woods and this mount holds up well. The installation concept is simple, but nearly impossible to execute properly given the shoddy quality. Still needs help putting it back up, but we are getting there. If those are all from the same manufacturer, they will have the same cross-plate diameter. I lost my Bose QC20 headphones on the plane. I will also be using them to tie bicycles to a car bike carrier rack. It?s almost like you have to put a heavy box on the bottom/shelf to keep it from falling over. I would like to try a size down, since the extra strap material was a bit unwieldy.
