I tried these on in a local brick n mortar store, but Amazon had them for about 1/2 the price so I thought Id give them a try. I also tested various other tracks that were converted by different methods and they also sounded true to the original. I got this rack to arrange my decoration items and books in my living area. Philips. I havent used them very much over the years but have had the ear cushions split twice, and I think its because theyre squished in the case. Comply foam ear tips. Make sure the bracket bottom edge is flush with the car roof rack rail (say that 3 times fast). Don’t forget you need bolts to connect to the bike itself.
