Sound quality is out of this world! And I read a review that a guy had the same problem as I did with the first one I got that the ear piece was broken like a the one I pictured. :-)I may have purchased a lot of these headphones since 2012, 4 of them I just purchased new this month (Sept 2019). however, the kayak holder clamps to roofrack bars via a relatively thing strip and only two bolts. pressing them into place, as that will probably break these in very short order. It fit all of my most important shoes on it and looks very neat and organized. I?m trying to reduce chemicals in the products I bring into my home. Think of a C clamp on a 2x4. It didnt seem to function as the directions indicated- clockwise, counter-clockwise, locking, etc. Just as described.
