Woth every penny. The noise cancellation feature is excellent, much better than I expected from a unit for this price, and much better than a few other similar units I have that are much more expensive. These last 5-6 hours on one charge which is fantastic! Soft and warm and a flexible soft sole. I only plan to use it primarily to clamp the top tube, so very little rotation for my use. From day 1 I was in love. So I bought this one instead and was reassured by other Amazon reviewers that it would work and lo and behold it does. Los botones quedaron pegados muy pronto. Too sweet I had Beats and Bose (QC30) , Marshall and some other earphones before, I had to say this product turn out to be the top 2 in sound quality.
