This brought the anc up after they softendI tried several here was my experience: I tried a-b testing with an air filter it produces about 78 db of soundThe test productsBrainwavzTheseoriginalwicked cushionResultsBrainwavzanc really badcomfort goodquality/look goodThesequality ok not horrible. My Trek Bike shop has the same one. So far the hooks have held up nicely. Fit my wide instep perfectly! Unfortunately it seems that I have missed a return window, or perhaps it was not part of the purchase terms. He is uplifting , honest and if you ever attempted a journey across America on a bike and failed as I did you can relate to everything he shares. They do shrink a bit after washing. Looks nice especially once you get all your things on it, great purchase and definitely recommend to anyone looking for a little extra storage space and not a massive piece of clunky furniture. You can get up to 60hours if you have a couple features turned off and dont need the volume very loud. I took a star off of comfort because they do make my ears feel hot after a while like I?m wearing earmuffs, but it?s not too terrible and a small trade for the sound quality.
