I tend to have good luck with Steve Madden shoes, Ive had several of his brand in the past and they really hold up very well, so they were worth every penny spent. The bigger and slightly heavier one is the Model O. My feet are toasty and comfortable. I’m using that one instead. Now I have to order a second pair after 5 weeks of use. When I paused my player and turned off the noise cancelling I was totally blown away by all of the noise around me. The inner hat is adjustable to keep it on your head - two pullable strings that you tighten and tie. I have had the left earbud cut out for a fraction of a second but that was only once out of probably 9 hours of listening so far. However, I find they run too large, stretch out must too fast, and will wear out quickly. Bought these to replace the "standard" leather earpads which wore out pretty quickly due to paper thin leather.
