I have nothing really much to say about comfortability because Vankyo just really nailed it with this C750. i wont wear them til winter, but its a great sturdy slipper for me. These are some great sounding earbuds, especially for the price. seemed a little pricey when i first purchased but it never broke and charges at a fair pace. It?s a great investment to my gaming set up ??. They don?t get hung on my towel or clothes! We returned. (finally). Overall sound quality is good considering they really are a fairly priced set of earbuds. Which is odd since sometimes Cobian sandals have the opposite issue.
