One complaint I have is they are hard to put on if you have socks on. Im more angry that they DO NOT TELL YOU there is a shelf life. Other than that they were ok but I wasnt able to actually wear them to see how they held up. There were some summers I wore them every single day! I like that they are adjustable and that will come in handy when the weather starts to heat up and my feel swell, or, when I eat too much salt! Purchased rope to tie the duffels down. The hardware, on the other hand, was a little flimsy as the Phillips head snapped off while I was drilling it into a stud. Only negatives are that the instructions are truly terrible. Works great and the sound quality is amazing and the price is not bad Not only am I not convinced that NC ever works except in very narrow circumstances, I am skeptical whether any off-the-rack earphone can work in my ears.
