Just peel off the sticker and apply, and the headphones are just as comfortable as they were on day 1. I work in a place where it is allowable to use earphones, but dangerous to block out all the surrounding noises. Great for the skin, but super tricky to get out of the bottle. The sole of these is great -- I can go to the mailroom in them and not feel like I am walking outside in slippers. I definitely recommend it to keep track of your valuables. My hubbys size 14 crocs are on the bottom shelf for reference. But, they remain easy to listen to. No dislikes, bought it for a spare. Cable is very long and charging brick isnt as big as pictures may portray which is good. The first morning I put them on I was surprised how good they felt.
