In total, it took me about 15 minutes to get the box unpacked and everything where I wanted it. I haven’t even tried it in the shower. Super easy install. If you have the K701/702 cans powered adequately and the music source you are listening to using AKG K701/K702 cans sounds to you to be strident or muddy, or has a thin bass, or whatever, its the musical source, not AKG K701/K702 headphones; being neutral and flat, they can only reproduce the true content of the source music. They were very thin compared to my other Nike socks I live in South Florida and these are my first wool slippers. Socks resolve this issue, but I bought these for "house slippers" (that I could fetch wood outdoors wearing)* When I take off the shoes, the liners stick to my feet and come out of the shoes, inside-out. It will hopefully serve the intended purpose (I just started using it today). We moved into an apartment with the tiniest kitchen space, and were desperate for more storage space. I am going to try a smaller size and see how that turns out.
