After reading the instructions twice, I commenced the installation process. Very quiet, good sound details. If you can?t get a good fit, you will hear noise in your environment. These are fantastic headphones! I like this shoe rack so much. They broke in 3 days from hitting the corner of a wooden table. Great sandal and the size is perfect. I was originally using Studio3 Beats by Dre (garbage compared to these IMO) they are cool if you dont really care about sound, but I ditched them for these headphones. These are great for joint support when walking- I can pretty much walk 10 miles in these and not feel a thing. The pairing was very quick and easy and they fit very well.
