5mm cable to be able to use without the adapter, but thus far, this adapter has served its purpose quite well with no issues. I also just love the grateful dead, so this is a nice way to pay tribute to their music (even though the chacos arent actually doing that). 0, which I already have a pair but got damaged after almost two years of almost daily use with a bit of neglect. Good for kicking around the house. Además la L y la R se leen bien. To bad otherwise they would be great. Have a slightly woody quality, won?t cause you any pain - so you can turn them up, not fatiguing at all. And I love how they shut off when they click back into its case. Almost worth it. They are very comfortable and walking in them is so easy and much safer than what I was wearing.
