Nice cord length. I have not used this bag yet - so this comment only evaluates how the bag attaches to a roof rack. It’s the main reason why I went with this model that allows a wired connection, because I knew Bluetooth in general means a drop in sound quality for any brand of headphones. Still, for what it is, a collection of deep dives into smaller stories that happened on one day in late-1986, it’s a fairly unique, and mostly captivating read. Out of the box, they didnt sound like what I expected. for babies, not 4 year olds! This charging dock has a built in magnetic Apple Watch charges so I didn’t have to worry about putting my Apple Watch charger into the dock (most other charging dock models I looked at required attaching the Watch charger to the dock making for more cords) so this is very convenient. I have foot problems but these shoes help with the pain. Turned on phone Bluetooth, took them out of the box. Respecto a la calidad, me parece muy buena y confortable.
