I tend to be audiobook listener with the occasional switch to music. Most 3rd party cables for my IOSdevices in the past I have had problems with not being able to sync I will get an error ( not supported ) However with the cables I purchased here on Amazon from BSTOEM I have had nothing but a good experience. You have to fiddle with the ear hook to get it in your ear. As an example, the screws used to hold the tracks in can unscrew themselves due to the friction of the passing track, dropping the nut to the bottom of your cabinet. They are my go to shoe for summer and they go with everything. A total waste of money do not buy. Wish the pre drilled holes where spaced for drilling into wall studs, that’s my only complaint. I’m pretty impressed with it. Considering the fact that it does butt up against the neck of the bike you would think they would have made it open to the side or towards the bottom. The color combo works really well for the look of the boat.
