I have the cord because i used blue tooth ear buds before and to much interface on the plane

You can just change the batteryit works great for cancelling out constant background noise ac heater airplane flying over television etcfor first time users of active noise cancellation

Dont expect to wear these headphones and think that all noises will be cancelled and you will just be in a silent state lookup noise cancellation in google and youll learn what noises are actually cancelled

Ok no way around this

It came in original packaging and saw absolutely no signs of use

The cord is not integrated into the headset it has a mini plug to go into your phone and a smaller pin to go into the headset

I imagine if the cord were permanently integrated into the headset or if the proprietary pin side of the cord were to somehow lock into position it would be better

That is to be expected i guess but annoying enough that i purchased the bluetooth version 35 and gave these corded ones to my wife
