These are a few tech accessories that would make perfect gifts this holiday season. A new phone case is always a good idea and Marc by Marc Jacobs always has so many fun ones. Last year I bought a really cute zebra one for a gift. The power card is useful if you use your phone a lot and it charges any device with a USB port. I keep one in my purse at all times. I would love to receive the headphones this Christmas. They're so sleek!
