I've learned from experience that electronics and cool accessories for your teens electronics fall into the category of a safe bet. Both of my teen sons rank their headphones way up there on their favorite items list and now it's my daughter's turn to crave a cool pair.
Pottery Barn Teen has a selection of headphones with cool designs for both boys and girls (boys not pictured). We were sent the brown & pink pair with the XOXO pattern for our review and they are even cuter in person. Better still, they have a fair amount of adjustability and as a result feel quite comfortable. I'm certain these will be a hot holiday item for PBTeen this year as I was impressed with the sound quality and the overall look of this item.
Extra: There are also some fun patterned phone and tablet cases you should take a peek at before checking out.
