These headphones have great size. It is nice that they have 40mm drivers in a smaller headphone. They aren't the best for the mountain because they tend to not be as secure, but if you're just cruising sometimes having them around your neck works. For the mountain i would look more towards the Skullcandy icon which stay on great and are a slimmer profile. But for chilling these headphones are sick
I have had this board for a little over a summer now. It has great flex to it and can carve well. It didn't carve as tight as i thought, but that's just cause i had been riding a Sector 9 with gullwing sidewinders. Cruises nice and is super fun.
