These are very light, feather light. The box says "kids headphones for school," but they fit my head and ears just fine. I wore them around inside my house for a bit and realized the footbed wasnt lining up with my foot and it was making my ankle hurt. I think a 5 would be too small. After a month the product no longer functions properly. The only problem Ive had is really my own fault. Less wires and incredible mic compared to my old one. Updated 10/17/15 - Quality is not good. Unfortunately they stopped working suddenly after four months- completely dead and the factory reset advised on Sonys website has no effect. Perfect fit on the body
