Background and Identification
Skullcandy is an audio device manufacturer based out of Park City, Utah in the U.S. They produce wired and wireless earbuds, on-ear headsets, and over-ear headphones, mainly marketed toward the extreme outdoor sports demographic. They marketed their headphones by selling them through retailers and outlets geared toward those same demographics.
Skullcandy headphones typically bear their skull logo on all their headsets and bluetooth speakers, so you should be able to find it somewhere on your device.
