Soundnetic SN250M headsets are super affordable, disposable personal educational headsets with foam ear cushions, steel-reinforced gooseneck microphone and TRRS plug.
Designed with maximum functionality and affordability in mind, these headsets are ideal for use with tablets, mobile devices, computers, MP3 players, CD players and much more.
Disposable means they are inexpensive and designed for limited use; yet these budget school headphones with microphone can actually last quite awhile with proper care.
