Helmet purchased at the Apple store in New York.
After a year of using ultra careful, the headphone has a bad contact side left ear.
Call customer service Bose France: The 2-year warranty is only valid for France, if the headphone was purchased in the U.S., only one year.
Deal offered: standard replacement headset for 200 €
Bose France did not deign to repair a faulty weld on a headphone at 400 €.
