Bought these 2 years ago to see what all the fuss was about. Purchased from an authorized dealer (Amazon). Used about an hour every day for a year to play music when I was working out. Indoor, non-smoking use. I have the original boxes and will use them when shipping.
GR Research offers an upgrade:
