Sennheiser is offering a trade-in program of sorts for your old headphones. Whether “new, old, broken or used” all you have to do is choose the style of headphones that you want to purchase, fill out their form, gather up your old headphones and mail them in. The trade-in value depends not on the style of headphones that you are sending in, but on the style that you are getting from Sennheiser. The value will range from $5 for Street Earbuds up to $25 for Noise Canceling models. So if you were thinking about replacing those nasty or broken headphones, Sennheiser may be worth checking out. The trade-in offer is valid from April 1 through July 31.
