Apple has extended its annual back to school promotion. It’s now online (http://tinyurl.com/nl9zv29) and available in some European countries, as well as the U.S. and Canada.

Those who buy an iMac, MacBook, MacBook Pro, MacBook Air or Mac Pro get a free pair of Beats Solo2 On-Ear headphones. There’s also an option to upgrade to a pair of Beats Solo2 Wireless Headphones for $100.

The iPhone, iPad and (for some reason) the Mac mini aren’t among the eligible items for purchase with free headphones. The back to school promo runs through Sept. 18 at Apple Stores.
